I want to make automatic dog feeder, all i want is a circuit diagram.
What I want is somewhat like this.
I set time on alarm clock and as soon as alarm kicks in it should trigger a motor to unlock the door. So the challenge is to convert .4 v to 9 or 12 v. I need some what a relay or somethin. Pls help me with the circuit diagram.

Is this a school project? If so, we don't do homework.

Why not just buy an automatic feeder? They're available in different sizes and are reasonably priced. No need to re-invent the wheel unless you want a project.

Why mess around converting an alarm clock when you can buy a timer at any hardware or home center? Most of them come with at least two sets of clips so you could trigger it on and off twice each day if you wanted. Plug in a transformer of whatever voltage you need to run the gate or whatever you are going to use to dispense the food.
