2. What are we working with?

3. How to Shine a display?
This type of display uses 7 segments to create the image and the 1 segment for the decimal point.
Each segment has it's own input for a high voltage and then the entire digit has a common ground called a common cathode which takes up a single pin

5. Goal
Have the display loop through a few letters then through all the numbers 0-9 and a decimal point.

6. Programming The Display

7. Display Code Initializing global variables Setup() Loop()
Create a constant for each pin and the associated segment of the display
Create a function for each letter and number you which to print, making sure you set to LOW each segment you don't want on
Make a function that loops through every letter/number with a 1 second pause in between
Setup()
Serial.begin(9600) starts using the Serial Port
Turn every pin to digital output
Loop()
Send a serial message that the program is starting
Call the character looping function
