⏱ Raspberry Pi Pico W – LED Blink Using Hardware Timer (MicroPython)

Demonstrates periodic LED blinking using hardware timers instead of software delays.
This allows the Pico to multitask while the LED toggles automatically.

🧠 Concept

The machine.Timer module triggers a callback at fixed intervals.
Here, it toggles the LED every 1 second (period=1000 ms).

---

🚀 Run the Code

1. Open Thonny IDE
2. Copy this code to your Pico W as main.py
3. The LED blinks once per second without using sleep()

💡 Try Next

• Change blink rate by adjusting period
• Use two timers to blink two LEDs asynchronously
• Combine with sensors for event-based feedback
