Driver for the Lectrobox Keypad Shield.
The shield is a combination of hardware and software that makes it simple for your sketches to access the keypresses from the included 16-key keypad. The keypad can either be mounted directly on the Arduino or connected remotely using a standard Ethernet cable. The shield communicates with the Arduino via TWI, using only the SDA and SCL pins, and does not consume any digital inputs. It is compatible with both 8-bit and 32-bit, 5v and 3.3v Arduinos. The hardware package includes a shield, a keypad, and a small RJ45 interface adapter for remote keypad mounting.
This library is compatible with all architectures so you should be able to use it on all the Arduino boards.
To use this library, open the Library Manager in the Arduino IDE and install it from there.
