螺旋槳時鐘
指導老師:王佳盈   組長:朱芳賢   組員:郭彥廷、陳漢庭
本專題之目的在於使用AT89S52晶片與LED燈,透過程式碼按照一定的週期,使其配合LED燈的旋轉閃爍跑出所想要的文字或圖形,完成時鐘。
這個時鐘是藉由旋轉跟閃燈速度所造成視覺殘留形成的,閃燈與旋轉速度兩樣都必須配合才能正常運作,其中原理就跟有時候盯著正在跑的汽車輪框會出現類似靜止的錯覺一樣。
這個時鐘原本只是一排 LED 燈,但將它裝在馬達上旋轉後,它便會慢慢形成一個圓形的指針時鐘,不但指針是真的會動,而且還可以自定輸入文字,時鐘便會有文字跑馬燈效果,真的是很炫又實用!
不過可惜的是,這只不過是個完成度很高的 DIY 產品,目前還沒有量產。不過搞不好不需要多久,就可以在市面上看到它囉!
The purpose of the topic use AT89S52 chip and the LED light flashes ran through the code in accordance with a certain cycle, with LED lights rotating the desired text or graphics to complete the clock.
This clock is formed with both visual residues, flashing lights and rotating speed must tie in to the normal operation by rotating with the speed of flashing lights, the principle is similar to which you stares at a running wheel that appear the static illusion.
Before, the clock was just a row of LED lights, but when you installed in the motor rotation, it will gradually form a circular pointer clock, not only the pointer will move, but also can customize the input text, the clock will be marquee text , it's really special and useful!
But unfortunately, this is only completed a high degree of DIY products, there is no mass production. But they might do not need long, you can see it in the market.
我們決定將壓電陶瓷晶片和鞋子做結合。
