This project aims to create a car that utilizes an ultrasonic sensor to stop the car when it detects an obstacle in front of it. I used Arduino to code this car and utilized a breadboard to build the circuitry for this car. This car is operated on two sets of batteries and an Arduino processor.
For a working demo of this car, please visit my website
The following image showcases the circuit of the car.
A schematic diagram for the sensor can be viewed here and the component list for the circuit can be viewed here.
