Circuit Diagram. Below is the circuit diagram for the Arduino Money Counter: Here, I have made a small structure like a POS currency swiping machine using cardboards. In this structure, a colour ...

For Power supply purposes, I decided to use a 12V DC Power Adaptor to power this whole setup through a barrel jack connector. In the below image, you can find our actual hardware setup of our ...

🚪 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 ...

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 ...

MLX90614 Infrared Thermometer. Before we proceed with the tutorial it is important to know how the MLX90614 sensor works. There are many temperature sensors available in the market and we have been ...
