The pulse sensor comes with a flat ribbon cable with three male header connectors. The Pinout of the Pulse sensor is given below: S(Signal) is the Analog output pin of the Sensor Module that will give ...

This project focuses on developing a robust temperature monitoring system using an Arduino Uno R3 and an LM35 temperature sensor. The system is designed to precisely measure and display temperature ...

Proximity sensing is a common application for intruder alarms, light switches, and other home and industrial automation applications. There are multiple methods of proximity detection used in the ...

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 ...

In this project, we will build Gas Leak Detection & Alarm System using MQ2 Gas Sensor and Arduino UNO Board. The MQ2 sensor is a versatile gas sensor capable of detecting a wide range of gases as well ...

Sure, the physical build itself looks great, but it’s what [Michael] did with the firmware that impresses us the most. He’s using an Arduino Mega to drive the 7x7x7 cube and manages to squeeze out ...

Here is a 3D light show that will astound you with its combinations. Inexpensive and easy to make thanks to an Arduino controller, the design enables you to play with the existing effects and, most ...

The goal of the capacitive liquid sensor is to measure the change in capacitance or charge between two metal plates depending on the material between them, making it safe to use with any liquid. The ...
