Introduction:

This article helps in creating simple Arduino project that is perfect for the beginners.

This basic project will help in understanding how to set up the Arduino software.

No prior coding experience is needed to undergo this project. Students will learn

about the working principles of LED and how to programmatically control LED lights

using Micro controller + Bluetooth via Arduino & Android App along with academic

relevance. A clear understanding of how the LED light glows when the command

is sent from the Arduino Android App and how exactly wired and wireless

communication happens between microcontroller and Bluetooth.
