I have two arduinos operating in tandem. each with its own photocell and a buzzer to enunciate when a laser beam is broken. I can't get them to communicate. I just need the first device (call it "A") to tell the second device ("B") when its sensor is tripped. B then keeps track of when either device…

How to easily send data from one arduino to another?

Bilroy: Ohhhhhhh...yeah, that um...makes some sense. I'll try that first.

Nick, I'll try your suggestion next and get back to both of you asap.
