Simple Automatic Moving Robot Using Arduino & L293d IC

This is a basic Robot operated by an arduino and what it does is that it just roams around and follow a circular path by default code but you can modify the code to change the path easily. It is a simple project which anyone can build. .So If You Ever thought about building a robot but thinking that it`s too difficult and costly , well try this, it`s not.This robot uses very simple code and can accomplish the task with ease.

Step 4: Steps:-

Make the chassis ready and find a good place to fix arduino, bread board & Power Bank on the chassis with the help of Double sided tape . And arrange everything on it. Now Follow these steps:-
✔ L293d IC - Power
1.Connect pin 1,8, 9 and 16 together and connect it to 5v Of Breadboard.(Red wire)
2.Connect pin 4,5 & 12,13 together and connect it to Gnd of breadboard.(black wire)
3.Connect your 1st motor to pin 3 and 64.Connect your 2nd motor to pin 11 and 14.
5.5-6 Volts connected to the Breadboard powering the motors& IC.
✔L293d IC - Arduino
1.Pin 2 from L293D IC Connects to Pin 12 on Arduino.
2.Pin 7 from L293D IC Connects to Pin 13 on Arduino.
3.Pin 10 from L293D IC Connects toPin 9 on Arduino
4.Pin 15 from L293D IC Connects to Pin10on Arduino
*."9 Volts battery to powering the Arduino Board"

Step 5: Arduino Program:-
