Controlling an LED with Arduino Using an IR Sensor An Infrared (IR) sensor is a commonly used device for proximity detection and object sensing. When combined with an Arduino and an LED, it can create ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...

Photoelectric sensors detect objects and surface changes using variations in optical properties. Each sensor includes a light emitter and a receiver, with most relying on infrared light. In optical ...

Have you ever noticed how shopping malls, parking lots, or event venues seem to track the number of people or cars present inside? You might think they use an AI camera to count them, but in reality, ...

This project is an Arduino-based obstacle-avoiding robot that uses both ultrasonic and infrared (IR) sensors for navigation. The robot moves forward while continuously scanning for obstacles. If an ...

If you have a few hours spare and fancy creating a new Arduino project in your spare time you might be interested in this fun Arduino infrared touchscreen music controller which has been created by ...
