Macro keyboard based on ATmega328P.
Keyboards are one of the most important input device for a computer. A standard keyboard has more than 100 different keys for different purposes. Yet sometimes it feels like it'd be great if there're some programmable buttons to execute certain commands or a particular set of key combination. Keeping that in mind I have designed this Ardu Keyboard, a programmable macro keyboard based on popular ATmega328P microcontroller.
- It has 9 push buttons connected in a 3 by 3 matrix format.
- ATmega328P DIP IC in bare minimum configuration
- A USB 2.0 male connector
- CH340C USB to TTL converted IC, to talk to the microcontroller over USB.
