I have been trying to make an Arduino Kitchen Timer for quite some time now. After lots of troubleshooting I have managed to get it almost working! So far the design is that a normal LED Bar Graph counts up when a button is held, then each LED turns off every five minutes. The code so far is as follows:
The Fritzing sketch is as follows, but please note that LEDs are not used!
The issue that I am struggling with at the moment is not one of Hardware, I know that it all works and is in theory wired correctly. At the moment I am noticing that when the 6th LED bar lights up there is more of a delay, and that the timer is not counting past 5 mins. I have also not wired in the Piezo speaker as I don't have on.
I hope you can help me :) Ari
