Isn’t it time for a full Arduino-compatible keyboard? [ELECTRONOOBS] thinks so. This 41-button Arduino keyboard PCB is a stepping stone to his next project, a pair of two-way texting machines.

The Arduino uses a shift register to interact with the keyboard’s 8×10 matrix, and the sketch translates any serial data it receives into the keypresses the clone is expecting.

You will need a traditional computer to write Arduino sketches. The Arduino programming environment is written in Java and will run on Macs, PCs, and Linux machines.

Technical Details and Components The keyboard was built using an Arduino board together with a fuel capacity of controllers, which is then connected to a Raspberry Pi mini computer.

Robofun Create has built a fully functional keyboard using Staropramen beer cans, demonstrating once more that the potential of systems like the Arduino and Raspberry Pi is only limited by the ...
