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.

Power on the receiver circuit next and wait for five seconds as defined in receiver code. Press pushbutton (S1 or S2) in transmitter circuit to control the corresponding relay in receiver circuit.

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 ...

From the circuit diagram of the module, it is clear that, apart from the module only a few external components are needed to build a relay-driver circuit. Yes, there is a chance to realize one simple ...

FM and Arduino are 2 interesting aspects of electronics. How about a FM receiver circuit using the Arduino you have lying around?

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 ...

For that reason, [Hulk] designed a simple relay module in order to cut the amount of time he spends implementing this solution in his various other projects.

An impressive persistence of vision laser projector built using an Arduino and a hard drive case has been demonstrated by a DIY enthusiast.

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 ...
