@ -4,106 +4,135 @@ A collection of nodes for [Node-RED](http://nodered.org). See below for a list.
## Installation
Eventually, the nodes will be npm-installable, but we're not there yet. Until then:
Most of these nodes are available as npm packages. See the list below for the npm package names, or [search npm](https://www.npmjs.org/search?q=node-red-node).
To install
cd node-red
npm install node-red-node-{*filename*}
This repository acts as an overall store for these nodes - and is no longer intended as a way to install them - unless you really do want some bloat.
To manually install using this repo:
1. cd into the `nodes` directory of Node-RED
2. Either:
- download the zip of the repository and extract it
- run `git clone https://github.com/node-red/node-red-nodes.git`
3. npm install any of the individual node dependencies
This is all too manual, so the sooner we npm-enable this stuff the better
3. npm install in any of the node subfolders to install individual node's dependencies
## Contributing
Please read the Contributing section of the main project [README](https://github.com/node-red/node-red/blob/master/README.md)
Now that we support npm installaton of nodes we recommend people post their own via [npm](https://www.npmjs.org/). Please read the [packaging guide notes](http://nodered.org/docs/creating-nodes/packaging.html).
The key points are:
- try to follow the conventions we use (all undocumented at the moment just to make it interesting)
- focus on the UX of the node - make it simple to do simple things and simple to do advanced things. Don't
force a user wanting to do simple things have to wade through the advanced things.
- avoid duplication

node-red-node-badwords
======================
A <a href="http://nodered.org" target="_new">Node-RED</a> node that attempts to filter out messages containing swearwords.
Install
-------
Run the following command in the root directory of your Node-RED install
npm install node-red-node-badwords
Usage
-----
Uses the badwords npm to attempt to filter out messages containing swearwords.

node-red-node-random
====================
A <a href="http://nodered.org" target="_new">Node-RED</a> node that when triggered generates a random number between two values.
Install
-------
Run the following command in the root directory of your Node-RED install
npm install node-red-node-random
Usage
-----
A simple node to generate a random number when triggered.
If integer mode is selected (default) it will return an integer **between and including** the two values given - so selecting 1 to 6 will return values 1,2,3,4,5 or 6.
If floating point mode is selected then it will return a number **between** the two values given - so selecting 1 to 6 will return values 1 < x < 6 .
**Note:** This generates **numbers**.

node-red-node-smooth
====================
A <a href="http://nodered.org" target="_new">Node-RED</a> node that provides several simple smoothing algorithms for incoming data values.
Install
-------
Run the following command in the root directory of your Node-RED install
npm install node-red-node-smooth
Usage
-----
A simple node to provide various functions across several previous values, including max, min, mean, high and low pass filters.
Max, Min and Mean work over a specified number of previous values.
The High and Low pass filters use a smoothing factor. The higher the number the more the smoothing. E.g. a value of 10 is similar to an &alpha; of 0.1. It is analogous to an RC time constant - but there is no time component to this as the code is based on events arriving.
**Note:** This only operates on **numbers**. Anything else will try to be made into a number and rejected if that fails.

