An RGB LED module can produce almost any colour using these three primary additive colours: Red, Green and Blue. The simplest version of an RGB LED has a combination of 3 separate light-emitting diodes in one package, housed under a clear protective lens

-connect - to gnd

-connect B to gp 4

-connect G to gp 3

-connect R to gp 2

this code prompts the user for a A hex color code and turns the led that colour

import machine

RED_PIN = 2
GREEN_PIN = 3
BLUE_PIN = 4

red_pwm = machine.PWM(machine.Pin(RED_PIN))
green_pwm = machine.PWM(machine.Pin(GREEN_PIN))
blue_pwm = machine.PWM(machine.Pin(BLUE_PIN))

# Function to set the RGB LED color based on a hex value with brightness
def set_led_color(hex_color, brightness=1.0):
    
    red = ((hex_color >> 16) & 0xFF) * brightness
    green = ((hex_color >> 8) & 0xFF) * brightness
    blue = (hex_color & 0xFF) * brightness
    
    red_pwm.duty_u16(int(red * 255))     # Scale to 16-bit PWM (0-65535)
    green_pwm.duty_u16(int(green * 255))
    blue_pwm.duty_u16(int(blue * 255))


while True:
    try:
        # Input a hex color value with #
        hex_color_input = input("Enter a hex color value : ")
        
       
        if hex_color_input.startswith('#'):
           
            hex_color = int(hex_color_input[1:], 16)
            set_led_color(hex_color)
        else:
            print("Invalid input format. Please use '#' followed by a valid hex color.")
    except ValueError:
        print("Invalid input. Please enter a valid hex color value.")
