Motors and transistors are very common electronic components. This article aims to provide some of the basics, along with a working code example, circuits and schematics. When a pushbutton connected ...

This DIY FAB Transistor Tester is a compact device designed to identify and measure various electronic components. It uses an ATmega328P-based Arduino UNO to test and display data such as pin ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...
