This project involves controlling a relay using a Light Dependent Resistor (LDR) and an Arduino. The system detects the ambient light intensity using the LDR sensor. Based on the detected light level, ...

Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi.

Connect the relay module to Arduino: VCC to 5V GND to GND IN1 to Digital Pin 2 IN2 to Digital Pin 3 IN3 to Digital Pin 4 IN4 to Digital Pin 5 IN5 to Digital Pin 6 IN6 to Digital Pin 7 IN7 to Digital ...

This paper aims to design a digital overcurrent relay with a characteristic of a standard inverse that can comply to the IEC standard 60255. The overcurrent relay which is used to protect one phase of ...
