Money counting machine with coin and bill storage

Project information

In this project, I want to build a machine that counts Romanian banknotes (lei). The device will recognize bills of 1, 5, 10, 50, 100, 200, and 500 lei. After identifying each banknote, the total sum will be updated on a 4-digit 7-segment display. Every time the reset button is pressed, the total sum will be reset to 0 and the back door will be unlocked. As long as the reset button is not pressed, money can be inserted for counting. The money will be stored inside until the reset button is pressed.
