Hi i am working on a project and i have a really big problem in coding
I am working with 10 arduinos using 8 channels on each working
i need a way to send different codes to them all at once
For example send "mp" to board1 and "mn" to board 2 at the same second without any delay between them
am using xbee s1 as a radio module
What you are asking is impossible codes must be sent one at a time. The good news is that they will be fast for a human and they will not seem like they are one at a time. The same second is a long time.
Can you describe your setup more precisely? Does each arduino have it's own Xbee?
