Thanks.
So I upload my program (sketch), It is stored in the EEprom obviously. Then I can forget about it 
that is awesome.
I planned on doing some Real time stuff. Thus I was going to use the MsTimer. I saw something that made it look like it may not work unless there is AVR( what is that) arcitecture. I guess to simplyfy the queston. Is that going to work on a stock UNO unit with out anything else being done?
I will have use for PC <-> Uno communiations but that looks simple with the serial.print features

PS. this thing looks so cool thinking of other uses for it already. Hobbies include RC vehicles of all types....
Maybe somehow implement a good home security system
