I am trying to control a coin dispenser (ICT - International Currency Technologies) through arduino and running into issues. I'm not very experienced in electrical components and I think my connections are done incorrectly.
I should control dispensing coin via single pin, setting it low for ~10 milliseconds.
This is the cable connection specification
the 12V VIN and ground is coming from external power source. I connected the external ground also to arduino ground. And then PAYOUT_ON pin from hopper goes to pin 6 in arduino UNO
When I set the PAYOUT_IN pin (pin 6 on arduino) to LOW, it starts dispensing coins, but it doesn't stop when I set it to high again. Is there some additional component I should add to my circuit maybe?
When I power on the coin hopper, then the PAYOUT_ON pin is already at 5V, so not sure if I can override it to LOW directly with arduino at all? Sorry if dumb or confusing question, I'm not very confident in circuits at all
Thanks in advance.
