Pre-lab Tasks:

1. Draw a schematic diagram of the dual digit display circuitry and draw a picture of your proposed breadboard layout. Explain how the time multiplexed display works.
2. Draw a schematic diagram of your completed ADC circuit and draw a picture of your proposed breadboard layout. You need not redraw the display circuitry, simply denote it as a block within your drawing.
3. Rewrite the ADC program you created earlier so it converts a constant reference voltage into a 6-bit digital number and outputs this number to the dual digit display you designed. Describe how this program differs from the original program.
4. Predict the converted voltage as a function of the reference voltage and plot this relationship.
