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.

Quick, how do you wire up an SPI bus between a microcontroller and a peripheral? SCK goes to SCK, MISO goes to MISO, and MOSI goes to MOSI, right? Yeah. You’ll need to throw in a chip select … ...

Experimental, use with care. The SPI protocol is a "standard" for serial communication, however there exists many variants. This document only describe the four modi typical used in the Arduino ...

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.

This little guy, while simple in nature, acts as a fully functional (and portable) keypad on the go! It comes with two main programs, and it connects easily to your Arduino. It can be used to: 1 ...

The Gesture Keyboard is a device that translates gestures into letters. It’s made by an Arduino Pro Micro, an HC-06 module for Bluetooth communication, and an MPU-6050 accelerometer.

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 ...

Recently, virtual keyboards are also in use but for every single keyboard, the user should remember the arrangement of keys in order to enter different characters.} {Remote-based gesture keyboard is a ...

Different keyboards are available in the market, with variations in size, layouts, programs, and functionalities. Recently, virtual keyboards are also in use but for every single keyboard, the user ...
