Use your printer port as a high-current ammeter

Posted on Mar 4, 2013

With a few inexpensive components and INT1Ch, you can turn the printer port of your PC into a high-current ammeter. This design`s goal is to make remote high-current measurements, but you can use this technique to remotely measure any other similar analog electrical quantity, such as voltage and charge, at moderate speeds without going for expensive, PC-based general-purpose or tailor-made data-logging add-on cards.
