555 Timer - Timer

This project was undertaken as a potential submission for the 555-contest hosted by Hackaday in 2021. At its core this widget operates as a cooking timer, implemented with 276x 555's. The user sets the time on a 7segment display (in minutes), and the timer counts down (in base 10) until the counter is depreciated. Once all the 7segment display is all 0's, the timer triggers a temporary alarm to notify the user.
