We have a collection of almost 500+ Arduino projects with Code, Circuit Diagram, and detailed explanations completely free for everyone to build and learn on their own. The IR sensor has a 3-pin ...

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...

There are two types of tachometer - one is mechanical and the other one is digital. Here we are going to design an Arduino based digital tachometer using IR sensor module to detect object for count ...

This project demonstrates how to use an IR infrared sensor module with an Arduino Uno to detect the presence of objects. The IR sensor emits infrared radiation and detects reflected radiation from ...

# Ultrasonic and Infrared Sensor with Arduino Uno ## Overview This project demonstrates how to use both an ultrasonic sensor and an infrared (IR) sensor with an Arduino Uno. The ultrasonic sensor is ...
