I have two Arduino Uno boards. I also have this wireless shield attached to each Arduino board:
I have a proximity sensor connected to Arduino #1 as well as an LED to turn it on and off. I want to also control the LED on Arduino #2 via the proximity sensor attached to Arduino # 1.
Apparently it is plug and play, and I seemed to have it working, but there is a delay between the switch on Arduino #1 and the LED on Arduino #2.
I have attached the sketch files, but need help to make them work so there is no delay.
I have also attached a picture of the current set-up, there is still a delay here. If I remove the hardwired connection and replace with the wireless shields that are plug and play, it works the same, still a delay.
Really need this done within the next couple of days.
