ELECCIRCUIT.COM : ELECTRONIC CIRCUIT PROJECTS IN SIMPLE WAYS OFLEARNING
WHY SHOULD YOU BUILD AN ELECTRONIC CIRCUIT? Because there are three reasons as follows:1# Useful Learning
ELECTRONICS is some of the physical science, engineering, technology. Also, I have been teaching my children Electronics. But, they seldom understand the theory. It is boring and hard for them to understand. You maybe like my children. Ancient people said that I hear and I forget; I see and I remember; I do and I understand. It is true. So, I believe that creating an electronic circuit is good learning. It helps us easy to understand it. * HOW TO BUILD ELECTRONICS CIRCUITS 2# ADD VALUE TO YOURSELF! We know that electronic circuits insides the appliances around us. Normally, we do not need to understand their operation. But skill in electronics is very helpful. If you have electronics skills. Others will be impressed with you.Why?
Because you can solve the problem for them. Imagine: An electric fan of your friend is broken and the weather isso hot in summer.
To buy a new one is not a good idea. But to repair it is hard for those who do not understand Electronics. If you do, you will be able to repair it easily. That is changing the capacitor of the fan which costs half a dollar. In this way, you can solve the problem quickly and help your friendsave money.
