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 ...

Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced circuits using multiple seven-segment light emitting diode displays. Here is a simple, yet useful ...

What do you do with 144 7-segment displays ... hand-coded lookup tables for each digit. The lookup tables are stored in ROM, saving precious RAM on the Arduino. A clock wouldn’t be any good ...

[rhoalt] had neither, but he did have several 8 LED Neopixel rings lying ... which uses the Neopixel rings as 7 segment displays. Each digit is made using one pair of Neopixel rings, stacked ...

“I’ve built a digital clock made out of 144 seven-segment displays controlled by an Arduino Nano. The segments are controlled by 18 MAX7219 ICs which can control up to 64 individual LEDs or 8 ...
