I had made a simple RGB color mixer using Raspberry Pi Pico. Let's see how I made it.

Hardware Components

1. Raspberry Pi Pico x 1
2. RGB LED x 1
3. 10K POT x 3
4. Wires

Software Components

1. MicroPython

Setting up Raspberry Pi Pico

• Download the micropython firmware from https://micropython.org/download/rp2-pico/
• On the Raspberry Pi Pico, Press the BOOTSEL button and hold it while you connect the other end of the micro USB cable to your computer. This puts your Raspberry Pi Pico into USB mass storage device mode.
• Drag and drop the downloaded .uf2 firmware

Connections 

Make the connections as shown below.

POT1 ->GPIO26

POT2 ->GPIO27

POT3 ->GPIO28

LED_Pin1 -> GPIO14

LED_Pin2 -> GPIO13

LED_Pin3 -> GPIO12

Code

You can find the code on my GitHub repository.

#RGB - Red(14), Green(13), Blue(12)
from machine import Pin, PWM, ADC

	pwm1 = PWM(Pin(14))
	adc1 = ADC(Pin(26))
	pwm2 = PWM(Pin(13))
	adc2 = ADC(Pin(27))
	pwm3 = PWM(Pin(12))
	adc3 = ADC(Pin(28))
	
	pwm1.freq(1000)
	pwm2.freq(1000)
	pwm3.freq(1000)
	
	while True:
	    duty1 = adc1.read_u16()
	    pwm1.duty_u16(duty1)
	    duty2 = adc2.read_u16()
	    pwm2.duty_u16(duty2)
	    duty3 = adc3.read_u16()
	    pwm3.duty_u16(duty3)

Working

We finally did this project successfully.
