I’ve added a volume controller and servo to the Raspberry Pi Pico, so I’ll upload it.
Sorry for the rough image. This time, I prioritized speed over quality.
Sites I used as reference:
LCD display
Servo (a device that spins)
Right-Left Switch
LED light
For the LED, I used a 330R resistor for red, a 330R resistor for white, and a 330R+220R=550R resistor for blue.
For the switch, I used a 330R resistor.
Please be sure to check the resistors as they may damage the LEDs, etc.
