I want to make an interactive projection installation with Arduino. I am quite familiar with MadMapper but I am a super newbie to Arduino. I understand that MadMapper has FIRMATA that allows you to connect with Arduino. There is a basic tutorial (https://www.youtube.com/watch?v=muosra5uIAs) by MadMapper that explains well about that. However, I am totally at loss as to how to actually use any other sensor or interactivity other than what's shown in the tutorial. For example, I want to control the movie clip in the MadMapper by sound input in Arduino. I can find the Arduino code sample to use the microphone but I have no idea how I can modify that to work with Firmata. I have been searching but I have found only ONE tutorial (mentioned above) with the subject which is hard to believe.
Do you have any idea where I can find such tutorials or lessons? What do you recomend? Do you recommend that i study Arduino coding from scratch, then learn to manually code? Please advise. Thank you so much in advance!
