[Stephen] wired up an opto-isolator so that when the motor runs, the reed switch is triggered but not fried, and the event gets logged in Google Sheets. Any missed meals are weeded out with a ...

One of the simplest methods of galvanic isolation is the humble optocoupler. [David] didn’t just stop at galvanic isolation. He also added ESD protection, over current protection, and multiple ...

By this method, the two flowing currents are electrically isolated. The image below describes the basic operation of an optocoupler. In the gray image at left, current is not being applied via Pin 1, ...
