PROJECT 6 – INTELLIGENT COOLING FAN
In this final project, you will use all the measurements you took from the previous
project, and build an intelligent cooling fan. This cooling fan will only turn on when
things are warming up, and it will turn off automatically when things cool down. As a
final modification, you will also add some code that estimates how much longer the
fan will run for and display a count-down on the screen.
