🚪 Welcome to the Bidirectional Counter Project Repository! This project demonstrates how to create a simple yet efficient bidirectional counter system using Arduino and IR sensors. The counter ...

What do you need to build an Arduino Speed Sensor. Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, and it is also very ...

An IR sensor module, which is used to detect fan’s blade to calculate the rpm, is connected to interrupt 0 means D2 pin of Arduino. Here we have used a stepper motor driver namely L293N module . IN1, ...

The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two Infrared (IR) sensors connected to an Arduino UNO. This bidirectional counter ...

Arduino Uno is used to compute the logics of the two IR sensors. The circuit is controlled through the software loaded in internal memory of the Arduino. The program (bathroom.ino) is written in ...
