Interfacing two arduinos in the same robot
April 14, 2011
I'm wondering if I can make two arduinos interface with each other i.e. one for the servos and another one for sensor reading and receiving commands by RF (no need for tx-rx). Sorta like a master and slave thing. I would just want actually to make variables that both arduinos can read and write. Is it possible by hooking the tx rx pins together?
