The Final Project:
Saiki and I decided to make a rave bot. It looks like this:
And here is our video.
The Process:
We didn’t really know what to expect going into it. We knew we wanted to make a theramin with an ultrasonic sensor, so we started from there. We tackled the breadboard first. And we ended up with:
First, we connected the sensor, the speaker, and the potentiometer, which controlled the volume. Then, to add the digital component, we added a button and the changing LED light into the mix. If you press the button, the LED starts looking like a strobe light. There ended up being a lot more wires than I expected. See below:
Which brings me to my favorite and most challenging part of the code. The entire code is on Saiki’s post since we coded everything on his laptop. But I took a screenshot.
We kept fiddling with the ‘if’ values until we got the effect we wanted. After all that, we put the circuit into a box and started spray painting everything to get that graffiti rave effect. All in all, this was a super fun project. Honestly, the sounds the speaker was making doesn’t sound that different from the noise music scene today. I came away feeling proud of what we accomplished.
