What is KeyDuino
Keyduino is an Arduino compatible development board with built-in NFC (Near-Field Communication).
KeyDuino is the easiest way to build an NFC project with the benefits of Arduino.
NFC or Near Field Communication is a standards-based short range wireless connectivity technology that enables making transactions, exchanging digital content or connecting electronic devices with a simple touch.
NFC is compatible with hundreds of millions of smartphones, contactless cards and readers already deployed worldwide.
KeyDuino greatly simplifies the development of your NFC projects thanks to the simplicity of Arduino platform.
KeyDuino will be the bridge that helps you wirelessly interact with your environment, drive motors, unlock strikes, control relays, read from a temperature sensor and all thanks to built in NFC connectivity, right out of the box.
The KeyDuino development board is Arduino Leonardo hardware (with a few exceptions, see Q/A) and software compatible .
Since the KeyDuino is based on the Arduino Leonardo (ATMEGA32U4) all code that runs on an Arduino Leonardo can also run on a KeyDuino
The main use of KeyDuino will be access control. Examples such as accessing your home's front door, your drawer or even your car door are all easily realizable with the KeyDuino.
To sum up, The Keyduino makes replacing your keys with your smartphone, the NFC Ring or any proximity card, a reality.
Reading & writing the content of an NFC tag or establish a peer to peer communication between KeyDuino and an NFC smartphone is easy !
