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 ...

An Arduino nano and relay module with 4 relays (see picture above) was used to simulate and replace the guitar 3-step switch. The project for Arduino is in PlatformIoClamp15. Node-red was used to ...

2nd relay added for a ON/OFF control at certain times. Checkbox on the browser will also activate the relay. Inside of the arduino folder, create a DATA folder for the two html files. The two htm ...

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 ...

Arduino Uno R3 DFPlayer Mini 3 relays I also connected the Ignition Wire to this system — meaning when I turn the key ON or OFF, the Timer Relay gets a pulse too. So no matter if I lock, unlock, or ...
