Last active Oct 22, 2015
This is a sketch that allows the ATtiny line of micro controllers to interface with the GT511-C1/3 fingerprint sensor from Sparkfun. The advantage of this sketch is that it requires no libraries and thus works on any board that can be programmed with the Arduino IDE. The sketch initializes the connection with the sensor, turns the sensors in-bui…
