I am currently working my way through the examples but cant seem to find a particular way of sending data from a PC to the Adrunio which will switch on 8 digital outputs.
I would like to be able to send instruction as a Byte from the PC with some sort of identification attached which would be stripped from the data before being transmitted.
Ideally I want the unit to serve my project using multiple comm send and receives for data aquisition.
Also i keep reading that i cant use pins 4 & 5 as they are dedicated to Serial Comms.
Im using the Mega is this still true
incidently the pin map starts at pin 1 not 0 WHY!
the functions dont even coincide as pin 1 is a PWM pin?
and no not the famous Microsoft suggestion
I discovered another member asked a similar question about pin mapping, when your confronted with a new piece of technology it hard to get your head around what the manufacturers are trying to convey if they dont actually make a statement anywhere which spells it out.
