Build Instructions-

Building this is VERY basic.....

1) Parts Needed

• 1× RP2040 microcontroller board (Raspberry Pi Pico or compatible)

• 2× momentary pushbuttons (Button A, Button B)

• 2× LEDs (LEDA, LEDB)

• 2× resistors for LEDs (220Ω typical)

• Jumper wires / breadboard or protoboard

2) Wiring

Buttons (active-low inputs)

Each button connects its GPIO pin to GND when pressed.

• Button A: GPIO 12 

• Button B: GPIO 19 
  

Both buttons go straight to ground.

LEDs (PWM outputs)

Each LED is driven from a GPIO pin through a series resistor to ground:

• LEDA: GPIO 9 

• LEDB: GPIO 22

Both leds to ground.. (use 220 Ohm resistors if you want)

I use PlatformIO.... This project isn't a lesson in programming microcontrollers, so use whatever you like...
