Breathing LED Using Raspberry Pi Pico

Aim

 The goal of this activity is to demonstrate the use of the PWM signal of a Raspberry pi pico board. This PWM signal allows gradual increase or decrease of power supply to the LED.

Materials Required

  1. Raspberry Pi Pico -1    
  2. Breadboard – 1
  3. LED -1
  4. Several Jumper Wires   
  5. 220Ω Resistors – 1   
  6. Micro USB Cable-1
