🔘 Raspberry Pi Pico W – LED Control with Button (MicroPython)

This project turns an LED ON when a button is pressed and OFF when released using MicroPython on the Raspberry Pi Pico W.

🧰 Requirements

  • Raspberry Pi Pico W
  • MicroPython firmware installed
  • Thonny IDE
  • Push button + Jumper wires

⚙️ Pin Configuration

Component Pin Mode
Onboard LED "LED" OUTPUT
Button GPIO16 INPUT (PULL-UP)

🚀 Run the Code

  1. Open Thonny IDE
  2. Choose Interpreter → MicroPython (Raspberry Pi Pico)
  3. Connect Pico W via USB
  4. Copy and save code as main.py
  5. Press the button and watch the LED respond instantly 🔆

🧩 Concept

The button input uses a pull-up resistor, keeping it HIGH until pressed.
When pressed → logic LOW → LED turns ON.
When released → logic HIGH → LED turns OFF.

🔧 Try These Next

  • Add debounce delay: time.sleep(0.05)
  • Toggle LED on press (instead of hold)
  • Use Wi-Fi to control LED via button press status
