Arduino Self-driving Car using 3 HC-SR04 Ultrasonic Module

Self driven car using HC-SR04 and Servo motor is easy to make and it stops for sometime to check the best possible way to turn the car but if you want to continuously move and turn the car without stopping, it is little complex. We have completed this project using Arduino and HC-SR04 module which is controlling the car and turn it in the right and left if any obstacle comes in front of it without stopping. We used 3 HC-SR04 ultrasonic module, one is in front and two in the left and right of the car, which constantly check for the best possible direction if any object is in front of it and send command to Arduino to turn the car.

Also, if car does not get any space to turn (there is no any apace in front, left and right side of the car), it automatically comes in the back direction and checks for the space to turn in right or left direction.

To provide the power to self direction car, i used 11.1 v LIPO battery because it light weight. You can use 9 to 12v of any battery to provide power.

To Complete this project, below hardwares are used :
1. HC-SR04 Ultrasonic Module
2. Arduino Nano
3. L298n motor driver
4. Smart robot car chassis with 4 wheels and 4 DC Motors
5. Medium Breadboard and
6. Jumper Wires
