Cheapo Arduino

[Chris_Bryant]

Just keeps getting cheaper- UNO R3 ATMega 328 arduino *with* a 2.4" touch screen for $12.20.
Often thought about combining with a mega/mean/cheapo watt power supply, a digital potentiometer, and a few sensors- the arduino can directly measure voltages, but external would be more accurate, and still cheap, along with temperature sensors, for ambient, battery, and power supply. You could make a *real* smart charger.

I have heard that the modules are pretty easy to work with and a lot of fun. I just seem to have too many hobbies right now.

For those that want a system to call them via cell when the motorhome gets too hot for the pets, this seems the way!
