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 IoT project tutorial, I have shown how to make the LoRa Arduino ESP8266 control relay from the Blynk IoT platform with real-time feedback. In this article, I have covered the following ...

SparkFun Single and Qwiic Quad Relay Arduino Library ... The Single, Dual and Quad relays make it possible to control high powered devices using a low powered device like an Arduino. These relays are ...

Solution 1 Connect the GND of the battery to the GND of arduino – common GND. If you are using a 5V relay instead of 12V relay, you only have to connect the arduino GND. I am using a 12V relay. So the ...

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 ...

Arduino has recently announced two new expansions to their Arduino Pro Opta PLC series – the Arduino Pro Opta Ext D1608E and Arduino Pro Opta Ext D1608S, the main difference between the two is that ...
