ok I got a button push counter integrated into the sketch. It now triggers pin 13 (an LED / event) when the button is pushed 4 times (very slowly :~ got to figure that out also ). I also think i've got 'most' of an integer variable setup right for each of the sensors but I think I'm missing a little bit.
Basically I need the LED / event to trigger switching to the next menu item and when it comes to the end, it goes to the beginning. Tie the event (LED high) to switch to one of the sensorVar (I think)
Here's my code as it sits now. Of course I'm open to all suggestions.
#include <LiquidCrystal.h> // include the LCD library
#include <LcdBarGraph.h> // include the LCDBarGraph library

byte lcdNumCols = 16; // -- number of columns in the LCD
LcdBarGraph lbg(&lcd, lcdNumCols); // -- creating
// SENSOR VARS (Telling the Arduino ports which to activate, ran once on startup)
const int buttonPin = 5; // the pin that the wheel switch is attached to
const int ledPin = 13; // the pin that the LED is attached to
int buttonPushCounter = 0; // counter for the number of button presses
int buttonState = 0; // current state of the button
int lastButtonState = 0; // previous state of the button
int sensorPin0 = 0; // -- value for this example
int sensorPin1 = 1; // -- value for this example
int sensorPin2 = 2; // -- value for this example
int val = 0; // variable for reading the pin 0 status
// float maxVoltage = 4.65; // Maximum voltage sent out from the sensors (these values are the same for O&F not for B)(For a later time)
// float minVoltage = .46; // Minimum voltage sent out from the sensors (these values are the same for O&F not for B)(For a later time)
// float scale = 4.5/1024.0; // convert 10-bit value to 4.5v scale for sensor (will need this for scaleing the sensor)(For a later time)
