ABSTRACT
In order to reduce the amount of paper used for environmental protection, we made this attractive signboard to reduce the amount of paper used and tree felling. Also, the infrared remote control can be used to change the designed text and graphics, thus achieving the goal of convenience, time-saving and safety. This hardware production mainly utilizes the characteristics of the persistence of vision principle to generate images. Using 8051 series (STC12C5A32S2) SoC, it allows a row of LEDs to flash different LEDs at different times. The principle is similar to that of a movie's continuous picture. Together with the high-speed rotation of the motor, it creates the persistence of vision to hold on the human eye and displays the screen we requested.
