基于單片機的廣告移動彩燈

摘要
    隨著電子技術(shù)的迅速發(fā)展，單片機得到了越來越多的應(yīng)用。本設(shè)計用單片機89S51結(jié)合LED（發(fā)光二極管）制作了一個廣告移動彩燈，它由一塊89S51組成，通過逐次掃描其中一塊的P2.0--P2.7口，從而依次實現(xiàn)彩燈輪流點亮、逐點點亮、間隔點亮。如果控制交流彩燈，可在P1端口加接繼電器或可控硅接口電路。它可以通過程序設(shè)計亮兩種顏色。本設(shè)計可應(yīng)用在廣告彩燈控制器、舞臺燈光控制器等領(lǐng)域。

Based on monolithic integrated circuit advertisement migration colored lantern
Abstract
    Along with the electronic technology rapid development, the monolithicintegrated circuit obtained more and more many applications. Here Iused monolithic integrated circuit 89C51 to unify LED (light emitterdiode) to manufacture a belt music broadcast function advertisementmigration colored lantern with the loudspeaker, it was composed by two89C51, through gradually scanned together P3.0--P3.2 mouth, judgedwhether had the pressed key to press down, unified the port scanningand the pressed key scanning, thus realized the colored lantern tolighten, to lighten, the gap point by point in turn in turn lightens.If the control exchange colored lantern, may affix the relay or thesilicon-controlled rectifier connection electric circuit in the P1port. This design's characteristic lay in with three foot's light emitter diodes has manufactured a running water colored lantern, it might through the programming bright two kind of colors. This design may apply in advertisement domains and so on colored lantern controller, stage lighting controller.
