Alternating LED Flasher in Arduino

Before the coming of new year 2019 I have decided to write a code to perform alternating LED Flasher using Arduino UNO it is fun because I was able to apply my knowledge in C programming rstand the concepts and principle of Arduino. I hope you will find my work useful. May the new year 2019 brings us new learning experience.

I am currently accepting programming work, it projects, school and application development.

LED Blinking in Arduino Uno

In this article I would like to share with you a very simple program that I wrote to make the LED or Light Emitting Diode blink using Arduino. I am just learning how to write a program using Arduino and I feel it is a very fun way to spend spare time.
