Object Avoidence Robot

This is a robot which avoids obstacles

needs tinkercad (website)

First you need to add 2 components 1 is Breadboard and another Arduino Uno R3

Add a H-Bridge Motor Driver

You can Find it as H-Bridge Motor Driver or L293D

Now u need to add 2 wires . 1 from 5v to the upper +(plus) line and another from GND to -(minus) line and use the GND Which I used

Now only upper lines are getting battery so for the bottom lines to also get battery we need to connect a wire from upper +(plus) to lower +(plus) and from upper -(minus) to lower -(minus)

Even change colors like I have did

From H-Bridge Motor Driver take wires

From Power 1 to +(plus) line

From Enable 3 &4 to +(plus) line

From Enable 1 & 2 to +(plus) line

From Power 2 to +(plus) line

From H-Bridge Motor Driver take wires

From H-Bridge Motor Driver all 4 grounds to - (minus) line

Add 2 motors and align them

Upper motor as Right Motor

Lower Motor as Left Motor

You can find motors as Hobby Geramotor

Now connect right Motor's positive wire to output 3 and negative in output 4

Now also connect left Motor's positive wire to output 1 and negative in output 2

Now you need to connect both upper and lower wires . Upper wires in D8 and D9 . Upper wires in D10 and D12.

Now click on code and code blocks like this

Now add Ultrasonic Distance Sensor from other components

Now VCC Wire from Ultrasonic Distance Sensor in +(plus) row

Now GND Wire from Ultrasonic Distance Sensor in -(minus) row

Now Trigger Wire from Ultrasonic Distance Sensor D7

Now Echo Wire from Ultrasonic Distance Sensor D6

Delete All Blocks

The blocks should be like this and when u add the sign it should be < and in number 5 rest blocks u have seen
