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 ...

We want to use four 7-Segments LEDs controlled by ... pin 33 of the board (the common pin) to the Arduino GND signal. At this point, all works fine again, the only difference being that every display ...

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 ...
