Yea thats me. Its actually a full water cooling information center. It will read the RPM of 2 fans, 2 pumps, display temperature from 4 locations, display liquid flow rate in lph, and sound an alarm if the flow stops.
Arduino is a fun way to learn c++ well a derivative of it anyway. But I have a AVR devboard that just uses c++ and AVRdude to compile and upload. Of course this is all for physical computing and I know nothing about building software apps or things like that.
