Hi, I'm currently building a arduino based robot platform.
I would like too use two microcontrollers together
- A Mega 2650 R3 the serious stuff (Motor driving, Sensor Inputs, Xbee, GPS)
- A 5V pro mini 328 for auxillarys (Lights, Sounds, etc)
Its too complicated in software to do all that on just my Mega. I would like to power them off the same source and also have serial communication between the two for simple commands.
Will The two microcontrollers communicate if i just hook straight UART serial between them, or do i have to have something in between?
Thanks in Advance, Alex :)
