The code for this project is written in the Arduino programming language (based on C/C++). It uses the digitalWrite() function to control the state of the LEDs connected to the Arduino pins. The ...

HY-SRF05 work based on Principle of Ultrasonic Echo-Ranging. This module has 2 sensors, one to trigger an ultrasonic waves, and one to receive ultrasonic waves. Trigger Sensor, send a short pulse to ...

[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors. The ...

Here we are presenting an Arduino based low-cost Proximity Sensor Switch to control electric load wirelessly. But before we start to learn how to make this, let’s understand why we need it? Workers’ ...