node-red-node-beaglebone
========================
A set of <a href="http://nodered.org" target="_new">Node-RED</a> nodes to interface with the GPIO pins of a <a href="http://http://beagleboard.org/black/" target="_new">Beaglebone Black</a>.
Pre-requisites
--------------
Only of use on a BeagleboneBlack board. Should ideally be running the <a href="http://beagleboard.org/latest-images/" target="_new"> latest Debian</a> image - as that has node.js v0.10.x and the bonescript npm preinstalled.
it does also need <b>bonescript</b> - but this is also pre-installed so no need to mark as a dependency...
Install
-------
Run the following command in the root directory of your Node-RED install
npm install node-red-node-beaglebone
Usage
-----
This package provides 5 nodes for use with the BeagleboneBlack board.
###Analogue Input
Reads an analogue pin when triggered by
a message.
The output message topic is the node topic: the output message value is the
scaled analogue input or NaN if a read error occurs.
Simple linear scaling is defined by setting the output values required for input
values of 0 and 1. You can apply more complicated scaling, e.g. for sensor linearisation,
by defining breakpoints at intermediate input values, with the desired output for
each. Values between breakpoints are linearly interpolated.
To reduce the effect of noise, enable averaging. This will read the input pin
voltage ten times in rapid succession for each input message and output the mean value.
###Digital Input
Sends a message with payload 0 or 1 on the first output when the pin changes state, and logs the total time in the active state.
Sends a message with a payload of the current total active time
(in seconds) on the second output at selectable intervals. An input message with topic 'load'
and a numeric payload will set the total active time to that value: any other input message
will reset it to zero.
The active state may be set to be high or low: this only affects the calculation
of the active time, not the pin state value sent on the first output.
The pin state messages may be generated for both directions of change, or for just 0 to 1
or just 1 to 0 changes. This is useful to generate a single message from a button
press. When using buttons or switches, enable debouncing to improve reliability.
###Pulse Input
Pulse input for the Beaglebone Black. Counts input pulses or pulse edges: outputs
total counts and the rate of counts/sec, with scaling.
Sends the total count message on the first output, and the current count
rate message on the second output, at the chosen interval. An input message with topic 'load'
and a numeric payload will set the total count to that value (no scaling is applied):
any other input message will reset it to zero.
###Digital Output
Sets the output pin high or low depending on the payload of the input message. Numeric
payloads > 0.5 are 'high' (1), payloads <= 0.5 are 'low' (0). Other payloads which
evaluate to true are 'high', if not then 'low'. Selecting the Inverting checkbox will
switch the sense of the pin output.
If the Toggle state checkbox is checked, the message content is ignored: successive
messages cause the pin to toggle between 0 and 1.
The pin will be initially set to the given Startup state until the first message arrives:
the Inverting property is not applied to this value.
###Pulse Output
Pulses the output pin for the set time after receiving an input message, unless the
message has a topic including the text 'time' and a numeric payload. In this case, the
the pulse time will be the value of the payload in seconds. If the time from either
source is < 0.001 seconds, no pulse is generated.
In retriggerable mode, a second message within the pulse period will extend the duration
of the pulse by the time value: in non-retriggerable mode, input messages arriving during
the duration of the pulse are ignored.
The pin state of the pulse may be set to either 0 or 1: the output pin will switch
back to the other state after the pulse time. An output message is generated each time
the pin changes state: its payload is the new state (0 or 1).

node-red-node-hbgpio
====================
A <a href="http://nodered.org" target="_new">Node-RED</a> node to read and write the digital IO of a SolidRun HummingBoard.
Install
-------
**This install is for Debian based OS on Hummingboard.**
Run the following command in the root directory of your Node-RED install:
npm install node-red-node-hpgpio
**Note :** This **should** be run as root in order to move and set SUID permissions on a script to talk to the gpio pins. Alternatively you can run as a normal user and then move the file and change permissions manually.
sudo cp node_modules/node-red-node-hpgpio/gpiohb /usr/local/bin/
sudo chmod 4755 /usr/lcoal/bin/gpiohb
Usage
-----
Hummingboard GPIO input and output nodes.
This requires a small script (gpiohb) to run as root in order to work. It should be placed in /usr/local/bin/ and have SUID permissions 4755.
**Note:** We are using the actual physical pin numbers as they are easier to locate.
###Output node
Expects a <b>msg.payload</b> with either a 0 or 1 (or true or false).
Will set the selected physical pin high or low depending on the value passed in.
The initial value of the pin at deploy time can also be set to 0 or 1.
###Input node
Generates a **msg.payload** with either a 0 or 1 depending on the state of the input pin.
The **msg.topic** is set to **pin/{the pin number}**
**Note:** The input node waits for a change on the level of the pin before reading the value - and then resets to wait for the next interrupt - so it is possible to miss very fast changes as we may still be reading the value when the second edge occurs.

