Help- which Arduino to get!

G'day All,

I am currently looking at using a arduino for a project that I am doing at uni.
what i have is 10 ( though maybe 20 if things go well) analoge signals which will use to open and close 10 (or 20) ball valves using servos or motors. Each valve will have open slightly or close slightly according the the voltage level of the input(ie input voltage=5v, valve fully open, 2.5v half open, 0v closed, etc).

I was thinking of using an Arduino for the control of the servos and use a bunch of if statements to output to the servos.

Does anyone have any thought on what would be the best arduino to use??

Cheers

Probably the one with the most I/O ports considering what you have stated. If you plan to attach various shields then you need to consider which ones the will/won't fit.

I guess you should go with the Arduino Mega, yet even that one only has 16 analog pins 0-15.
