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.

The Arduino puts 5V on the relay pin. → The relay goes on. (Now you can take away your finger from the button) If the Arduino senses water between the two pins → It puts 0V on the relay pin. → The ...

Relays—the electromechanical kind, not the kind of race that requires a team—have been around a long time: since the early 1800s and possibly before. In the world of technology, that is forever ago.

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 ...

Zero - Arduino Try Out 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.

If you're just starting out with Arduino, you might be wondering what projects you can take on to practice your skills. Don’t worry we got you covered. We have created this massive list of 37 beginner ...

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 ...

I designed this relay circuit to function as a DPDT toggle which is controlled by a momentary switch. I strive to keep my circuits simple with little or no integration (555’s, transistors, etc). The ...
