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 ...

[Ben Jones] just started a new site called Maker-Guide, where he makes some very informative and well produced DIY videos on anything from homemade photography hacks, to controlling an outlet using a ...

“You could’ve done that with a 555 timer.” But what if all you have on hand is an ESP8266? [TechColab] needed to control a solenoid valve with a short pulse via a solid-state relay (SSR) but found ...

Solid-state relays (SSRs) control load currents through solid-state switches such as triacs, SCRs, or power transistors. These elements are controlled by input signals coupled to the switching devices ...

Solid State Relay (SSR) is a solid-state replacement of electro-mechanical relay, and is commonly used for general purpose switching of signals and low power AC/DC loads. It consists of a ...

Modern relay technology has been around since the 1960s, and its main function is to provide automation with electrical isolation for many applications. All relays have two separate circuitries: input ...
