Hi Guys,

Not sure if this in the right sub forum, if not mod can replace it to the right one.

I have a microcoin, and bin trying for a while now to get a proper signal about what coin is going through. Following the specs its an open collector, but whatever i try it is not giving me the result i wanted.

Anyone that can push me in the correct way about reading the open collector.

The ground i get from the arduino it self.

The other two signals, and sample code; anyone :slight_smile: ?

Technical data, pin layout etc etc: http://www.coinmech.com/images_products/images_supporting/1953.pdf

Thank you in advance for your time,
Mike

Connect all the grounds together, and use pinMode(pin, INPUT_PULLUP) with the open collector output.

What about connecting a LED in series with a 1 kohm resistor to Vcc (and to the "unknown open collector output") and see what happens?

awesome! the _PULLUP made it work:)
