Lesson 16: Sequence of Colors in RGB LED With Micropython

This tutorial covers using for loops in MicroPython with the Raspberry Pi Pico W to control an RGB LED:

• Introduction: Overview of using for loops and PWM to control RGB LED brightness and color.

• Circuit Setup: Wiring the RGB LED to GPIO pins 13, 14, and 15, using 330 Ohm resistors.

• PWM Setup: Setting up PWM on each LED channel with a frequency of 1000 Hz for smooth transitions.

• Color Sequence Input: Prompting the user for a color sequence, storing inputs in an array.

• Color Control Logic: Using if statements to assign PWM values for colors like red, green, blue, cyan, magenta, yellow, orange, and off.

• Continuous Loop: Cycling through the color sequence using a while true loop with sleep statements.
