I need to use some OPs and I'm not sure what kind of input I need now. Regarding to the colors of the OP-pin, I need an analog pin. But is this a hardwareconnection or not? Otherwise I thought about using a digital input pin with hardwareconnection enabled. If it is a real hardwareconnection, there shouldn't be any difference.
Seems to be an easy question but I'm a little bit stuck here.
