Are you ready to bring your Freenove Three-wheeled Smart Car to life? This kit is a fantastic platform for learning about robotics, electronics, and programming with the Raspberry Pi. This guide will get you started on the exciting journey of programming your smart car and unlocking its potential.
Getting Started: Software and Downloads
The first step is to ensure you have all the necessary software and resources. Freenove provides comprehensive support to get you up and running quickly.
To download the essential files for your Freenove car, you have two convenient options:
Using the Terminal:
For users comfortable with command-line interfaces, the quickest method is using git clone. Open your Raspberry Pi terminal and run the following command:
git clone --depth 1 https://github.com/Freenove/Freenove_Three-wheeled_Smart_Car_Kit_for_Raspberry_Pi.gitThis command downloads the repository containing code examples, libraries, and documentation directly to your Raspberry Pi.
Manual Download via Browser:
Alternatively, you can manually download the files through your web browser. Navigate to the Freenove GitHub repository. Click on the green “Clone or download” button and then select “Download ZIP”. Extract the downloaded ZIP file to a location on your Raspberry Pi.

Basic Programming with Python
The Freenove Three-wheeled Smart Car is typically programmed using Python on the Raspberry Pi. Python is an excellent language for beginners due to its readability and extensive libraries.
Here are the fundamental aspects of programming your car:
- Motor Control: You’ll need to control the car’s motors to move it forward, backward, left, and right. This usually involves using Python libraries to send signals to the motor driver circuit board included in the kit. The Freenove documentation and code examples will guide you on the specific libraries and functions to use.
- Sensor Integration: The smart car kit often includes sensors like ultrasonic sensors for obstacle avoidance or line tracking sensors. Programming these sensors involves reading data from them and using that data to make decisions for the car’s movement. For example, you can program the car to stop when the ultrasonic sensor detects an obstacle.
- Example Code Exploration: The downloaded repository contains example code that is crucial for learning. Start by running these examples to understand basic functionalities like motor control and sensor readings. Modify these examples to experiment and gradually build your own programs.
Expanding Your Project
Once you’re comfortable with basic control, you can explore more advanced projects:
- Obstacle Avoidance: Program your car to navigate autonomously by using the ultrasonic sensor to detect and avoid obstacles.
- Line Following: Utilize line tracking sensors to program the car to follow a black line on a white surface. This is a classic robotics challenge and a great way to learn about sensor feedback and control loops.
- Remote Control: Explore options to control your car remotely using a web interface or a mobile app. This can involve setting up a web server on your Raspberry Pi and writing code to receive and process control commands.
