I recreated this project from Fritzing in my circuits.io project then on the arduino itself, it all works fine just how I wanted it.
The concept behind it is:
You plug it in and the time is set to 00:00
You can adjust the time to the time now let's say 22:46
You can put in an alarm to wake up let's say an hour later at 23:46
The piezo beeps in stops, so not continious.
So now my question is, how can I add a led that flickers on the same rhythm as the piezo (when the alarm goes off)? Can someone help me in my circuits.io project?
An update/edit would be great! I'm relatively new to all of this.
Thanks a lot!
