Lab 1: Intro to serial communications
I connected my Arduino, which had two potentiometers and a pushbutton, to the Terminal. Here is the output, which is changing when I change the value of the potentiometer connected to A0 port.

I then mapped the 0 to 1023 potentiometer output values to 0 to 255.

When I changed Serial.println() to Serial.write(), I got garbage values when I turned the potentiometer.

I got p5 to read input from my potentiometer, as you can see with the "sensor value" reading.

I was able to get a graph to work with code in p5, reading the potentiometer output
I was able to get the p5 code to convert any value from the potentiometer into readable output, and here's what the graph looked like when I did so:

I was able to get the LED to turn brighter or dimmer by pressing the keys 1 to 9 on the keyboard.
When I dragged the mouse left to right and back, I was able to make the LED brighter and dimmer.
