    Yes you could use a Bi coloured LED, if it’s a 3 legged device this is very straight forward. If it’s a 2 legged device you would just need to sink the current through an NPN transistor to ground, with its gate connected to the LED output.

    A: The board uses an ULN2803A Darlington transistor array IC (IC2 on the board). This can drive 0.5A per channel, so as long as your solenoid uses no more than 0.5A then you can connect it directly to the board without additional drive circuitry. There are 8 inputs on the PICAXE chip so as long as your key pad is configured in a matrix then then there will be enough to go around. There is info on using a key pad in this video.

    Hi Bradley, The voltage range which the PICAXE IC can handle is 4.5-5V. As such a voltage range between this suitable.
