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 ...

If you are looking for an inexpensive, accurate, easy-to-use temperature sensor, then LM35 is an excellent choice. It has an accuracy of ±¼°C at room temperature and ±¾°C over a full −55°C to 150°C ...

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 ...
