I'm trying to build a circuit that uses two switches to turn on and off pump. I had it all set up on breadboard and it works fine, but when I created PCB it is not working properly. The pump does not turn on only when I unplug the power and plug it back in. I'm using 12V 1200mA power supply with LM7812C regulator for the pump and LM7805 for the Atmega328P microcontroller. This Microcontroller has the Optibot loader from Arduino. I tried to test with with the simple led blink test, and all my LED would blink the way they should. but I can't seem to get the motor/pump turn on.
I have attached PCB drawing ( need to clean it up little) and schematics.
PS: I'm new to electronics. Be nice.
