Q1... What is the voltage and current is your door strike

Q2... I am having trouble seeing where the prototyping board connects to the id-12 could you please help me out

Q3... I am also having trouble seeing how the buzzer connects up could you please help me

Q4... Could you please tell me if the transistor that i have will work. Here is the link: http://www.jaycar.com.au/productView.asp?ID=ZT2468

Q5... Is that a diode just behind where the door lock connectors are if so could you please tell me what diode i need

Q6... Could you please tell me what resistor or resistors i need could you please tell me

Q7... Could you also please tell me where everything goes on the prototyping board if you could do that it would be very much appreciated

Q8... could you also please tell me what D8, D7, etc.  mean

My door lock uses 24V.
Thanks for asking.

Cheers,

I think this question was addressed at me, based on various personal message I have got recently. :)

In particular with reference to this project:

12V. Not sure of the current. Still, it's the current of your strike that is important, right? A few hundred milliamps from memory.

As shown above.

As shown in the circuit.

That should be OK.

Q5... Is that a diode just behind where the door lock connectors are if so could you please tell me what diode i need


As on the circuit. I used a 1N5822 (Diode Schottky 40V 3A) to protect the circuit from the coil.

Q6... Could you please tell me what resistor or resistors i need could you please tell me


Are you having trouble reading the circuit?

Q7... Could you also please tell me where everything goes on the prototyping board if you could do that it would be very much appreciated


Wherever you want to put it, it isn't critical.

Q8... could you also please tell me what D8, D7, etc.  mean


They refer to the digital pins on the Arduino.

would this transistor be better

Looks about the same. Looks like it has the pull-down resistor already installed.
