Relay TRS-12VDC-SB-L15 + BJT C1921 + Arduino
As it is known, the microcontroller for obvious reasons can control the electromagnetic relay only through a special driver and most often this driver is the simplest transistor switch. In this article I will calculate the transistor switch for the relay TRS-12VDC...

Dual Display DC Voltmeter / Ammeter H27VI5
H27VI5 is an all in one solution for monitoring voltage and current. This device has several modifications but I want to consider the option with a measurement limit of 100V/10A which has a built-in shunt. Due to the fact that the colours of the wires...
