I have children (a boy and two girls).
I always have in mind to connect my hobbies to my family. It not always turns the way I'd like, but not this time. For precious moments time-to-time I make presents myself. Like the repurposed radio for my mother for Christmas.
During the last weekend was one of my daughter's 14th birthday. She is moving to party age soon. What would be better than something with lights connected to music.
This project is just a simple, floor standing VU meter, using a microphone board, Arduino Nano, and WS2812 LED strip. Quite a simple one.
I had issues with the microphone board. I bought all together 7 different kind. It would be a long story the troubles I had with those (so not writing it today). Finally I choose one from DFRobot. Mainly because the two 3mm mounting holes, what perfectly fit into my design.
I don't want to write to much about it, so the pictures.
The finished "product" (first, just because it looks better when sharing on social media. 😂)
How it is work (It is just her sisters yelling. I'm afraid, if I use some music on it, one of the YouTube's piracy dickheads ban it). It also has yellow and red, but unfortunately can't be seen on the video:
All of the elements (mainly code and the 3D design) can be found in this git repo. It also contains other VU meter related things, what is "work in progress" and not connected to this project:
