Raspberry Pi Pico W - Button Interrupt LED Toggle (MicroPython)

This project demonstrates using hardware interrupts on the Raspberry Pi Pico W to toggle the on-board LED when a push button is pressed.

🧰 Requirements

• Raspberry Pi Pico / Pico W
• Thonny IDE
• MicroPython Firmware

⚙️ Pin Configuration

Component	Pin	Description
LED	On-board	GPIO 25
Push Button	GP16	Input with Pull-up

🧩 Working Principle

• The button press triggers a falling-edge interrupt.
• The interrupt service routine toggles the LED.
• Debounce delay ensures stable operation.

🧠 Code Highlights

• Uses irq() method for interrupt handling.
• Simple debounce using time.sleep().
• Fully compatible with Pico and Pico W.
