Questions - Options to connect to another IC

I am having a questions on connecting arduino to other IC, appreciate any comments or advice.

Is it possible to connect Arduino to MSP430 chips, via I2C?

The plan is to have 3 to 4 MSP430 chips, each controlling 4-6 LEDs, and each of these MSP430 receives commands from a single Arduino. Is it possible or are there better options out there?

The arduino I have is a MEGA, so it should have enough pins for the whole thing. However I'd like to learn and take the opportunity to practice I2C communication. Any working samples or code or tutorial will be much appreciated.

Thanks in advance.

Thank you for your quick reply!

Yes it seems like an overkill. However i'd like to offload some processing to the 430, e.g. the arduino only need to send a command like 'turn the wigwag on' and then the 430 will take care of flashing a pair of leds continously.

But most importantly i wanted to learn and make this a practice :wink:

Do i have to worry about voltage?

Do i have to worry about voltage?

Always worry about the voltage, it's one of the rules. What voltage are you running everything at.
If it is all the same then the worrying period is over if they are not then worry some more.
