While driving a relay with a transistor is something fundamental, this project isn’t really about that per se. It’s about recognizing something that you do too much, and then designing that ...

Transistors want current control, and your microcontroller GPIOs attempt to put out a given voltage. You need a voltage-to-current transformer, otherwise known as a resistor. (See Ohm’s law.) ...

The first transistor computer was built in 1953 by the University of Manchester using 200 point-contact transistors, much in the style of earlier relay and vacuum-tube computers.

DO NOT connect in any ways the main power supply that drive the LOAD to the arduino and transistor circuitry! Turn OFF the relay with delay You can use this code example to introduce a delay in your ...

Welcome to my quick review of an inexpensive 2-channel 5V relay module controlled via RS485 bus utilizing Modbus RTU protocol. As claimed by some online sellers, this easy-to-get Modbus RTU 2-Channel ...

GeneSiC Semiconductor announces the immediate availability of 20 m -1200 V SiC Junction Transistor-Diodes in an isolated, 4-Leaded mini-module packaging that enables extremely low Turn-On energies ...
