Step 1: Connect the Motors to the Motor Controller Board
Start by connecting the positive and negative terminals of each motor to the corresponding terminals on the motor controller board. This will enable control of the motors.
Step 2: Connect the Motor Controller Board to the Raspberry Pi
Next, connect the motor controller board to the Raspberry Pi’s GPIO pins according to the manufacturer’s instructions. This connection will allow the Raspberry Pi to communicate with the motors.
Step 3: Connect the Battery Pack to the Motor Controller Board
Connect the positive wire of the battery pack to the motor controller board’s power input and the negative wire to the ground input. This will provide power to the motors and control board.
Step 4: Mount the Raspberry Pi and Motor Controller Board to the Car Chassis
Securely mount the Raspberry Pi and motor controller board to the car chassis using screws or adhesive. This step ensures the stability and proper functioning of the components.
Step 5: Connect the Remote Control Module to the Raspberry Pi
Connect the remote control module to the Raspberry Pi’s GPIO pins as per the manufacturer’s instructions. This connection will enable remote control functionality.
Step 6: Configure the Raspberry Pi
Install the Raspbian operating system on the Raspberry Pi and configure it to control the motors using the GPIO pins. Follow online tutorials for assistance in this step to ensure proper setup.

Step 7: Sign up for a No-IP Account
Sign up for a free No-IP account and create a custom hostname that points to your home network’s IP address. This will enable remote access to your car. You can follow our instructions on getting started on configuring your router to forward traffic to the Raspberry Pi’s IP address. It’s simple, straightforward, and easy to follow.
Step 8: Access Your Car Remotely
With your router properly configured, use your custom No-IP hostname to access your car remotely. Simply enter the hostname into your web browser, and you’ll be able to control the car from anywhere.
