A teacher I know is stuck, with only npn transistors in the supply cupboard and the need to create a reversible motor drive for an Arduino project. Reversing ‘bridges’ have four switches (relay ...

Every time I log in, I’m presented with a list of new Blinky LEDs, Raspberry Pi accessories, Arduino ... Mega328 Transistor Tester Diode Triode Capacitance ESR Meter MOS/PNP/NPN L/C/R” in ...

We break down the essential component of modern electronics—the transistor. Transistors are the building blocks behind most ...

In an NPN transistor, the connection between base ... such as transistor biasing in a generation brought up on the Arduino or the Raspberry Pi. They are lucky enough to come out of their teenage ...

Let’s take a closer look at how NPN and PNP transistors work. There are two main types of transistor: bipolar junction transistors (BJTs) and field effect transistors (FETs). BJTs are made of ...
