A single-channel relay is an electronic switch that can be controlled by a low-power electrical signal, such as the output from an Arduino microcontroller.By using an Arduino Uno and a single-channel ...

We have the Arduino UNO board which acts as the main brain of this project. The RC522 RFID reader module is used to read the RFID cards and the 16x2 LCD is used to display the status information. The ...

This repository contains the Arduino code for a smart irrigation system using Arduino, moisture sensors, water level, a SIM800L module for SMS notifications, and relay modules for controlling valves ...

This project demonstrates how to create an anti-sleep alarm system for drivers using an Arduino Nano and a Relay Module. The system detects signs of drowsiness or fatigue in the driver and triggers an ...

Circuit with relay driver ULN2003 and relay In this proposed project, we have interfaced Arduino Uno with MQ2/MQ6 sensors, SIM900A GSM module, servo motor, buzzer, and LED. The interfacing is done in ...
