This is a test with the Jetson and an Arduino using Jupyter labs Notebook!
Because of the errors I kept getting, it took quite a while to code and fix but this is just a video to show that I was able to get a connection via serial to the Arduino.
Overview of what happens:
When you type in "Y" or "y", it sends a "YES" byte to the Arduino which interperets it and turns the light on. Vice versa with "N" or "n" but this time, turning the LED off.
