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.

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

In particular with reference to this project:

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

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

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



As shown above.

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

As shown in the circuit.

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

That should be OK.

Quote
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.

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

Are you having trouble reading the circuit?

Quote
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.

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

They refer to the digital pins on the Arduino.

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

It is ground, all those points are connected together.

Use a big copper spike.

I don't think you connected the grounds, Dave.

Ground is one of the terminals on the arduino bord. It is marked GND.
All points with that triangle must have a connection to that point.
So join all the triangles together and then connect that to the GND pin.
