From the project

A small electronic device that counts how many times the button on the device has been pressed

This repository contains the project files for an electronic button clicker. A button clicker is a small electronic device that counts how many times the button on the device has been pressed. It features an additional button that displays the count on the device to save battery power. The maximum count on the device is 999,999, and it has a button debounce time of approximately 10ms. The counting mechanism utilizes BCD counters, and the count is displayed on 7-segment displays using a BCD to 7-segment IC. The device itself has dimensions of approximately 4 x 1 x 0.65 inches and comes with a…
