Lab: Two-Way (Duplex) Serial Communication
*
Project Documentation
Initially this was going to be a drawing tool.
1) I discovered the EMG sensor placed on the chest picks up heart beats.
2) Instead of moving a circle around on screen, I used the value to change the size of an ellipse.
Code in Arduino:
Values in the serial monitor look like:
89,15
91,14
90,14
90,14
90,13
91,15
92,14
92,14
90,13
90,11
92,15
86,14
89,12
89,11
91,13
90,12
90,12
...
In p5, the size of one sensor placed over the heart changes the size of a white ellipse on a black background.
Possible directions to take this project:
- Connect to infrared camera to track position of body and move projected shapes accordingly (Def possible!!)
- Work with bluetooth capability of Nano to reduce number of wires & technical difficulities during performance (tho personally I like the aesthetic + it works dramaturgically)
+ Need to flesh out interactions between different sensors, or if it uses only one sensor, then the pulse needs to be fleshed out in the output and performance

Earlier tests that somehow led to this.
