I am relatively new to arduino, and have been making use of it in various capacities to support children with disabilities. That being said, I've never really learnt the basics and predominantly try and cut and hack apart code examples to get the result I need (I will eventually go back to the beginning to figure what i'm actually doing).
I am trying to build a basic sound board with 9 buttons, each playing a different song that is loaded onto a SD card.
I have used this guide as a basis and managed to get the device working perfectly with a start, stop next song button.
However, I need to edit the code to have 9 assignable buttons - each allocated to a specific song (eg. song 0001.mp3, 0002.mp3) that are loaded onto the sd card.
What parts of the code will need altering in order to do this?
