I made this Arduino 8 bit binary led counter as a solution for one member from Arduino forum. He asked if somebody can make a project that displays a decimal number in 8 bit binary format using 8 leds ...

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 ...

[Alex] needed a project ... control all 128 LED’s with just seven bits, but it was too slow for him. His solution was to control the multiplexers with counter IC’s. The Arduino can just ...

All by itself, a calculator based on an Arduino isn ... Bertović] of Volos Projects has a nice board that, of course, looks like a calculator. There are 16 keys and an LED display.
