Obstacle Avoiding Bot

This is a basic example code for an obstacle avoiding bot.

Components Used

• HCSR04 sonar sensor
• SG90 servo motor
• yellow motor x 4
• L298N motor driver
• LM2596 Buck converter (DC to DC)

Framework

Arduino

Header Files

Arduino.h
Servo.h

Limitations

• Slow scan due to only one proximity sensor that rotates and reads.
• All contagious motor pins does not support pwm. That forced us to do unnecessary algorithm to drive motors controlling the speed.
