Cards Dispenser CTD-200 controlled by Arduino

Projects General Guidance
1

Hi, i'm new with arduino, and I have no background in electronics.

I want my arduino to be able to dispenser one card at a time. I looked at the product page,

http://xcp.com/model-ctd-200-12v-card-dispenser-clone.html

I'm guessing that CTD-200 is what I need, but I don't know what is pulse TTL, and I have trouble understanding the tech description.

Based on this clip:

I'm guessing that I need to hook it up to an external 12V source, and use an arduino to give it a HIGH signal, however I have no idea this is correct or not. Or is it a switch, and I need a relay to trigger it?

I want to confirm which method works first because I don't really have much money I can play with, so I don't want buy it before understanding it.

Thanks
Cynric

A TTL signal is a 5v signal as you would get from an Arduino.

Reading the description, looking at the cost and your questions, suggest to me you need a lot more study before you would be able to successfully use it.

Based on the pinout sheet

http://www.vendapin.com/Adobe%20files/CD-200PinOuts.pdf

Im guessing that 1,2 are the power supply.

3 is the common ground.

4 is the 5V signal for dispensing a card

5 is the 5V signal to reset the machine

6 i have no idea

7,9,11 I'm guessing are the LEDs for the status

8,10,12 are the status signals I could read into my arduino

Are any of these guesses correct?

Why not build your own card dispenser module?

Connect a motor to a (rubber, car...) wheel that will shift out the topmost card of the deck. That's how many printers dispense paper sheets for printing. Add a spring below the card deck, that presses the remaining cards against the wheel.

Um...just seems like a lot of work, I don't have access to a hackerspace or a laser cutter.

My guess is i'll probably need an infrared switch to make sure i dispense only 1 card at a time ?

Paper pickup in a printer uses the rubber wheel to push the paper into another roller that then pulls the paper. The pusher motor stops once in the puller roller. This way only one page is moved at a time.

Use one motor and wheel to start it and another to eject. This will then enable one card at a time.

I found a cheap one that is made in China which I can play with first and try to get it to work, well even if I fail at least I'll learn something from it.

If that fails, then I'll try and build one myself.

Thanks!
