自制16×16 LED点阵屏

1、自制1616 LED点阵屏LED汉字显示屏广泛应用于汽车报站器，广告屏等。LED之所以受到广泛重视而得到迅速发展，是与它本身所具有的优点分不开的。这些优点概括起来是：亮度高、工作电压低、功耗小、小型化、寿命长、耐冲击和性能稳定。LED的发展前景极为广阔，目前正朝着更高亮度、更高耐气候性、更高的发光密度、更高的发光均匀性，可靠性、全色化方向发展。所以今天就为大家介绍如何制作16*16LED汉字点阵屏。先看原理图：准备工作：还没加跳线：焊上154 ：为了走线方便 我将154焊在万能板的背面。焊上16根数据线。大功告成：效果：另外附上我自己做的学习板的图：自制的ISP下载线：自制的5V电源板：程序如
