I've just finished my diy darkroom timer!

I had a not working Philips timer so i decided to make one using an arduino board, a relay and some knobs..
The first two knobs set the seconds , the coins are touch buttons to eliminate any vibrations and i've put a built-in speaker that beeps at decided intervals (for this i used an old earplug headphone).
I'm currently finalizing the code but it's already working great and precise ))
