Question from Someone who is Supposed to be Answering Questions
August 24, 2010
rik and I were talking about this a few days ago and it crossed my mind again today.
What are your thoughts on sending serial data from one pic (say picaxe or arduino) to another pic and if you should have a current-limiting resistor in series between them. In my case, both chips are running off of the same 5v regulated power supply.
