For my third Arduino project, I wanted to connect an ultrasonic sensor to Arduino and create a visual effect with Processing. I wanted to hide a picture in front of another and have image in the front change in opacity as the object got closer or farther from the the sensor. This is an example of how this would look like:

I failed at doing this project as connecting Arduino to Processing is harder than it seems and I haven’t learned how to do that yet. I want to come back to this project and make it work when I learn the skills to do it.
