This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

The code is available on Dropbox. The code is extremely simple due to the use of the Parola library and a MAX72XX library. We’ve seen a number of projects based around this chip.

For his latest project, [XTronical] has recreated the classic displays from Dr McCoy’s sickbay with an Arduino Nano and a 2.8 inch LCD display.

Click Sketch > Verify / Compile to make sure the code is properly in there. Save the file and then attach the Arduino to your computer with the USB cable. Click File > Upload.

Although Arduino's programming language is based on C++, you won't be able to use all of its commands. But, you can still use objects in Arduino's IDE, which are a fundamental aspect of C++.
