# Extra Node Information
### Analysis
**72-wordpos** - Analyses the payload and classifies the part-of-speech of each word. The resulting message has msg.pos added with the results. A word may appear in multiple categories (eg, 'great' is both a noun and an adjective).
**74-swearfilter** - Analyses the payload and tries to filter out any messages containing bad swear words. This only operates on payloads of type string. Everything else is blocked.
### Hardware
**37-rpi-piface** - Adds support for the PiFace interface module for Raspberry Pi.
**78-ledborg** - A simple driver for the LEDborg plug on module for Raspberry Pi.
**60-wemo** - Basic node to drive a WeMo socket and switch. Does not use discovery.
**76-blinkstick** - Provides support for the BlinkStick USB LED device.
**77-blink1** - Provides support for the Blink1 USB LED from ThingM.
**78-digiRGB** - Provides support for the DigiSpark RGB USB LED.
**79-sensorTag** - Reads data from the Ti BLE SensorTag device.
**101-scanBLE** - Scans for a particular Bluetooth Low Energy (BLE) device.
### IO
**26-rawserial** - Only really needed for Windows boxes without serialport npm module installed.
Uses a simple read of the serial port as a file to input data. You **must** set the baud rate etc externally *before* starting Node-RED. This node does not implement pooling of connections so only one instance of each port may be used - so in **or** out but **not** both.
**39-wol** - Sends a Wake-On-LAN magic packet to the mac address specified. You may instead set msg.mac to dynamically set the target device mac to wake up.
**88-ping** - Pings a machine and returns the trip time in mS. Returns false if no response received within 3 seconds, or if the host is unresolveable. Default ping is every 20 seconds but can be configured.
### Social
**69-mpd** - MPD music control nodes. Output node expects payload to be a valid mpc command. Currently only simple commands that expect no reply are supported. Input node creates a payload object with Artist, Album, Title, Genre and Date.
**57-notify** - Uses Growl to provide a desktop popup containing the payload. Only useful on the local machine.
**57-prowl** - Uses Prowl to push the payload to an Apple device that has the Prowl app installed.
**57-pushbullet** - Uses PushBullet to push the payload to an Android device that has the PushBullet app installed.
**92-xmpp** - Connects to an XMPP server to send and receive messages.
### Storage
**67-leveldb** - Uses LevelDB for a simple key value pair database.
**68-mysql** - Allows basic access to a MySQL database. This node uses the **query** operation against the configured database. This does allow both INSERTS and DELETES. By it's very nature it allows SQL injection... *so be careful out there...*
### Time
**79-suncalc** - Uses the suncalc module to generate an output at sunrise and sunset based on a specified location. Several choices of definition of sunrise and sunset are available,
### Misc
**99-sample** - A sample node with more comments than most to try to help you get started without any other docs...
