Hello,
I'm currently using the Arduino UNO Wifi Rev2 board with the Adafruit basic fingerprint sensor with Socket Header Cable, this one: https://www.adafruit.com/product/4690
I downloaded the Arduino library that was written for the sensor and hooked the wiring up in several different configurations (including the correct way), but continue to get the message saying the sensor could not be found. I have a meeting upcoming with a professor about the issue, but I am posting here to see if anyone can help before then.
I also have looked around and have seen forums on different sites saying the UNO Wifi board doesn't work with the sensor, is this true?
Did not find fingerprint sensor :(

Re: Did not find fingerprint sensor :(
It looks like you have a 3.3v only sensor. See https://learn.adafruit.com/adafruit-opt ... ep-3082673.
