Rustambek's first-ever hackpad

I wanted to make hackpad with built-in OS. You control OLED display with keycaps or switch the mode to control PC. Sadly, I ended up with simple project that can only interact with PC not with OLED display. However, I haven't given up hope. When I recieve parts, I will make some modifications in code in order to try reaching my goal

Overall design

What's special?

• You can play games conveniently (e.g. snake game) that can be controlled with arrow keys
• RGB led will blink when you tap a key
• OLED Display shows instructions on how to use the hackpad

Features

• RGB LED will blink green if Up, Down, Right, Left arrow keys or Enter key are pressed
