Logic is a process of systematic thinking to come to a definite conclusion for getting real practical applied solution.
For example, when a teacher teachers you about how to implement the rules, syntax and important steps related to logic, while creating the logical programming structure, he can only teach you how to use the OR, AND and NOT logic.
Now it is your views, ideas, expressions, direction of thinking to implement all these things correctly to come to a definite conclusion so that you will get some systematic logical program like in Arduino, etc. and also get good result out of it.
We shall try to understand this with the help of a simple example…
Suppose I want to blink an LED on and off alternately using simple Arduino platform.
