By using an Arduino Uno and a single-channel relay module, you can control high-voltage or high-power devices, such as lights, motors, and appliances, from your computer or mobile device. In this blog ...

The relay module will need 5V from Arduino to power up and will get input from four different digital pins of the Arduino. Now let’s connect the relay module to your home appliance. Take the positive ...

Here we have used 6V Relay module. Here to turn on the Relay with Arduino we just need to make that Arduino Pin High (A0 in our case) where Relay module is connected. Below given is Relay Driver ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

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 ...

Controls power in AC load through a TRIAC, performing AC phase cutting with help of a zero-cross detection circuit in a dimmer module. The module used was a RobotDyn AC Dimmer module paired with an ...

My setup is a relay on the 240V line, a programmed temp swing of 5deg, and cool down period of 5 minutes after ac shutdown before it can turn on again to avoid damaging the compressor.

“Arduino Self-Timer” project presented here is a low-component count 60 seconds countdown timer. It can be powered from a 9V compact battery or suitable Arduino AC mains adaptor. Working of the ...
