The electronic component what we learn is diode. Diode has many types which are ligth emitting diode(LED)and zener and so on. Diode has many function. For example, diode can make sure the direction of the current flow. Diode can also be emitting light by using LED.
We have learned how to use apparatus to test the diode. We also learned how to diffretiate the positive and negative pin of diode. En. Redzuan also show how the number that we can see on daily life like elevator that tell you which floor are you is make up by diode. This number function diode is called 7 segment diode which composed by 8 diodes. It has a common cathode or anode and the other pin are opposite charge pin.
