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 ...

This Arduino project implements a multi-counter system with buttons, LEDs, and a 4-digit 7-segment display using the FunShield board. Each button controls its own counter, and the current counter ...

const int a = 8; //For displaying segment "a" const int b = 9; //For displaying segment "b" const int c = 4; //For displaying segment "c" const int d = 5; //For displaying segment "d" const int e = 6; ...
