Using buttons to control RGB LED colours – Raspberry Pi Pico, MicroPython, PWM
Having got my RGB LED to mix my different traffic light colours, I now want to control them using buttons - aka tactile switches - and here's how I did it. Starting with the Raspberry Pi Pico I set up in my previous video ( • Mixing RGB LED ‘traffic light’ colours wit... , learn along with me as I work through the button wiring, basic coding for changing the colours, finishing up with Pulse Width Modulation (PWM) for a fully functioning red/amber/green status indicator.