node-red-node-ledborg
=====================
A <a href="http://nodered.org" target="_new">Node-RED</a> node to control a <a href="https://www.piborg.org/ledborg" target="_new">PiBorg LedBorg</a> baord for a Raspberry Pi.
Install
-------
Run the following command in the root directory of your Node-RED install
npm install node-red-node-ledborg
Usage
-----
A PiBorg LedBorg LED output node that expects a <b>msg.payload</b> with a three digit rgb triple, from <b>000</b> to <b>222</b>. I.E. there are only 27 possible colours.
See <i><a href="http://www.piborg.com/ledborg/install" target="_new">the PiBorg site</a></i> for more information.
You can also now use a <b>msg.payload</b> in the standard hex format "#rrggbb". The clip levels are :
><pre>0x00 - 0x57 = off<br/>0x58 - 0xA7 = 50%<br/>0xA8 - 0xFF = fully on</pre>
You can also use the @cheerlight colour names - red, amber, green, blue, cyan, magenta, yellow, orange, pink, purple, white, warmwhite, black

node-red-node-piface
====================
<a href="http://nodered.org" target="_new">Node-RED</a> nodes to control a <a href="http://www.piface.org.uk/products/piface_digital/" target="_new">PiFace Digital</a> add-on board for a Raspberry-Pi.
Install
-------
Run the following command in the root directory of your Node-RED install
npm install node-red-node-piface
Pre-reqs
--------
Requires the WiringPi gpio command to be installed in order to work. See the <a href="http://wiringpi.com" target="new">WiringPi site</a> for details on how to do this.
Usage
-----
A pair of input and output Node-RED nodes for the Raspberry Pi PiFace Digital add-on board.
###Output
The PiFace output node will set the selected relay, LED, or pin on or off depending on the value passed in. Expects a <b>msg.payload</b> with either a 1 or 0 (or true or false).
Requires the WiringPi gpio command in order to work (see pre-reqs).
###Input
The PiFace input node generates a <b>msg.payload</b> with either a 0 or 1 depending on the state of the input pin.
You may also enable the input pullup resistor if required.
The <b>msg.topic</b> is set to <i>piface/{the pin number}</i>
Requires the WiringPi gpio command in order to work (see pre-reqs).
<b>Note:</b> This node currently polls the pin every 250mS. This is not ideal as it loads the cpu.

node-red-node-piliter
=====================
A <a href="http://nodered.org" target="_new">Node-RED</a> node to control a Pimorini Pi-LITEr 8 LED add-on board for a Raspberry-Pi.
Install
-------
Run the following command in the root directory of your Node-RED install
npm install node-red-node-piliter
Pre-reqs
--------
Requires the WiringPi gpio command to be installed in order to work. See the <a href="http://wiringpi.com" target="new">WiringPi site</a> for details on how to do this.
Usage
-----
Raspberry Pi-LITEr output node. The Pi-LITEr must be fitted.
Operates in one of 5 different modes :
- Byte Mode - expects a value between 0 and 255, and each of the LEDs represent 1 bit.
- Meter Mode - expects a value between 0 and 8, the led lit corresponds to the input value - like a meter needle.
- Bar Mode - expects a value between 0 and 8, similar to meter - but all the leds up to the value are turned on - like a mini bar chart.
- All LEDs Mode - expects a 1 or 0 - turns on and off ALL the LEDs
- Object Mode - expects a object specifying the LED and state eg. <code>{led:3,state:0}</code> to set LED3 off.
Requires the WiringPi gpio command in order to work.

node-red-node-pibrella
======================
A <a href="http://nodered.org" target="_new">Node-RED</a> node to control a <a href="http://pibrealla.com/" target="_new">Pibrella</a> add-on board for a Raspberry-Pi.
Install
-------
Run the following command in the root directory of your Node-RED install
npm install node-red-node-pibrella
Pre-reqs
--------
Requires the WiringPi gpio command to be installed in order to work. See the <a href="http://wiringpi.com" target="new">WiringPi site</a> for details on how to do this.
Usage
-----
A pair of input and output Node-RED nodes for the Raspberry Pi Pibrella from Pimoroni.
###Output
The output node will set the selected output high (on) or low (off) depending on the value passed in. Expects a <b>msg.payload</b> with either a 0 or 1 (or true or false).
The Buzzer is a divider so low numbers are high notes. 0 is off, and the sensible lowest note is around 250-300. 2 is the highest note. 1 is just a buzz - so you can use 0/1 type inputs.
**Note:** Using the buzzer is known to "kill" audio output via the 3.5mm socket.
###Input
The input node generates a <b>msg.payload</b> with either a 0 or 1 depending on the state of the input pin.
The <b>msg.topic</b> is set to <i>pibrella/{the pin id}</i> - which will be A, B, C, D or R.
<b>Note:</b> This node currently polls the pin every 250mS. This is not ideal as it loads the cpu.

