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 ...

From a simple electronic toothbrush to complicated robotics systems, DC motors are present everywhere. In most of our previous Arduino projects, we have used these DC motors as actuators and ...

Based on the knowledge developed in the previous tutorials, we now start the study of this important electronic component. We have thus created a PNP transistor. Figure 1: A PNP transistor. The size ...

It is made from a sandwich of three layers of semiconductor material: two layers of n-type material, which is a semiconductor doped with elements that provide extra electrons, and one layer of p-type ...

Ever since the development of the first working transistors in 1947, the electronics industry has experienced tremendous growth in numerous ways. For instance, transistors allowed for the ...
