I'm about to start my first project with Arduino board, but before beginning I'd like to know if it's feasible and how much knowledge it requires.
I need to read from a VB.net software through Ethernet connection three temperatures from sensors located several meters from the board, as well as driving four low current relais.
I'd like to know:
- can i do it with one board?
- from a sketch programming point of view is it much complicated to transmit via Ethernet than USB?
- which sensor do you suggest? I read about LM35 and AD595. Remember the thermocouple must be placed severa meters from the board, need 0.1°C precision and the least complicated circuit - after all it's a DIY project
Thank you for the help!
