Supplies for Chapter 8
This chapter is all about sensing location,
so most of the new parts are sensors.
You'll also reuse the radios from Chapters
6 and 7.

1 Sharp GP2y0A21 infrared ranger
This distance-
ranging sensor operates on 5 volts, and outputs a 0-5V
signal when it detects objects from 10 to 80cm away.
It's one of a family of infrared-ranging sensors from
Sharp. Available from many retailers, They are relatively
inexpensive and very easy to use.
