Student creates binary USB keyboard with two keys and OLED display
An American student has made a binary keyboard with only two keys and an OLED display. The input input can be sent to a PC via the USB port, so users can actually type, although tapping the keyboard for entire novels will require a lot of keystrokes.
The keys have two modes, according to the project’s page on GitHub. In addition to binary input, the keyboard can also enter regular numbers, although only the numbers ‘1’ and ‘0’ are involved. You can keep track of the input on the OLED screen and after eight characters it converts it into a letter, number or symbol. The keyboard can be connected to a PC via a USB port.
The BinaryKeyboard is a project by American student Chris Johnston, who didn’t really have a compelling reason to build it, but he thought it would be fun to do. The keyboard has a knockoff from an Arduino Pro Micro for processing the input, while the keys come from a Cherry MX Clear keyboard. The OLED screen is an SSD1306.
