Weekend Projects - Hot/Cold LEDs

Complete instructions for this episode of Weekend Projects can be found at http://makeprojects.com/Project/Hot-C...

Combine an Arduino, an ultransonic distance sensor, and some common components to build a classic "hot/cold" project. Once assembled, we'll walk through the software "sketch" loaded onto our Arduino, and experiment with three variations of the "hot/cold" theme, all the while using the same circuit.

I thought I was going to learn to sense temperature with an urtrasonic. :(

Waking up the PC with a distance sensor is a really nice idea! :D

You can use for your old garage. Lets you know how far to pull in so you can safely close the garage door
