Arduino Powered Musical Christmas Lights
It worked, the wiring took a while. I made an out of focus video, but, it's still fun.https://youtu.be/2mpHC0AZgNE
I got the port mapping worked out with some work, the Arduino documentation for the port mapping is not correct for the mega 2560, but I found http://harperjiangnew.blogspot.com/2013/05/arduino-port-manipulation-on-mega-2560.html which has correct mapping and it looks like I'll have to use some of the high pins to find 8 contiguous pins in the same port. Should be smooth sailing the rest of the way.
I did it with a mega. The big change from the uno code is the pin numbers for the port manipulation. Once I figured that out it was all smooth sailing.
Thanks for sharing! I'm going to try this out with my mega and an 8 relay module that I have. I'm thinking that I'll wire a 1/4" audio input to the protoboard rather than cutting up a cable. Would I just drop that in front of the capacitor?
