请注意：套件不带电池，需要自己在我们店里购买，谢谢！

光控LED小夜灯套件 

参数：

供电电压：直流3v（配套7号电池盒，电池需自己购买）

板子尺寸：2.5*2.5cm（焊盘已喷锡，焊接方便，质量好）

LED颜色：配套5MM透明发白光，可自行购买别的颜色替换

功能简介：

光控小夜灯，白天有光线LED不亮，到了晚上光线暗时，led灯就自动亮了(可接继电器模块做光控开关控制其它电器)，白天情况下，用手遮住板子或者光敏电阻，LED也亮。需要注意的是，光敏电阻要处于较暗的环境才可以亮，不要像下面的用手遮住，会漏光。增大270K电阻，可以增加灵敏度。

注意事项：

1.注意板子上的元件从体积小的开始焊接，然后再焊接大的。

2.个别元件如电阻电容等暂时缺货，我们会发其符号电路原理的他附近值的元件代替，蓝色的金属膜电阻的可能换成灰色的碳膜电阻发，灰色的碳膜电阻的也可能换成蓝色的金属膜电阻来发。是一样的效果。

3.焊接好后，请自助调试，焊接没出错的话一般都可以成功，如果焊接失败，本店只能协助您查看问题所在，我们不能保证您一焊接就能成功，这个也是为什么工厂生产线上需要维修工的原因，电子产品因为静电击穿，因为电源正负极接错烧坏，因为虚焊，因为元件焊接错位置等等等等原因出现问题的几率很大，别总说板子线路是有问题的，这个板子卖了几万人，出问题的就几十个人！我们尽力做到良好的售后服务，尽力协助各位朋友完成制作。因此，当遇到制作出来的成品没有达到我们所描述的效果时，请先不要急于给我们评价，记得联系我们的售后服务，我们会竭尽全力。谢谢合作，祝大家购物愉快！
