Handshaking with 2 Dobots


Looking for a simple way to handshake b/w two Dobot Magicians utilizing the back of the base. Each robot should be able to send and receive inputs and outputs to communicate.

I have successfully used a 4n35 chip to send and receive an input and an output in one direction, but was unable to go back and forth.

Hoping a simple wired connection from one robot to the other will suffice. Fingers crossed.

Thank you in advance.



I uses this manual fron the chris and jim robots site.
