I think this question was addressed at me, based on various personal message I have got recently.
In particular with reference to this project:http://www.gammon.com.au/forum/?id=11283
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.
Q3... I am also having trouble seeing how the buzzer connects up could you please help me
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.
