I am currently working on my car dashboard, and I got an idea.
What I want to make, is a dashboard vault.
Let me explain what I want to make.
I would like to add 4 push buttons in my dashboard.
Hooked up to my Ardiono Diecimilla.
I want to make a specific combination of the 4 pushbuttons, in a specific order to make it interact.
Let's say, I want a code for example: 1423.
That means I have to push the buttons in that order.
But now, I want to make it open a box in the dashboard.
Perhaps I want a 'spring' in a cover which pushes the cover up.
But I want the cover be released after entering the code.
So when I close the cover, it has to be pushed into a lock machanism, and when the buttons are pushed, and the code is correct, the mechanism has to release the cover.
But how can I make this. (What kind of lock mechanism can I use, and how can I make it interface with the Arduino?
Another idea I had, is to make a 'drawer' slide out of the dashboard when the buttons are pushed.
(Like a DVD drive does, but then a bit bigger)
I would like to use this for documents like my drivers license etc.
I assume I have to motorize this, and hook a small motor to the arduino.
Also for this kind of project, I would like to have some information about how to realise this...
Can anyone help me in the right direction for these 2 projects?
I think it would be very cool to create.
Most of VWs and Audis, use a small spring loaded motor to open the fuel cap, they only have 2 wires, and then there is a small "hook" on the fuel cap, so you can close it again, without activating the motor.
But just about any magnet valve, will do the job.
[...] and then there is a small "hook" on the fuel cap, so you can close it again, without activating the motor.
Thats exactly what I want in my first example, with the cover.
On correct code, only release the cover, so I will pop using a spring for example.
After that, the lock has to be closed back after it's popped, so I can manually push down the cover to 'click' it back into the lock.
(So that when the code is pressed again, it will pop again)
Sounds easy, but I don't know where I can find any lock machanism which does what I want...
And about the combination code, how about you did it like this.
5 buttons, a b c d, and a OK button to confirm code.
The code is 1752
Then you have to press a once, b 7 times, c 5 times and d 2 times, and then the OK button. this is how the radio code works on newer VW radios.
