This Arduino-based project simulates a two-floor elevator control system. The elevator uses IR sensors to detect the current floor and a single button to switch between floors. A seven-segment display ...

Stepper Motor with IR Sensor This project involves interfacing a stepper motor with an Arduino and controlling it using an IR sensor. The motor will move based on the detection of objects by the IR ...

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 ...

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 ...

In our daily lives, we use thermometers on various occasions and for various purposes, from medical needs to repair and diagnostic purposes. As you know there are different types of thermometers, and ...

With all of the cool features on the Raspberry Pi, it is somewhat notable that it lacks a power button. In a simple setup, the only way to cut power to the tiny computer is to physically remove the ...
