Learning to drive can be scary, especially parking your car. Build a wireless car park g alarm with Arduino for extra help! via instructables
Are you or your wife/kids have just learned driving a car and are afraid of getting an ugly dent on it while parking it? Don’t worry, this project is just for you!! The topic already tells much about the project but still telling, it is a wireless car parking alarm that consists of two arduinos connected wirelessly through rf modulation. The transmitter is present at the back of your car that detects the distance between your car and an obstacle. The distance is transmitted and received by the receiver present inside your car that gives you a beep signal. The rate of beeping determines the distance. Faster beeping means that your car is nearer to an obstacle and it can just bang on it if you don’t stop your car.
As already told, the project consists of arduinos both in the transmitter and receiver linked through RF (radio frequency) transmitter and receiver modules. The distance is calculated using an ultrasonic distance sensor that can sense for upto 500cm. Both of them are powered using a 9v battery which makes them portable however the transmitter can be made smaller, hidden and can be powered using your car’s 12v power supply if you want to make it permanent. The project is not very difficult to make and can be easily completed within 3-4 hours. I didn’t add photos of it mounted on my car as it is not present most of the time.
