Alarm System

Organized by: Eric Peterson, Melissa Strait, Dmitri Skjorshammer, Henry Lew

Darryl Yong asks: Can you put numbers on the supplies needed? (est for 35 students, and decide how many groups, how many per group, etc.) I love the youtube vid. I can definitely pick up parts from Radio Shack, but for the quantity we need, i need to order via internet, so please let me know asap.
