Okay. Basically I want the android app to be able to recognize that a coin was inserted into the coin collector before it allows the user to use certain functions of the app.
However I am unsure what would be the best way to pass the data from the coin collector to the Android app. My currently train of thought is to have the coin collector connect to an Arduino board which would then connect to the android app and send the input through that connection.
I was wondering if anyone knows of a better way to achieve this, or whether this is an acceptable/standard solution.
Thank you in advance!
