Innovative IR and Ultrasonic Sensor System with LM324A and AT89S52 Microcontroller

This project integrates an LM324A operational amplifier to create a robust signal amplifier for IR transmission. It utilizes an AT89S52 microcontroller as the decision-making unit, controlling an ultrasonic transmitter and receiver setup. The system can detect obstacles using ultrasonic waves and IR signals, amplifying the received signals for accuracy. An H-Bridge motor controller (L293B) allows for effective motor control based on sensor inputs, making this configuration ideal for automation and robotics applications.
