this week’s lab has been about exploring serial communication, specifically between a variable resistor (in this case the potentiometer) and the computer.

first, i programmed the arduino to read the values coming in from the potentiometer which actually gave me the data in BYTES causing the data to come out looking funky like this.

second, i tried to open up a serial port using terminal on Mac OS X but for some reason it kept returning a value that said “permission denied”.

finally, i programmed processing to read and write using the computer’s serial ports.

and used the x-position on the graph to visually graph the potentiometer’s values.
