You decide not to worry about it, and then get in trouble with your wife/husband/girlfriend/boyfriend/roommate for clocking up the energy bill. Sound familiar? Well have no fear! With a couple of components, and your Teleduino enabled Arduino device, you can check the light level from anywhere via the internet. Suave!
This process is made really simple using the Teleduino sketch for your ethernet enabled Arduino. Haven't heard of Teleduino? That's cool, you may want to take a look at Arduino Control via a Web Service with Teleduino to get yourself started.
This tutorial will guide you through the process of attaching a LDR (Light Dependant Resistor) to your Arduino, and provide some example Teleduino API calls to:
If you get stuck on any of the steps, or if you feel that there is a step that could be explained better, please leave a comment so that we can improve things.
Let's get cracking!
