🔥IR Sensor Robot Without Arduino | Simple DIY Robotics Project

Welcome to another exciting DIY Robotics Project!

In this video, I have built a robot without using any Arduino or microcontroller.

This project uses IR sensors, a relay module, BO motors, and a 3.7V battery to create a simple autonomous robot that moves only when an object (like your hand) comes in front of the sensor.

Components Used:
2x BO Motors
4x Robot Wheels
1x IR Sensor
1x Relay Module
1x 3.7V Lithium Battery

How It Works:
When an object comes in front of the IR sensor, it outputs a signal which activates the relay. This relay acts like a switch that powers the motors. This way, the robot only moves when it detects an obstacle or hand in front of it.

No Arduino or Programming Required
Perfect for Beginners
Fun and Educational DIY Robotics
Project
What You Will Learn:
IR sensor working principle
