Thanks Mike, I was 90% there.
Sorted it now and cleaned the code up (thanks crossroads) so here is the code, I have specified three different patterns using 16 Led's. This code cycles through them using a push button.
//Using a pushbutton to cycle through various LED patterns
//16 LED's are used with two shift registers, used Arduino SHIFTOUT as a start
const int buttonPin = 2; // the pin that the pushbutton is attached to
const int ledPin = 13; // the pin that the LED is attached to
// Pushbutton int's Variables will change:
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
//LED 595 shift int's
//Pin connected to ST_CP of 74HC595
int latchPin = 8;
//Pin connected to SH_CP of 74HC595
int clockPin = 12;
////Pin connected to DS of 74HC595
int dataPin = 11;
void setup() {
//Pushbutton Setup
// initialize the button pin as a input:
pinMode(buttonPin, INPUT);
// initialize the LED as an output:
pinMode(ledPin, OUTPUT);
// initialize serial communication:
Serial.begin(9600);
//LED 595 shift setup
pinMode(latchPin, OUTPUT);
pinMode(clockPin, OUTPUT);
pinMode(dataPin, OUTPUT);
//display(43690);
display(48982);
}
void loop() {
// read the pushbutton input pin:
buttonState = digitalRead(buttonPin);
// compare the buttonState to its previous state
if (buttonState != lastButtonState) {
// if the state has changed, increment the counter
if (buttonState == HIGH) {
// if the current state is HIGH then the button
// wend from off to on:
buttonPushCounter++;
Serial.println("on");
Serial.print("number of button pushes: ");
Serial.println(buttonPushCounter, DEC);
}
else {
// if the current state is LOW then the button
// wend from on to off:
Serial.println("off");
}
}
// save the current state as the last state,
//for next time through the loop
lastButtonState = buttonState;
//Pressing the button once lights pattern 1, twice pattern 2 etc etc
switch (buttonPushCounter) {
case 1:
display(43690);
break;
case 2:
display(48982);
break;
case 3:
display(58163);
default:
buttonPushCounter = 0; // Resets counter to 0 so we can cycle through 1, 2, 3 again
digitalWrite(ledPin, LOW);
display(58163);
}
}
void display(unsigned int numberToDisplay){
digitalWrite(latchPin, LOW);
shiftOut(dataPin, clockPin, MSBFIRST, numberToDisplay); //lower byte
shiftOut(dataPin, clockPin, MSBFIRST, numberToDisplay); // higher byte
digitalWrite(latchPin, HIGH);
}
