A simple, yet effective wireless virtual keypad replacement to the standard hardware keypad usually used in Arduino project builds.

These membrane keypads can also be used with Raspberry Pi, PIC and AVR microcontrollers.

Includes the buttons: 1,2,3,4,5,6,7,8,9,0,A,B,C,D,#,*

This app transmits the characters as strings over a Bluetooth connection.

Includes demo sketches to get you up and running quickly plus hardware build guides for absolute beginners. These guides focus on the Arduino Uno with a HC-06 Bluetooth module although other setups should work fine.
