 Bigger Bigger  Smaller Smaller  Reset Reset

Hello there,

I have a question:

The situation is as follows.

Arduino 1: MEGA > XBEE + Keypad, LCD screen, Joystick, some buttons, Faders.

Arduino 2: UNO r3 > XBEE connection with Arduino 1. And wired connection with Arduino 3: Arduino used voor movement of robot plaform.

Arduino 3: UNO r3 > Wired connection with Arduino 2: Used vor Animatronic head...

Now the question: How do I connect all the Arduino's together.. witch the least used pins..

Grtz,
