Binary Keyboard

Nette Spielerei von Chris Johnston: „A two-button backlit mechanical keyboard that types ASCII values, one bit at a time.“ (via JWZ)

Each byte can either be typed from most significant bit to least significant bit (left to right), or least significant bit to most significant bit (right to left). This is set before uploading to the board. After all 8 bits have been entered, it will type out the ASCII value equivalent of that binary valiue. The Pro Micro has native USB support, which means it acts just like any other keyboard.
