# A-OK: reconstructing a 433.92 MHz remote-control protocol

> A-OK implements the 433.92 MHz remote-control protocol used by AC114-01B controls for roller shades and projector screens. Arduino sketches capture 65-bit commands and transmit pairing, movement and stop commands; the README identifies tested motors and RF receivers.
