Hi guys! This is an easy and basic tutorial for making a Obstacle Avoiding Robot... Read on ...

Step 1: Materials Required

To build the Obstacle Avoiding Robot you will require-

Arduino Uno R3 (we recommend using Arduino Uno r3 but you can also use other boards such as Mega or Nano...)
Arduino Motor Shield(We can also use a Motor Driver instead of it)
Ultrasonic Sensor
Jumper Wires
9V Battery
Power bank(It is not nessecary that you use a power bank to power the Arduino but we reccommend using it but your robot would run perfectly even if you don't use a power bank)
USB Cable (To connect the Arduino to the power bank if you are using one)

Step 2: Wiring

1. Attach the Trig pin to 8 and the echo to the no.7 (Tip: make sure the wire is naked at the end because it has to be crunched inside the motor shield).The GND pin to the ground supply in the Arduino & VCC to the 5V

2. Then attach the motor shield on the Arduino.

3. Connect the Motors and the 9V power supply to the shield
