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 ...

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 ...

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 ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

In the realm of DIY electronics, the Arduino UNO has emerged as a versatile platform for a myriad of projects. One such innovative project is the creation of a low-cost thermal camera, as demonstrated ...

This project aims to create a device which can measure and display the operating RPM and AFR of a small combustion engine. A Hall effect sensor is used to sense the magnet in the engine's flywheel ...

The PIR motion sensor consists of 3 pins-VCC, GND, and the Data Output Pin. VCC is the power pin of the module. Out is the data Output pin of the module.it goes high when motion is detected. GND is ...

Abstract: An infrared sensor based prototype of self-adaptive traffic signal control system has been developed in this paper. An autonomous traffic signal system can be an effective measure to ...
