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 ...

LoRa-Project-with-ESP8266-Arduino-control-Relay 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 ...

Here, we are using a 4 relay module because we will only control four appliances. If you want to automate a different number of appliances, you can use a different relay module. There are many relay ...

These two practical Arduino projects show you how to control a relay from a smartphone using an Arduino Uno either over Bluetooth or over Wi-Fi via an ESP8266 -based ESP-01 module. Whether you are ...

In this DIY project we make a 3-Channel Arduino Relay Shield Circuit for relay based applications. By using this Arduino Relay Shield, we can operate 3 AC appliances at a time.

SIM900-Arduino-Relay-Control This project uses GSM Module (SIM900) with Arduino to switch Relay state by SMS OR CALL.

It is built around Arduino Uno R3 (Board1), HC-05 Bluetooth module, three relays (RL1 through RL3) and a few other components. This project demonstrates how to turn on/off the appliances connected ...
