Arduino #7 - Demonstrate PWM

Dim an LED...that is....demonstrate Pulse Width Modulation (PWM) - (Boxall Project #3 - pp 47-49)

There are three tasks for the PWM project

1. First, follow the Boxall sketch and dim a simple LED (use up to 6 single lights - there are 6 PWM digital outputs on your Arduino Board)
2. Then, get a 3-color (Red-Green-Blue) LED and demonstrate dimming bright/dark AND color change. One of my former students - Vivien Boe. Class of 2015 - posted a sketch on how she implemented the 3-color LED PMW in the video (above, right)
3. Finally - demonstrate color change WITHOUT dimming. This is the hardest of the three exercises, and requires you to plan and write an original Arduino sketch

Create a single post for this project on your student web pages for all THREE tasks. Reflect on how many and what kind of debug errors you had (hardware, schematic, sketch/software, or reading/understanding the assignment). Include a photo of your hardware; three 10-20 second videos demonstrating each intended applications; and Google Docs with copies of your Arduino sketch(es) for each instance that you generate custom code.
