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 ...

Experience — or at least education — often makes a big difference to having a successful project. For example, if you didn’t think about it much, you might think it is simple to control the ...

ESP-01 is a tiny and useful piece of hardware. It has a 32-bit MCU, 2.4GHz 802.11 b/g/n WiFi, 1MB flash memory, and several other useful embedded features. Such ...

[George Dewar] and his wife live in a typical 1940’s house in New Zealand , which in case you didn’t know, have a little insulation in the ceiling… and nowhere else. Like most, they put up with the ...

Over the years, control relays of various types have been used by the hundreds — even thousands — to control nearly every function in commercial and industrial processes. Today, many of those ...

London-based roboticist Evangelos Georgiou wants to offer an open-source platform for helping Arduino hobbyists take their projects mobile, thanks to a remote controlled robot called the RK-1 that ...

When voltage sags occur inside or outside of a facility, properly placed power quality mitigation technology will save sensitive equipment from costly shutdowns. The cost of this mitigation equipment ...
