【Arduino 动手做】多色带图案：DIY RGB 立体声 VU 表
在这里，我向您介绍一款由 Arduino 供电的立体声 VU 表，具有模式、颜色、亮度和音频灵敏度控制选项。完整的 Arduino 代码链接如下。您可以花 2 美元为本机添加蓝牙音频连接功能（指南 - • DIY 蓝牙 RGB VU 表 |多色色灯).此外，您可以将此装置制作成一个令人惊叹的角灯（指南 -• DIY 音乐反应式 LED 落地灯 |Arduin...).享受！。如果您觉得此视频很有趣，我恳请您通过点赞和订阅来表达您的支持。您的参与不仅推动了频道的发展，而且为我创作更多引人入胜的内容提供了巨大的动力。衷心感谢您的宝贵支持！
