Coin acceptor sending constant pulse signal to USB encoder
-
Hello, I'm having an issue with getting my coin acceptor to work correctly. I have a video describing everything here.
Please if anyone has any answers to why this is happening. I'm not an electrician by any means lol. But I e seen other people across the web getting this to work. And it seems like possibly a simple fix.
Apparently according to my research, the coin acceptor send out a constant output pulse until the coin is inserted, at which point it sends a high output pulse. I think this is why it's not working. Would I have to get a coin acceptor that doesn't send a constant output pulse. If so how would I find one and know how it differs from this one. Or....is it my power supply. Should I go for maybe a 1 amp instead of 2?

@mrmanguy do you possibly have any tech info on the coin acceptor? Like a spec sheet or something?
-
@mrmanguy also does the encoder register a short as a 1 (a pull down switch) or 5v as a one (pull up). It maybe that the output of the coin acceptor may be inverted for your encoder. i’m guessing that you don’t want to send any voltage to the encoder as the encoder is not designed to receive voltage from the outside in Besides it’s USB power.

@mrmanguy I watched a few videos and it is kind of confusing, but from what I gather, you can program different coins to send a number of pulses. If you want a coin to give 1 credit, you only need 1 pulse. And you want to have the nc/no switch set to no (normal open) so when a coin is inserted it closes the switch. The power supply amps don’t matter much here. I hope that helps

@lostless I don't know about pull down/up. I'm not that knowledgeable in tech to that extent. But I did see that someone else wrote a review for the same type model saying that he was experiencing the same problems. I found an actual functioning coin double door from x arcades and just decided to go that route. It seems to be more mechanical in the way it just bridges the connection. But I would like to see if there is still a way to get these cheap ones to work. It would be a neat to see how that would work. I e seen some people hooking there's us to ab Arduino and setting up counters. And I'm pretty sure others have gotten it to work

This is the video I watched. From my guess, it allows different kind of coins to give a number of pulses. But if you only program say a single kind of coin and do 1 pulse, that should work. -
@lostless the number of pulses are just to tell the microcontroller (or computer) which coins you are putting in. So you can set a quarter for 5 and a dime for 4 and so on. So when you set up an electrical piggy bank. The computer can tell which coins you put in. I'm guessing I would have to put some type of resisiter for this to work which is beyond my present capabilities. I went ahead and bought one off of X Arcades site. They have one with the microcontroller and stuff hooked up so all you have to do is Jerry rig it to your buttons or just connect it straight to the USB encoder. So hope it all works when it comes in lol
