Lab 0 - The Bike Light

Due: 12 (Chris’s Section) or 13 (Gui / Oscar’s Section) September 2013

Description

In this lab you will build a bike light.  Your goal is to set up LEDs such that pressing a button will switch the light between several different modes: all off, all flashing; all on; and “bouncing” lights.  There should minimally be four modes, and three LEDs.

A second phase of this lab, to be unveiled Monday 9/9, will build upon what is presented here.  We suggest trying to complete the lab by Monday so you can focus on the extension, and writeup, for Thursday.

⬜  5 @ Current Limiting Resistors for LEDs (roughly 500Ω, or 1kΩ)
