Setup

Arduino

1. Open led_control.ino in the Arduino IDE.
2. Connect LED1 to pin 8 and LED2 to pin 9 (with resistors in series).
3. Connect Arduino to your PC via USB.
4. Upload the sketch to the Arduino.

Python

1. Open led_control.py.
2. Make sure the port variable matches your Arduino COM port:

   arduino = serial.Serial(port="COM3", baudrate=9600, timeout=1)

   • On Windows: COM3, COM4, etc.
   • On Linux/macOS: /dev/ttyUSB0 or /dev/ttyACM0.
3. Install pyserial if not already installed:

   pip install pyserial

Usage

1. Run the Python script:

   python led_control.py

2. Enter your choice:
   • 1 → Turn on LED1
   • 2 → Turn on LED2
   • 3 → Turn on LED2, LED1
   • 0 → Turn off both LEDs
   • q → Quit the program
