This project is a simple people-counting system that uses ultrasonic sensor, an Arduino board, and an LCD display to count the number of people passing through a specific location. The system is ...

Bidirectional Visitor Counter using Arduino UNO and IR Sensor Introduction The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two ...

This Arduino based visitor counter circuit shows how to count visitor from door using Arduino and Apds9960 Geature sensor.

[Todd Harrison] really has our number. Like him, we don’t want to spend money when we don’t have to, and hacking our own solutions is a lot more fun anyway. This time around he’s … ...

Learn how a flex sensor works with its pinout, and hardware explanation, and also explore how to use it with Arduino. We have given the Arduino flex sensor code, circuit and simulation for easy ...

In this tutorial we discussed the Sound sensor, its pinout, working, and how to interface it with Arduino. This article includes a complete Arduino code and circuit diagram along with a step-by-step ...

This article will introduce the WisBlock RAK12014 ToF laser ranging sensor module, and use the WisBlock development board to demonstrate how the module works. What is a ToF laser ranging sensor module ...

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 ...

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...
