LED摇摇棒的单片机实现

Research on Shake LED Based on Single Chip Microcomputer

LED摇摇棒是如今流行的一种玩具,在各种聚会、节日中均见得到它的身影。LED摇摇棒是是基于人的视觉暂留原理,通过分时刷新16个发光二极管来显示输出文字或图案等信息。输出信号频率的控制通过单片机来实现,用摇动传感器检测当前摇动状态。当进行摇动时,由于人的视觉暂留原理,会在发光二极管摇动区域产生一个视觉平面,在视觉平面内的二极管通过不同频率的刷新,会在摇动区域内产生图像,从而达到在该视觉平面上传达信息的作用。

Shake LED is a kind of popular toys, we can say it in all kinds of party and festival. It is based on the principle of persistence of vision, and controls 16 leds to display the output text or design information through the single-chip microcomputer. We control the output signal frequency through the sing]e chip microcomputer and use the shaking sensor to test the current state of shaking. When shaking, due to the persistence of vision principle, It can produce a visual plane in the light emitting diode shaking area. It will produce images in the shaking area through the diode refreshing in different frequency in the visual plane. So as to achieve the visual plane in the role of conveying information.
