Introduction: Obstacle Avoiding Robot - Motor Shield
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
Step 3: Code
The download link is giving down below download & upload it.....

Step 4: You're Done
Once you done all this make sure you send a image of the robot....

Would you mind explaining what a motor shield is and how this whole thing works? Pretty new to this arduino thing ;)

What is a Motor Shield? In the case if we dont have servos or we dont want to use servo we can use dc or atepper motor .For for using them we need motor driver shield.Motor driver shield the ic L239D which is the most used IC for usingVhe motors .Hope you undesrtand now.

So if I want to use a DC motor, I wont need a motor shield?
