In the Arduino board, digital outputs from D2 to D8 are used to drive segments (a to g), and digital outputs D9 to D12 are used for the digits (D0-D3) of the 4×7 LED display. Note that here the ...

I did an 11×132 display using the three 11×44 ARGB LED matrices that scrolls a lot more than 600 characters using an Arduino Nano. This is easy peasy piddly. Yeesh.

Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can ...

[Martin2250] has been working on a spinning disc style POV display. He’s posted his progress up on reddit. This hack is a great example of using what you have at your disposal. [Martin2250] i… ...

Open the Arduino software and paste the Arduino code (the text in the box near the bottom of the post) into a new sketch. Click Sketch > Verify / Compile to make sure the code is properly in there.
