🔧 How It Works

1. Print the Template
   Download and print the A4 chassis template from vehicle_body_tmp.pdf.

2. Cut and Fold
   Use scissors and folds as per the template to form the body of the vehicle.

3. Assemble Electronics
   Attach motors, battery, Arduino, and Bluetooth module following the schematic.

4. Upload Code
   Use the provided Arduino code to control the motors based on Bluetooth inputs.

5. Control via Phone
   Pair the Bluetooth module with your phone and control the car using a Bluetooth controller app.
