Basic Obstacle Avoidance Using Ultrasonic sensors

Introduction

A project was proposed to make a Robocar that should detect obstacles and avoid them using arduino uno.

Solution

Make the default motion to forward motion while the desired distance limit has not been reached,
If the immediate obstacle is at the limit distance from the car , it turns left and right and checks which side has a less distance to an obstacle therefore avoiding it, This is recursive and repeats until there is a clear path
