Assistance Modifying Code

[chuco61]

my question here

I have these two script working perfectly on my Raspberry pi and Arduino respectively.

I am trying to add in two features to the code at this point.

1. Add a skip button that is tied to the Arduino and skips through the songs in the queue of the py code
   
2. Add a "play series of mp3 clips while the RPI is in an idle or inactive state
   

Where would be the first place to look to get this going, can someone possible help me code this?



Thank you!

• A lot of parasitic empty lines
  
• Un-indented blocks
  

Please, make your code presentable - I don't think you'll find anyone willing to read 400 lines of mess

I agree with volcano63, chuco61 - can you edit your post please so that your code is indented? I can then try on my RapsberryPi / Arduino for you..
