Arduino教程及实例--详解串口通信失败（程序上传失败）原因及解决办法

近期有朋友使用Arduino IDE时反馈在做声音传感器设计的时候，上传程序一直不能成功，一直提示上传错误。在Arduino教程中有没有相关解决方案呢？我们来看下
主要错误码如下：
avrdude: st500_getsync() attempt 1 of 10: not in sync: resp=0x00
avrdude: st500_getsync() attempt 2 of 10: not in sync: resp=0x00
avrdude: st500_getsync() attempt 3 of 10: not in sync: resp=0x00
avrdude: st500_getsync() attempt 4 of 10: not in sync: resp=0x00
avrdude: st500_getsync() attempt 5 of 10: not in sync: resp=0x00
avrdude: st500_getsync() attempt 6 of 10: not in sync: resp=0x00
avrdude: st500_getsync() attempt 7 of 10: not in sync: resp=0x00
avrdude: st500_getsync() attempt 8 of 10: not in sync: resp=0x00
avrdude: st500_getsync() attempt 9 of 10: not in sync: resp=0x00
avrdude: st500_getsync() attempt 10 of 10: not in sync: resp=0x00
上传项目出错
以上错误出现的原因主要有以下几点需要引起注意：
1.arduino在IDE下载过程中没有复位；
2.串口脚（0、1）被占用；
3.USB转串口通信不稳定；
4.bootload
