I am converting an old vending machine into a box you can sit in and i wanted to hack the vending machine touch pad to be able to change the lighting patterns of LED strips i want to mount inside the box. the touch pad has 21 buttons, and a 12 pin attachment. (i attached a photo of it). I am a newbie at electronics and it was hard to even find a place to ask a question like this. Any help will be appreciated.
