Electromechanical components such as relays and switches often must undergo endurance tests that verify their reliability and safety. Regulatory standards typically have compliance criteria that ...

Many microcontroller designs typically mix multiple interfacing methods. A microcontroller (µC) system can be viewed as a system that reads from inputs, performs processing and writes to outputs.

Members can download this article in PDF format. In this design idea, you will learn how to interface two PIC microcontrollers using a wireless 433-MHz RF transmitter/receiver pair to control up to ...

How many remote controls do you have in your home? Don’t you wish all these things were better integrated somehow, or that you could add remote control functionality to a random device? It’s a common ...

SparkFun’s latest tutorial shows you how to work with relays. A relay is an electrically operated switch. In this case, they’re using it to switch a 120V AC outlet. The article carries the standard ...

If you're curious about the function of a relay in the context of home automation and the Internet of Things, here you go. In this piece, we'll explain the practical applications of many different ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...
