Perhaps if it can be done on an Mbed then someone might even make a ZX81 emulator on the Arduino. We’re great fans of the ZX81 here at Hackaday, for some of us it was that first computer.

Code Functionality Keypad Input: The code reads the input from a 4x4 keypad matrix. Keyboard Emulation: Based on the pressed key, the Arduino sends corresponding keystrokes to the computer. Keystroke ...

This Arduino BASIC interpreter will make a really fun one-day project if you’ve already got the parts on hand. [Usmar A. Padow] put together an Arduino Uno, SD card, four line character LCD, and ...

The unique beer can keyboard has been created to act just the same as a standard keyboard, but instead of keys 44 beer cans have been used, that when touched create the input required.

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 ...

To make that actually work, Robofun paired an Arduino board with some capacitive controllers for the base, and connected that to a Raspberry Pi that linked the keyboard to the TV.
