project that stores the entire state of the keyboard in one number using bit flags. if you look at the code, you'll notice the only sensing block in the project is used to write to KEYBOARD_STATE; the display only reads from that variable.
thanks to the Scratch Workaround Guide VII by _nix (https://scratch.mit.edu/discuss/topic/611582/) for the power operator workaround keyboard key sprites are from https://github.com/q2apro/keyboard-keys-speedflips/
