Conditional Programming in Arduino IDE | Detecting Sensors

Conditional Programming is programming involving the use of boolean conditions (TRUE or FALSE) to direct the flow of a program.

Let’s consider a case, how would you program a LED if I want you to turn the LED only when a switch connected to digital pin 2 is pressed otherwise it is turned Off? Got it! you have to check the state of the switch and execute a certain code when it is pressed and another when it is not pressed.¬†

This is known as conditional programming.

Before diving into deep, we have to clear some concepts. In this lesson, we will first learn about various operators, if-else-if statement and later on, using these concepts, we will program the above-stated problem.

Let’s get started.
