Getting On Board Accelerometer

It took me a bit to get the on board accelerometer to work. I tried following the first library, and was having difficulties. I tried using this second tutorial and had issues with using both the Serial and IMU parts of the library. After more soul searching, I found this other tutorial which actually used the first library. As it turns out, however, I didn’t need this at all for the first lab…

Intro to Asynchronous Serial Communications

The first lab brought little trouble.

Serial Input to P5.js

The second lab

Following the tutorial I was able to get the sensor value printing to the screen. It took me a few tries — I was using the wrong input value for my analog read, my output wire was connected to ground instead of the output, and I had problems with the code (I restarted and went through more carefully). After all this, I finally printed out the sensor value:

And with the addition of the graphing function I was able to get the pentiometer graph working as well!
