This article will explore the workings of a relay module and provide a detailed guide on how to interface a single channel relay module with an Arduino.

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 ...

Relay Driver Circuit Explanation: In this 4-Channel Relay Driver Circuit we have used an optocoupler whic his triggered by active LOW signal, to trigger the NPN transistor which further drives the ...

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 ...

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 ...

In conclusion, the Modbus 2-channel 5V relay module is a very useful device for making something Modbus compatible. I found the module relatively straightforward to use, and it seems to do a good job ...

In the Arduino schematic, for some reason pin 2 on the NINA-W102 is labeled "GPIO34". At first I thought I was mistaken, and that pin 2 on the Arduino schematic really is GPIO34 on the NINA, but that ...

The RGB LED module lets you make all sorts of colors with just four pins from the Arduino. Learn how to do it here!
