摘要
采用单片机、555电路和数码管设计制作计数光字牌,具有加1与减1计数并显示和复位功能.从硬件和软件方面都取抗干扰措施,保证计数准确.工厂使用证明显示效果好,电路简单实用.适用于袋装等形状大小基本相同并有可能紧挨相连的产品计数显示.
Using Microcontroller Unit （MCU）, 555 circuits and digital tube to design digital counting light plate; This has plus or minus one and reset function. Anti-interference measures of hardware and software are taken to ensure accurate counting.It＇s proved that it has good display effects, simple and practical circuits in practical application. It is suitable for counting and displaying bagged products or other similar shapes and sizes which may be close or connected.
