Program a small Arduino Using A bigger Arduino to Display a Scrolling Text Without a Library.

An artistic alarm clock that uses and array of 7-segment displays to display large digits in a unique way.

Hi, In this post I will show you how you can build a diy seven segment display with the help of a 3D printer, an Arduino and some LED bar...

I have made this project using an old CD player's DC motor, Arduino Pro Mini, LED, a Hall sensor, and some other electronic components.
