The team a Zunkworks wanted to build a device for people who can’t normally use a keyboard and mouse. The Bluetooth Morse code keyboard is what they came up with. This build gives the user full control over the keyboard and mouse using a single button or a sip & puff interface.
The project is build around an Arduino ProMini, an FTDI breakout board, and a Bluetooth module. It’s a fairly simple build, but the meat of the project lies in the code. Every keystroke and mouse movement is only a few button presses away.
Like the USB Morse code keyboard we saw last year, this project also translates the dits and dahs into characters that are available on a keyboard. In fact, Zunkworks even used the code for this USB morse keyboard as a reference. With only one button for user input, we’re reminded of Stephen Hawking’s computer interface. This project might be an improvement on Hawking’s system because it allows control of the mouse cursor.
