This is an example sketch for our optical Fingerprint sensor
|
|
|
|
Designed specifically to work with the Adafruit Fingerprint sensor
|
|
----> http://www.adafruit.com/products/751
|
|
|
|
These displays use TTL Serial to communicate, 2 pins are required to
|
|
interface
|
|
Adafruit invests time and resources providing this open source code,

|
please support Adafruit and open-source hardware by purchasing
|
