 It only outputs on a change of value - fine for digital inputs, but you can get a lot of data from analogue pins which you must then handle.

 *Note* - some servos will not travel a full 180 degree range so may only accept 30 - 150 degrees for example.
 Please use the `range` node to scale the input appropriately.
