💡 Raspberry Pi Pico W – LED Blink using MicroPython

A simple MicroPython project that blinks the onboard or external LED on the Raspberry Pi Pico W, created using Thonny IDE.

---

🧰 Requirements

• Raspberry Pi Pico W
• MicroPython firmware flashed
• Thonny IDE (latest version)
• USB cable (Data-enabled)

---

⚙️ Setup Instructions

1. Open Thonny IDE
2. Select interpreter:
   • Run → Select Interpreter → MicroPython (Raspberry Pi Pico)
3. Connect your Pico W via USB
4. Save the script as main.py directly onto the Pico
5. Run it → the onboard LED should blink every 0.1 seconds ✨

🧩 Code Breakdown

• machine.Pin("LED", machine.Pin.OUT) → Initializes the onboard LED pin.
• led.toggle() → Flips the LED state.
• time.sleep(0.1) → Adds a short delay (100 ms).

🔧 Customization

Action	Change
Slow blink	time.sleep(0.5)
Fast blink	time.sleep(0.05)
External LED	Replace "LED" with GPIO number (e.g., 15)

🧱 Project Ideas to Extend

• Breathing LED using PWM brightness control
• Wi-Fi-controlled LED (use network module)
• Blink pattern to indicate Wi-Fi connection status
