Arduino – Obstacle Avoiding Robot (with L293D)

This Tutorial is for anyone getting started with arduino. We will be building an obstacle avoiding robot that uses an ultrasonic HC SR-04 sensor to detect objects and L293D Motor Driver.

Hardware Required:

– Arduino Uno R3
– L293D Motor Driver
– HC-SR04 Ultrasonic Module Distance Sensor for Arduino
– Bracket / Holder for HC-SR04
– DC Motor and Wheel x2
– Bovine Wheel
– Chassis or Plate
– Jumper or Wire
– Battery Holder
– Battery
– Glue Gun or Cable Ties
– Mini Breadboard
