Can anybody advise me if the circuit attached will function as required.
The external timer supplies a 6 volt signal to the relay coil for between 3 & 9 seconds, this in turn drives the 12 volt motor for the 3 to 9 seconds & it also charges the 220uf capacitor.
At the end of the 3 to 9 seconds, the Piezo buzzer should continue to sound for a further approximate 80 seconds via the N channel MOSFET.
Any help appreciated.
