Whenever we need to connect any AC Appliance in our embedded circuits, we use a Relay. So in this arduino relay control tutorial we will simply learn How to interface a Relay with Arduino. Here we are ...

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 ...

The article is a tutorial on how to control 16 relay through Arduino microcontroller with Ethernet shield W5100. Hello, I'm going to share again with another project that helps many of you to solve ...

Resistance of relay coil is measured using a multimeter which turn out to be = 400 ohms. Vin pin of Arduino gives = 12v. So current need to turn on the relay = 12/400 Amps = 30 mA . If both relays are ...
