We used ultrasonic sensors to create a virtual grid that can detect and graph movement
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.
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.
With blood , cardboard and electrical tape, and the arduino and sensors.
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.
We are proud of making our first HARDWARE hack! We used an arduino in conjunction with sensors and a computer to create life!
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.
Probably nothing, but we had a blast making it.
We used 4 ultrasonic sensors, a ton of wires, an arduino, a laptop, C++ , python, matplotlib, and of course, blood, cardboard and friendship!
