diy 16路led电子萤火虫（stc版/开源） -ag真人试玩平台

游泳的鸟儿 · 发表于 2023-8-23 17:49:37

这个是1年半前做的了，今天才想起来没发过，发上来。在坛友的代码上适当改动，把6led的增加到16led，用贴片stc15w408as控制。

sop-20封装的单片机焊在转接板上

0603的led两头焊漆包线

焊16个，并点亮，确定每个都能亮

准备microusb

木塞上给microusb开口

装入瓶中的效果

点亮

你这不能飞，我找找，见过油管有个老外做了个飞起来的,似乎是用zvc感应电的

手工牛批的要做个记号，有空了慢慢看看

感觉铜线用的有点粗

mhtlov · 发表于 2023-8-23 23:52:55

有规律点，好看

ccbw · 发表于 2023-8-24 02:44:07

不错。挺漂亮的

sweetrong · 发表于 2023-8-24 07:35:30

建议加一个震动电机，随机震动

bafjdn · 发表于 2023-8-24 08:31:31

谢谢分享学习一下

有创意，感觉漆包线确实有点粗...

天使之音 · 发表于 2023-8-24 13:24:08

估计夜晚效果更漂亮！
