Working with serial

This week we started working with the Arduino and serial.

Here I have two potentiometers and a push button:

Using one sensor, I uploaded the example code to display the sensor value in different ways:

We learned how to write to three sensors and view the data in the serial monitor:

Next we learned how to use the arduino to send values from an analog sensor via serial to the p5 IDE.

My favorite friend the sliding 10K pot:


The arduino code to write the single sensor value in binary to serial is pretty simple:

Here is the p5 sketch working with it. It is printing the serial value as text:

Next I mapped this data into a graph:

It was really exciting to get the two potentiometers and the push button to talk to p5 at the same time via serial:
