A 4-pin relay is a simple electrical component used to control a circuit using a small current to switch a larger one. It is commonly used in automotive wiring, lighting systems, and electronic ...

A myriad of electrical gremlins can come to light with a car’s age—bad terminals, broken wires, blown fuses, and even fried relays. Knowing how to diagnose those problems can be the difference between ...

Switching applications involving controlling devices or appliances using digital-I/O lines through a relay often need to indicate the change of state of the I/O line and, hence, the connected device.

The CPC1390G is a 4-pin, single pole and normally open solid state relay that has input to output isolation of 5000 Vrms. It has a blocking voltage of 400 Vp and does not generate EMI or RFI ...

Arduino program to handle relays and control them using switches with support for double-click and long-press. Integration with home automation systems is possible through MySensors integration over ...
