综上所述，本发明是在玩具上安装光敏传感器，利用玩具的光敏传感器对智能设备上运行程序所提供的亮度变化信号进行采集，智能设备可以是手机或平板电脑等，进而对玩具的动作进行控制，即，能根据识别到的智能设备的触控显示屏亮度变化来驱动LED执行亮、灭或闪烁，或者驱动所述玩具振动，从而实现了智能设备与实体玩具之间的有效互动。本发明在玩具上设置光线检测电路、LED驱动电路的输入和电磁线圈驱动电路来实现对玩具动作的控制，直接将光线检测电路的输出作为LED驱动电路和电磁线圈驱动电路的驱动信号，具有电路结构简单，制作成本低、易实现的优点。
以上所述，仅为本发明较佳实施例而已，故不能以此限定本发明的范围，即依本发明申请专利范围及说明书内容所作的等效变化与修饰，皆应仍属本发明专利涵盖的范围内。
工业实用性
本发明是将智能设备与玩具组成一个互动系统，智能设备可以是现有的手机或平板电脑等设备，已经在工业上得到了实现，而预置在智能设备内的能够使触控显示屏显示出亮度变化的对应程序在工业上也是容易实现的。与智能设备进行互动的玩具则是利用光线检测电路来采集智能设备的触控显示屏亮度变化的信号，并直接将光线检测电路的输出作为LED驱动电路和电磁线圈驱动电路的驱动信号，来实现智能设备与实体玩具之间的有效互动；本发明的光线检测电路、LED驱动电路和电磁线圈驱动电路是采用光敏二极管、电阻、三极管、发光二极管、MOS管、电容和电磁线圈等普通电子元件来构成，本发明在工业上便于实现，而且由光敏二极管、电阻、三极管、发光二极管、MOS管、电容和电磁线圈制成的光线检测电路、LED驱动电路和电磁线圈驱动电路在工业上也便于加工。
