I'm analyzing the requirements for a controller system I intend to build around the Arduino platform (if feasible). Rough specs;
5 PWM out 6 Analogue in 8 Digital in XBee (to peripheral devices (remote control & display, AC relays etc)) Ethernet (to web server and file storage) SD Card 16x2 LCD display (no need for special characters)
Considering the amount of pins required by the components (I will try to "mux" as much as possible with 4094 and it's cousins), and the amount of code the components will generate with all the libraries, will the UNO be sufficient or do I need to go larger?
Thanks for any advice!
