This week in lab, we were instructed to do an exercise involving one way serial communication. We were allowed to pick any two input sensors, so we decided to do ours utilizing piezzo buzzers since our final project will possibly involve using these sensors.
Procedure:
First, we hooked up a simple circuit with two piezzo buzzers. Next, we opened Arduino and created a program that would read the results from the sensors in the serial monitor. However the reading that this type of program was giving was just a string of random numbers, which was not helpful for our purposes. So we used CoolTerm to help make sense of the garbage.
Next we imported this to Processing. We used the bytes that were pulled in from the sensors and the Arduino to create a graph.
Here is a screenshot and a video:
