Also, in the code you have a buzzer connected to pin 9 - if I wanted to alter the ending so that a servo motor was triggered to turn something off could I just replace the buzz function with the servo code?

NICE JOB BRO!
I have a project. Control time for tv
NEEDS:
1) FORMAT HOURS:MINUTES
2) TRIGGER. (ADD +30 minutes to counter descendent)
Adding +30 to current time
3) RELAY (active when timer active )
And maybe a buzzer alarm last 30 secs
I gonna cheak out your cide. But i really need help for point 1, 2 (im very noob)
This gonna be used whit a coinselector (like old school arcades)

on a breadboard would the crossing wires be the same row? Do I need the capacitors or will this work with just the resistors and buttons and display wired

I'm a bit confused by the connection of the resistors and capacitors - is there a different diagram or a better picture you could send me personally?

Amazing! Nice video. I have a question. how can i save the time that i set, and add a button, when I pressed the added button, the saved time will display.
