Waves are very extremely straight: WAVES
Description:
We used ultrasonic sensors to create a virtual grid that can detect and graph movement
Inspiration:
The ultrasonic sensor looked like a cool sensor and we had two of them. We also experimented with sensors in the past and found this one cool.
What it does:
If a user traces a specified shape in the box the sensors detect there movement, graphs it and gives them a score as to the accuracy of their tracing.
How we built it:
With blood , cardboard and electrical tape, and the arduino and sensors.
Challenges we ran into:
Waves are not straight. The sensors we used use waves to detect distance, so they don't calculate vertical distance exactly, which created a lot of seeming abnormalities in the data. The wires we used where a bit unwieldy so they got unplugged quite a few times which caused a few issues. There where a lot of moving parts in the code, animating the graph, transferring and translating the data, which took some effort to get the timing of right.
Accomplishments that we're proud of:
We are proud of making our first HARDWARE hack! We used an arduino in conjunction with sensors and a computer to create life!
What we learned:
Waves are not straight. But also how to use the arduino much better now and how sensors work. Interrupt pins are a thing apparently. We also learned a great deal about how to program with and how to set them up.
What's next:
Probably nothing, but we had a blast making it.
Built with:
We used 4 ultrasonic sensors, a ton of wires, an arduino, a laptop, C++ , python, matplotlib, and of course, blood, cardboard and friendship!
