Piezo speaker

A piezo speaker converts an electric

signal into sound. Polarity is not

Microcontroller (µC)

A programmable device which can perform various tasks.

We have pre

-

programmed it so that it will play musical notes or it

will generate the sound of a cricket. This device is has a polarity.

Watch the position of the notch.

Transistors

E B C

C B E

A transistor is an amplification device. By means of a small current,

a much larger current is controlled. Transistors come in two

flavours, NPN and PNP

-

types, depending on the polarity. With this

kit, you receive a BC557 (PNP) transistor. A transistor has 3 pins:

Base, Emitter and Collector.
