In this Lora project, I have shown how to make the LoRa Arduino ESP8266 control relay using the RYLR896 LoRa module with real-time feedback. So after turning on and off the appliances the receiver ...

This project uses GSM Module (SIM900) with Arduino to switch Relay state by SMS OR CALL. Step 1 (Connect SIM900 With Arduino) Use picture as a reference for connecting SIM900 to Arduino.

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 ...

The receiver is built around Arduino Nano (Board2), Yoda module (YM2), Yoda adaptor(YA2), 2-channel relay module(RM1), and 5V DC power adaptor. Here, the Yoda module acts as an end-node module. The ...

LilyGo T-Relay-8 is an ESP32 WiFi & BLE board equipped with eight 5V relays supporting up to 250V AC or 28V DC, as well as 16-pin GPIO header for expansion. The board offers a more compact solution ...

In this DIY project we make a 3-Channel Arduino Relay Shield Circuit for relay based applications.We designed an isolated PCB for 3 relays. By using this Arduino Relay Shield, we can operate 3 AC ...
