 the Metro RP2040. You can run this in Arduino or in Circuit Python. I'm reading an analog pin to read this potentiometer here. I'm actually using PWM to adjust the brightness of this LED here. This was the Zak Hoken Danger Shield. You can see this is just a sort of smorgasbord shield that has a bunch of different fun input and output to play around with and learn and switch this over to Circuit Python. Plug in my Metro RP2040. And you can see now I've got some faders here. They've got LEDs in the fader stems. Adjusting a little buzzer pitch with these little faders that are on here. It is the Metro RP2040.
