Obstacle Avoiding Circuit

This is simple circuit named Obstacle Avoiding Circuit for Robot . With the help of this circuit the will move left whenever there will be a obstacle in front of Robot. It will turn left whenever the distance from Ultra Sonic Sensor to the object is less than 20cm . If the distance from Ultra Sonic Sensors to the object is more than 20 cm then it will move forward .

So, to make the Circuit we only need 5 things which are :-

1 Breadboard (Quantity 1)

2 Arduino (Quantity 1)

3 L29 3D (Quantity 1)

4 Ultra Sonic Sensor (Quantity 1)

5 Motors (Quantity 2)

Do the connections as same as the picture. You can use TinkerCad software or by using real materials but you have do the same connections in both cases.

Do the coding as same as the picture if you want to the left coding.
