I have tested Ben on his current knowledge of Python.

Demonstrate how an Arduino is designed and works.
- What can be done with microcontrollers vs. full size computers.

Continue with build and program of analog inputs and PWM outputs.
- Modify the program for output to color LEDs-

We kept exploring how complex shapes emerge from the repetition of simple patterns.

Hardware setup to input X and Y inputs from joystick and output to two different color LEDs.
Write the code to perform the read (for calibration), the to control the LEDS

How to scale analog inputs to a 0-5V (0 - 1024 bit) range-
How the resistive light sensor works-
Defining the required circuitry-

Learn how Arduino reads analog inputs.
Design a circuit to input a 0 - +5V voltage and convert to a binary number.
Write the code to control the LED lighti based on the analog input value.

What computers use to represent information
Binary numbers, bits, and bytes.
How different information is represented in bytes

Understand difference between analog input and output.
- A/D conversion on analog input.
- D/A conversion on analog output (faked by PWM).
- What is PWM and how is it used?
- Make a circuit and program that uses PWM output to dim an LED.

We went back to exploiting the RGB color display.
