应该在之前的探索中,我们可以找到一个上传的button 不过我们在点击它之前,可以先检查一下我们有没有配置好相关的一些信息。 我们是通过arduinoIDE来和我们的arduino通信的,arduinoIDE需要我们给它我们的arduino的型号(这里是arduino uno)和端口(电脑应该会自动识别出来)。在设置好这些后,我们应该就可以开始上传了。

于是谷歌了一番,发现还真有人做了将音乐可视化的东西,那就是音乐节奏灯。说的简单点就是LED灯光颜色亮度等随着音乐的节奏而发生变化,看了下他们的实现方法有很多,不过大都比较复杂,而且灯只能够做节奏灯也比较浪费,于是我便动手做了一个既可以当作普通台灯使用,又可以随着音乐而闪烁的动感节奏灯,一举两得。
