How to Solder Correctly

Heat Sink

What is heat sink?
Why we need heat sink?
How it look like?

A few people I ask about this and the answer is because senior tell about it and other. The main I want to tell they don't know why they want use it actually. They just follow what other say. First let me say about the function heat sink itself.

Voltage Regulator

Function Voltage Regulator is the main supply to the circuit project. Most of the IC only need 5V to function. If less than 5V, IC will NOT function and if the voltage more the 5V, IC will BROKEN. That why we need this Voltage Regulator to convert and maintain our voltage supply was 5V.
