Class 4: LED Matrix Programming
Includes the following topics:

• How to wire a Neopixel / WS2811 / WS2812 LED matrix 
• How to translate XY coordinates to a linear array index (via FastLED's XYMatrix)
• How to use & experiment with the FastLED noise algorithm, and how to animate noise across a matrix using color palettes
• How to animate pixel / sprite / 8-bit art on an LED matrix
• How to use the FFT / Fast Fourier Transform algorithm to obtain sound spectrum data from Circuit Playground's sound sensor 
• How to visualize sound data: creating an interactive sound spectrum analyzer using the LED matrix

Class 3: Sensor Input.

Includes the following topics:

• How to use the Circuit Playground's light sensor
• How to use the Circuit Playground's sound sensor
• How to use the Circuit Playground's 3-axis accelerometer
• How to use the Circuit Playground's capacitive touch sensors
• How to computer a running average & self-calibrate sensors
• How to change lighting patterns in response to sensor data
• Overview of how to use external sensors with Arduino

Class 2: More Advanced Patterns

Includes the following topics:

• How to increase or decrease brightness in code
• CRGB and CHSV colors in FastLED
• How to make animated patterns using RGB values
• How to use FastLED color palettes
• Gradient color palettes & PaletteKnife
• Arduino millis() timers, and how to use them
• How to use timers and randomness / beats / sines to make generative patterns

Class 1: First Light. 
Includes the following topics:

• What are LEDs?

• Programmable LEDs, including different common products (matrix, strips, pixel modules, neopixel rings) and how to power them safely. 
• Ohm's law, circuits, current, and resistors. 
• How to use FastLED sketches. 

Hi Folks! 

I hope you're enjoying the class. We had a request to include some of the links we mentioned in the office hour, so we wanted to list them below!
