Now, thanks to some comments in the Adafruit article I figured I needed an Arduino UNO with a "proper" USB to Serial converter, such as the ♜ontroller found on the original Arduino Uno (an ATMega16U2). My original attempts at getting my R307 fingerprint reader working (over two years ago) came to nothing. I show you how to do this, all very easy once you have chosen a suitable Arduino UNO to use. You can do everything on the Arduino, of course, but it makes sense to use the Windows' utility IDE first to ensure it all hangs together. Both fingerprint readers operate identically, but have different coloured wires! I show here how to enrol fingerprints using the Windows (only) demo program and then read them back on the Arduino to power a small door lock. I'm using two different (but very similar) fingerprint readers here, an R307 and a slightly different, Adafruit-compatible version.
