git clone https://github.com/LeoLin6/TurretBot.git
cd TurretBotIf you don't already have the Arduino IDE installed, download and install it from the official website:
🔗 https://www.arduino.cc/en/software
- Open Arduino IDE
- Go to:
File→Open→ Navigate toTurretBot/main/src/experiment_arduino/experiment_arduino.ino - Connect your Arduino via USB to your PC.
- Select the correct board and port:
Tools→Board→ Select the correct Arduino board (e.g., Arduino Uno)Tools→Port→ Select the appropriate COM port (note it down, you'll need it for the next step)
- Click Upload (the right-arrow icon) to flash the firmware to the Arduino.
- Make sure you have Python installed (preferably Python 3.x).
- Navigate to the script directory:
cd main/src- Run the script:
python experiment.py- Follow the terminal prompts for calibration and testing positional movement.
💡 Make sure the COM port in the script matches the one your Arduino is using.
