Large scale digital logic began not with the vacuum tube but the electromechanical relay. Although vacuum tubes were available at the time – and were used on competing machines – Konrad Zuse chose to ...
An important breakthrough has been reached in the development of energy-efficient electronic circuits using transistors based on germanium. A team of scientists from the Nanoelectronic Materials ...
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 ...
Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...
