Here's an analogue drawing I'm making using the data from my ultrasonic sensor. It takes a long time with a pen and ruler! So Max/MSP is a good solution. Here's a low-quality photo of the drawing:

I searched around the internet for some tutorials on how to make animated drawings, and I found a really good series focused on jit.lcd. However, I still need to find out how to draw lines in a non-randomized way using my data from the ultrasonic sensor. I haven't been able to find the answer via google, I think because my question is too specific and I have a pretty clear way that I want it to look. So, feedback on how to change the objects and messages to that end would be much appreciated!

And here are the four tutorials that taught me how to build the patch:

Here are relevant artworks that I feel could be inspiring for this class:

Timo Arnall, Immaterials: Light painting WiFi, 2011

Katie Paterson, As the World Turns, 2010

Taavi Suisalu, Distant Self-Portrait, 2016

Here's a patch-in-progress, now that I was successfully able to get my ultrasonic sensor readings to appear in the Max console. I'm also including a screen recording of the Max print feed, so you can see what's going on – I see that the console is breaking up the lines of data into smaller pieces (which I can imagine is simple enough to fix). For example, in Max/MSP, the word "distance" is broken up between several lines, and so are the numerical figures. Here is an example of how the same data shows up in the Arduino serial plotter. Just a note, I have included the word "distance" to also be printed, just to reduce confusion about values.

15:41:05.887 -> Distance: 68.54

15:41:05.958 -> Distance: 68.54

15:41:06.063 -> Distance: 50.18

15:41:06.171 -> Distance: 50.17

15:41:06.278 -> Distance: 50.98

15:41:06.387 -> Distance: 51.39

15:41:06.459 -> Distance: 51.37

15:41:06.563 -> Distance: 50.93

15:41:06.667 -> Distance: 50.52

15:41:06.769 -> Distance: 50.52

Now that I'm thinking more of the aesthetic exploration, I would be interested to have this data converted into a digital drawing that changes over time, so I suppose that would be a video or animation. I'm particularly interested in how a drawn line in digital space can be infinitely thin (unlike a pencil line, which is defined by the material), and so I could imagine playing with what are known as "space-filling curves" that approach infinity – for example, Peano curves or Hilbert curves. Here's the wikipedia page for an overview of what's behind them:
