Put on your party hats, hit run (the triangular thing on the top of the Processing IDE). Different RGB LEDs may have different pin patterns.Īlso you have to change the /dev/ttyUSB0 in line 31 to point to your Arduino's port (something like /dev/name on Linux or com5 on Windows). If you have the Common Cathode type, you have to change int common_cathode = 0 to int common_cathode = 1 on line 26 in the above source code.Īlso, you should probably use some basic program to check whether the variables like redPin1, bluePin2, etc. Change the song.mp3 string in line 36 to the name of your mp3 file, or rename your mp3 file to song.mp3.Īs I said before, I'm using the Common Anode type of RGB LEDs. Copy a mp3 song into the folder (/path/to/musicLED) where you saved the Processing sketch. Processing will copy it into a folder with the same name. > Add Library.ĭownload the source code (musicLED.pde) from the bottom of this page and open it using Processing. If it's not there, install it from Sketch > Import Libraries. Then go to Sketch > Import Libraries and check if Arduino (Firmata) is on the list. Open the Processing IDE if you already have Processing installed, else install it.
