This project is to create a push-button controlled panel of LEDs. I'll be using them to illuminate underneath my kitchen counters. Simulation A wiring diagram and simulation can be found at AutoDesk's 123D Circuits. Parts Each LED panel controller requires: 1x Adafruit Trinket Mini 5v. Adafruit. 1x Adafruit Perma-Proto PCB. Adafruit. 1x Pushbutton with 12v illumination. Amazon. 2x IFR510 n-Channel MOSFET. Amazon. 3x 2-port terminal blocks, 1x 3-port terminal block. Amazon.
