status led main button

What is the pin assigned to the status LED of the main button

Actually it can be any of the following A0-A3. You need a digital I/O to drive an LED, of course since the Ax pins are not PWM pins, you might need a series resistance to limit the current depending on the supply you use for the status/accent LED.

Connected the pin a0 with resistance, works well, to give the commands in the main led led of the sword. So, find a solution for the led of the crystal chamber.
