You’re going to build two simple transistor circuits, each using a single transistor. These circuits will allow you to observe the operation of a transistor as an amplifier, just as Walter ...

A transistor is shown ... then breadboard the resulting circuit, and make a tweak here or there if it isn’t quite right. For example I’d pick a collector resistor using Ohm’s Law to deliver ...

[Fileark] built and ESC using an Arduino and has a couple of posts explaining the concept and demonstrating how it works. His test circuit uses six 2N2222 transistors to protect the Arduino from ...
