last week a friend of mine who is not so familiar with arduino and electronics needed a vu meter for his school project. he supplied me with an arduino and an lcd. the rest was up to me. i searched around the internet to find code for it without succes. many people show a vu meter but dont give any tips or code. so i started to write code myself.
this code is not complete. it does doe strange things when you disconnec the audio jack. also when no ignal is found it gives full barrs(which i like)
what is complete is: -nice looking edges -signal smoothening -loading screen(can be removed just for show) -arduino shield-like connectins(just plug it on and ready)
1 thing i ask from you. i am a youtube partner. i dont get many vieuws but the money i get from it always goes to projects like this. if you just watch the video below and check out my channel for my other video's it would be of great help to me.
thank you for reading this and enjoy the code.
