A couple of weeks ago Apple announced the new iPhone 5s with Touch ID, a fingerprint identity sensor that replaces the need for a conventional PIN number or password. It got me thinking… wouldn’t it be cool to make a lockable toy box with fingerprint access for my son’s toy car collection.
At the heart of the system is an Arduino Uno and an Optical Fingerprint Sensor from Adafruit. The box uses a standard hobby servo as the latch to lock and unlock the lid based on the fingerprint detected.
Secure your project with biometrics – this all-in-one optical fingerprint sensor will make adding fingerprint detection and verification super simple. These modules are typically used in safes – there’s a high powered DSP chip that does the image rendering, calculation, feature-finding and searching. Connect to any microcontroller or system with TTL serial, and send packets of data to take photos, detect prints, hash and search. You can also enroll new fingers directly – up to 162 finger prints can be stored in the onboard FLASH memory. There’s a red LED in the lens that lights up during a photo so you know its working.Related
