Bipolar Opamp IC Design

Do you need GPS time on your desk? This article will show you how to use a GPS module to get time, date and your location displayed on an LCD with an Arduino.

Learn about the important characteristics, benefits, and applications of differential signaling, as well as the proper layout techniques for differential signals.

Maybe it's a wireless peripheral indicating when a packet is ready. Maybe it's an external Flash device signaling when data is ready to be read out.

But, try as you might, it seems the best way to see these sort of events is to just `digitalRead()` that pin over and over in your main `loop()` function until something interesting happens. ...or is it?
