5. Automated Headlights Control
Automating the control of your car’s headlights is a small but impactful upgrade. With a Raspberry Pi, you can set up a system that automatically turns your headlights on or off depending on the surrounding light conditions. This helps improve safety, ensuring that your headlights are always on when needed, without the need to manually adjust them. It’s a simple, effective way to add more automation to your vehicle, and it’s particularly useful for those who often forget to turn on their lights when driving in low-light conditions.
To set up this system, you will need a Raspberry Pi, a light sensor, and a relay module to control the headlights. The light sensor measures the ambient light in the car’s environment, and based on its readings, the Raspberry Pi triggers the relay to turn the headlights on or off. This system ensures that the headlights are on during dusk, in tunnels, or when driving through dark areas, providing greater visibility for the driver and improving overall road safety.
Setting up this system involves connecting the light sensor to the Raspberry Pi and configuring it to monitor the ambient light levels. Once the light levels drop below a certain threshold, the system will automatically activate the headlights. You can fine-tune the threshold to ensure that the lights turn on only when necessary. For example, you may want the system to activate the lights at dusk or when entering a tunnel but not during cloudy days.
The benefits of this system are clear, as it reduces the chances of forgetting to turn on your headlights when it’s needed most. In addition to increasing safety, it also ensures that you’re following traffic laws, as many regions require headlights to be on in low-visibility conditions. For those who often drive in rural or poorly lit areas, having the headlights automatically turn on as the sun sets or when entering tunnels ensures that visibility is never compromised.
Advanced customizations could include integrating other sensors, like motion sensors, to trigger the headlights when the car is in motion, even during daytime. This way, the system would activate headlights when needed in low-light conditions but not during daylight hours. Another idea is to use the Raspberry Pi’s capabilities to control not just the headlights but also other lights on the car, such as fog lights or interior lights, based on sensor data.
For anyone who wants a more efficient and automated driving experience, an automated headlight control system is a great project.

To build the system, you will need a Raspberry Pi, a camera (such as a Pi Camera or a USB webcam), ultrasonic sensors, and software like OpenCV for image processing. The ultrasonic sensors will be used to measure the distance to obstacles, while the camera will provide a visual feed of the parking area. Using this combination, the Raspberry Pi can detect parking spots, measure available space, and offer real-time feedback to the driver. By processing the camera feed and sensor data, the system can also alert you if you’re getting too close to obstacles during parking.
Setting up this system involves installing the necessary software, such as OpenCV, on the Raspberry Pi. OpenCV is an open-source computer vision library that allows the Pi to process the camera feed and recognize objects or parking lines. The ultrasonic sensors should be installed on the front and rear bumpers of the car, providing real-time distance readings. The Raspberry Pi then combines this data to determine the best way to park and gives feedback through a display or through a connected smartphone app.
The core feature of the system is parking spot detection. By analyzing the video feed, the system can identify empty parking spaces and determine whether the spot is large enough to fit the car. Additionally, ultrasonic sensors help the system detect obstacles and alert the driver when approaching them too quickly. If you’re attempting parallel parking, the system can guide you step-by-step, showing whether you need to adjust your position to park correctly.
Advanced customization options include integrating the system with a smartphone app or a larger display inside the car for better visibility. The app could send notifications to alert you when a parking spot is available or guide you with step-by-step instructions if you’re parking in tight spaces. You can also add a feature where the system automatically parks the car if you’re within range, providing a semi-autonomous parking solution.
This smart parking system is perfect for drivers who often park in crowded or tight spaces, offering convenience, safety, and peace of mind.
