This is the arduino sketch I am trying to use. Any thoughts/advice would be greatly appreciated.
_____________________________________________
// This code was written by Click that moment.
// To adapt the code to your case, just change this top section, with the #define lines.
// Includes the watchdog timer library
#include <avr/wdt.h>
// This sets how many channels will vixen be sending. Can be set to any number from 1 to 48 for Arduino Mega, and 1 to 18 for Arduino Uno.
#define CHANNEL_COUNT 8
// speed for the com port for talking with vixen. From 9600 to 115200. Use the same speed as set in Vixen.
#define VIXEN_COM_SPEED 57600
// Timeout waiting for serial input before going to random mode (in milliseconds).
#define TIME_OUT 1000
// If the relays turn On and Off opposite to Vixen sequence, change "#define MODE NOT_INVERTED" for "#define MODE INVERTED"
#define NOT_INVERTED 0
#define INVERTED 1
#define MODE NOT_INVERTED
// which pins control which channels
// You can change these assignment to use different pins, but be very careful to not repeat the same pin number for 2 channels.
// DO NOT use pings 0 and 1, as those are for the serial port to talk to the computer.
