I’m trying to build a simple application for my school presentation.
I used Processing 3 to create an interactive animation, you can see it here: http://g.recordit.co/2pcd1pZL2C.gif
I also want use Arduino Circuit Playground (right and left pushbuttons) to change the color or the background. I want ACP to send a signal every time I press a button, then Processing will catch it and transform into an action.
The problem is that I don’t know how program Arduino to send the signal every time the button is pressed. Can I get some help with my project?