========================
A <a href="http://nodered.org" target="_new">Node-RED</a> node to control a <a href="http://www.blinkstick.com/" target="_new">BlinkStick</a>.
Install
-------
Run the following command in the root directory of your Node-RED install:
npm install node-red-node-blinkstick
Usage
-----
<i><a href="http://www.blinkstick.com" target="_new">BlinkStick</a></i> output node. Expects a <b>msg.payload</b> with one of:
* A hex string <b>"#rrggbb"</b> triple
* <b>"red,green,blue"</b> three 0-255 values as a string
* <b>"random"</b> will generate a random color
* <i><a href="http://www.w3schools.com/html/html_colornames.asp" target="_new">Standard HTML color</a></i> name
* <b>object</b> can override any of the parameters
An object payload can override any of the settings on the node. Omitted parameters are left intact. For example:
{ 'color': 'blue' }
{ 'task': 'blink', 'color': 'red' }
{ 'task': 'pulse', 'color': 'gree', 'duration': 500 }
{ 'task': 'morph', 'color': 'orange', 'duration': 500, 'steps': 20 }

node-red-node-makeymakey
========================
A <a href="http://nodered.org" target="_new">Node-RED</a> node to read from a MakeyMakey input device.
Install
-------
Run the following command in the root directory of your Node-RED install
npm install node-red-node-makeymakey
Pre-reqs
--------
As this requires an underlying npm this also requires it's pre-reqs, see <a href="https://www.npmjs.org/package/node-hid" target="_new">Node-hid npm</a> for more details.
- libudev-dev (Linux only)
- libusb-1.0-0-dev (Ubuntu versions missing libusb.h only)
As this uses the raw HID strea mit often requires you to run Node-RED as root, unless you have correct priviliges.
Usage
-----
Provides "keyboard" like input from a MakeyMakey device.
This uses the hidstream npm module that by default only supports the basic keyboard keys and **NOT** the mouse inputs, fn keys, keypad keys, cursor keys etc. This means that the extra mouse emulation jumpers won't work.
The MakeyMakey can of course be re-programmed to re-assign the keys - but this node doesn't know about that...
Known Issues
------------
1) Every now and then something causes the MakeyMakey HID to become detached (lose focus) from this app and re-attach to another (the in focus) app... whereupon the emulated keys will end up in the wrong window... - Any ideas on how to stop this would be greatly appreciated - but I suspect it's a fundamental issue with the MakeyMakey pretending to be a HID.
2) Default usage is such that you have to run as root. On Debian based systems you can copy the file <i>42-makey.rules</i> to the <code>/etc/udev/rules.d/</code> folder - this should let anyone then access the MakeyMakey. To restart udev use <pre>sudo udevadm control --reload-rules</pre>

node-red-node-sensortag
=======================
This node adds support to Node-RED to read from the Texas Instruments SensorTag.
The SensorTag is a Bluetooth LE device hosting the following sensors:
* Ambient & ir Temperature
* Barometric Pressure
* Humidity
* 3 axis Accelerometer
* 3 axis Magnetometer
* 3 axis Gyroscope
* 2 push Buttons
The config node allows the user to enable/disable any of the sensors listed above. The readings from
these sensors will be sent as a JSON object payload with the sensor name appended to the topic provided:
* Temperature - { topic: [topic_prefix]/temperature, payload: { ambient: 21.2, object: 33.0 } }
* Barometric Pressure - { topic: [topic_prefix]/pressure, payload: { pres: 1000.1 } }
* Humidity - { topic: [topic_prefix]/humidity , payload: { temp: 21.2, humidity: 88} }
* Accelerometer - { topic: [topic_prefix]/ , payload: { x:0.0, y:9.8, z:0.0 } }
* Magnetometer - { topic: [topic_prefix]/ , payload: { x:0.0, y:0.0, z:0.0 } }
* Gyroscope - { topic: [topic_prefix]/ , payload: { x:0.0, y:0.0, z:0.0 } }
* Buttons - { topic: [topic_prefix]/ , payload: { left: "down", right: "up"} }
**NOTE:** Node-RED needs to be run as root inorder or access the Linux Bluetooth 4.0 system calls
