Thanx for the input.
Unfortunately I want it the other way around. I want power to be given after timer expiration, and no power during timer operation. :wink:
Oops. For LED D3, it was my mistake when redrawing schematics. Thanks for pointing that out.
For the fuse, I thought only about protecting the circuit. Since the load (3 water pumps) are plugged directly into "the wall outlets", I didn't believe I should need one for the load. To protect the...
Well here it is. Hope this fans out.

Since the original schematics had a 4700 ohm resistor in series with the base of the transistor, and eblc1388 changed that to a 10k ohm, I know not which to use, so I didn't identify it. Shouldn't cause any trouble though...
Wow, never expected all this help! THANX
Thanks. Fun to see a fellow Quebecer, a rare occasion for me. Salut 'sti! :D
Sorry 'bout that. I am planning on wiring each output pin to jumper pins to be accessable from the outside of casing, so I didn't bother putting them in the schematics (would...
I cant really say I understand it myself, not even close.
I dont know if I can do this but here is the webpage I found this on:

Maybe a few answers can be givin there.
D3 is supposedly used as a visual indicator to set the timer to wanted delay. D4 supposedly...
This is my first time here, so Greetings To All.
Just so you know, I am new at this, I have made a few projects before, but I learn as I go along and my only repository to electrical knowledge is the internet. I have a basic knowledge on how to use certain parts and that is about it...
