DIGITAL I/P AND O/P WITH ARDUINO ALONG WITH USE OF SERIAL MONITOR IN ARDUINO IDE

This is a small but very useful exercise for providing and obtaining digital i/p and o/p from an Arduino uno development board simultaneously. In this particular demonstration, we have used a micro push-button switch as input and a LED as output. But, the same logic can be applied with and digital i/p and o/p device as per the necessity of a project.
Along with this, we are also showing how to print something on the Serial Monitor of Arduino IDE software which is the visual interface for Arduino development boards.
The sketches are as follows:-
