Hi guys.
This is my first project and it's ambitious for a first!
Erm. In a nutshell - I've modded some existing projects and Arduino code out there to create an ambient led lighting system that outputs colours that appear on screen.
This is computer-only as it's using Java to average the colours in 4 seperate areas (bottom left, top left, top right, bottom right). The PC Java code passes the averaged RGB values to the USB and the Arduino (master) would send the first half of the values to the other Arduino (slave). This is due to the Nano's are only have 6 digital PWM pins.
The reason I chose Nano's (rather than a Mega) was because I wanted to keep this project small (physically).
Here's my current setup thus far *see attached or below if it works:
As you can see, I've got 2 Arduino Nanos (3.0) and only 1 attached to the PC. This is what I would like to maintain but am struggling to communicate between the two Arduinos.
*Note: The diagram doesn't link the 2 Arduinos as I wanted to ask you guys for the correct way.
I've tried NewSoftSerial but I'm not sure I'm really doing it correctly, as I said - this is my first Arduino project.
If the brains of this forum could assist me in telling me how to go about communicating between the 2 Arduinos I would be forever grateful and would like to setup a 'how-to-guide' after completion.
I can provide my code if it helps but I just thought I'd show you what I'm trying to achieve and then we can perhaps talk basic serial communications first!
