avcom Posted May 7, 2014 Share Posted May 7, 2014 Hi,friends! I want to build a simple electronic machine: 1.The user inserts a coin. 2.He chooses from the screen menu some options. 3.After the user had chosen,he gets a ticket from the machine. That's all! The machine includes PC,coin acceptor(NRI G18), from a vending machine,printer. So my question is: How to connect the coin acceptor with the PC and the software of the machine,so the machine starts only after the user inserts a coin?May be I need a PCB/controller/? Thank you,Stan,Bulgaria. Link to comment Share on other sites More sharing options...
orsd Posted May 8, 2014 Share Posted May 8, 2014 hello, and welcome. now, there are many ways to do this, i will list them from easiest to hardest Also, if you can give me more information on what you are going to vend, i can better help you. method 1: print out the papers cut them up use a sticker machine like this to vend them http://beavervending.com/flatpak.asp this method can only accept one type of coin and will not accept bills, and wont give change. method 2: set up something like this http://www.instructables.com/id/Open-Bitcoin-ATM/ method 3 step one: get a cheap pc step two: get an arduino http://www.arduino.cc/ step 3: use a coin mech like this http://www.twistedquarter.com/index.php?main_page=product_info&cPath=10_57&products_id=948&zenid=b9tvclhabs6stgrdhamnj1c496 step 4; get a bill validator: http://pyramidacceptors.com/trilogy-series/ they have one for the leva, get the 12 volt pulse one. step 5; wire it up and progam it, this may help with the wiring http://www.instructables.com/id/Open-Bitcoin-ATM/ tip; set up the bill vaidator like this: if coin is one pulse, then the bill as multiple pulses equivalent to the values of the coins, for example in the usa a 4 quarters equals one dollar, so the quarter would be one pulse and a dollar equals 4 pulse step 6: hook up a printer optional: instead of steps 2-5, get this http://www.waferstar.com/en/PULSE-PC.html this method doesn't give change method 4: get a pc get an MDB bill validator like the pyramid tech one and MDB coin mech, get this:http://www.waferstar.com/en/MDB-PC.html then program it this enables change giving hook up printer Link to comment Share on other sites More sharing options...
