ATMEGA328红外遥控电动窗帘-制作DIY-原理图-程序-测试视频-转载自国外网站 - 圣源电子制作

该项目是“电动窗帘”远程控制。它是由单片机ATMEGA328与Arduino的BootLoader，电机驱动L293D（我所用的外部二极管L293B，因为我无法找到L293D），红外接收器的TSOP 1738年，直流电动机从旧的打印机和其他小零件。控制它，我用红外遥控器，从宝联电视调谐器。该软件允许移动的帷幕从左至右回，或应采取的步骤。在去年PEG（窗帘导轨）连接一块小磁铁，两个簧片接触交互，对铁路的两端。最后PEG是把它连接到一个线，其中一方的电机和其他卷轴移动。

源代码是写在Arduino的。我用红外遥控器解码代码NECIRRcv图书馆。
