The BlueHat Signaling Module can drive WS2812 based signal heads or other LED's on the layout.
The color of each LED can be controlled by block detector input, switch statuses, signal aspects, layout power status, button activities, or analog values from e.g. a potentiometer.
The maximum number of LED's that can be driven by BlueHat is only limited by the memory size of the IoTT Stick. More than 1000 LED's is not a problem.
