Question:

Could I add a 2nd colour changing LED to the board using wires? If so what resisted would I need?

    You can add another LED in parallel without any issues. No additional resistor is needed as the one that is in there anyway is a 0 Ohm link. The colour changing LED can accept 2.4V - 5V, your USB port will be at 5V.

Question:

Hi there Is it possible to add a second LED (5mm standard non-flashing) to the circuit, and would I need to add another resistor or solder a different resistor on to the circuit board. Many thanks

    The USB port, the cable and the switch will be fine with the extra current of one additional LED. If you are using a colour changing LED with a standard LED, I?d connect the standard LED and current limit resistor to the board and then connect the colour changing LED to the board afterwards. Whilst the board has a space for a resistor and the kit is supplied with a zero ohm resistor this is nothing more than a wire link. Having connected the standard LED and resistor to the board the flashing LED can be connected across flat edge of the standard LED and the pad on the resistor nearest the mounting hole.
