RFID演奏音乐
引言：Arduino做的各种应用广泛被开源硬件爱好者喜欢。今天给大家介绍一个互动性强的arduino RFID乐器，适合放松娱乐，这个项目利用了RFID和MP3模块，把从RFID采集的数据通过MP3模块播放特定的音符，从而带来适合少儿娱乐的互动音乐游戏。 https://www.bilibili.com/video/BV1Q44y167uh?share_source=copy_web 第一步：展示内容用的这个模块这个是RFID的连线图第三步：硬件搭建
序号 名称 数量
1 arduino uno 1
2 rfid模块rc5221
3 rfid tag 7
4 DF MP3模块 1
5 8欧喇叭 1
6
第五步：发一些硬件的图片。让人有个直观的认识
从arduino串口找到每个tag的编码。具体是打开arduino-实例文件-rfid-cardread，打开cardread文件并上传，之后用RFID扫描tag，然后在串口里查每个tag的编码。在串口看扫描tag后的tag编码
第七部：连线图第八部：代码部分的设计
