Design of Intelligent Control Billboards Based on MCU
With the inconvenience of the existed billboards on the market, this paper built a new kind of system made by hand-held transmitter to send remote control signals to change the ad content displayed on the billboard. Remote control device with STC89C52 microcontroller core, and display systems use the C8051F020 microcontroller to drive the integrated LCD module. The communication between the two using RS232 communication protocol to build smart billboard system. Through simulation, the design can easily achieve the function of changing the display content by intelligent remote.
