This project involves designing and constructing a digital tachometer using an Arduino Nano. The tachometer measures the rotational speed of a motor or any rotating object and displays the RPM ...

A DIY Robot comprised of two microcontrollers, namely the ESP32 and Arduino Nano; integrated with multiple sensors. An IR Sensor Array [TCRT5000] for Line Following, Ultrasonic Sensor for Obstacle ...

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 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 ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Abstract: DC motor could be controlled different ways with different approaches. One of the problems has been identifying internal specifications of DC motor such as Torque constant, back-emf constant ...
