Very good but please can you make the alarm continue going longer until it has been reset. Otherwise, one quick beep will not wake you up. Please help us to include this feature

Now this is an actual How-To's/Tutorial for newbies, where a total noob can actually see how the parts are wire and soldered together and can just follow it instead of trying to read an schematic you have no idea about..

THANKS.
