Hi guys! 👋

when I was working in a robotics and artificial intelligence competition called RAINO CUP, we had some building models that needed some lighting for every layer and due to my passion for music and optical stuff, I decided to make a VU Meter for them by inspiring of other projects without too much information (that's why my code in like noobies 🙂). most of the VU meters on the web use an extra circuit for the microphone and leveling the sound but thanks to esp8266 we can do it with fewer components by using UDP protocol. now we can make everything musical if it has levels(one time I made a musical servo and it's so easy to make) I think this project is too easy but it can come in handy sometimes and make awesome stuff.

1.ws2811/ws2812(or anything that have many states

2.esp8266

Choose one of the codes in ESP8266_CODE and change it to your desired network credential then upload it.

connect your pc to esp wifi then open VU_meter.exe and play your music

although it's an easy code but it can be more intresting to have an android app or reacting to microphone ( i use "listen to this device" option in windows) and ...

(after these videos motions get smoother by making level steps from 1/10 to 1/100 with a few changes in codes)
