Practical Arduino: Break down the Bytes from your Arduino to your Computer

Here we're showing what happens when you convert analogue data on your Arduino and send it up the USB cable to a program on your personal computer. We've got a Java program that will then graph the data. But we can also look at the USB data using CoolTerm, RealTerm, etc. We go over the math needed to convert the bytes into regular numeric values.

This process is super important in engineering data logging applications.
