arduino nano
arduino mega 2560
arduino uno
尽管arduino产品线很丰富，nano，mini体积也很小，但是总归放到电路板上感觉不是那么回事儿，学习过一段时间，这两天终于下定决心，放弃nano直接上atmega 328P，搜罗各位大神神贴，各种坑后终于烧录成功(arduino uno + arduino as isp),烧录成功后的代码我先贴一下：

芯片电路组成
连接图
注意事项：
1 6条线都要进行连接不能省略
2 一定按照上图pin10 连接328P reset（我开始一直用uno icsp rst脚去连接，所以老也搞不定）
3 可以先拿自己手上现成的nano跟uno连接刷引导程序，成功后再上芯片
4 IC插座，节约成本的神器
5 8和22,7和20 21之间不连接，也能刷入成功（之前电路板画错了，所以也没拍照片）
