Need Help With RandomSeed and Number Count

[jlfalin]

Hi,  I am new to Arduino.  I am currently trying to make a controller to control a variable speed fish aquarium pump.  During playing with the coding I ran into a small problem.  I am trying to have a randomseed generator run to produce random numbers.  I am also trying to run a push button counter that will allow me to switch between the different modes that I want to run.  Can these two things be done at the same time on an Uno.  Here is my code.  The pushbuttoncounter was working great until I added the  randomSeed(analogRead(1)); statement now nothing works and I cannot select between my different options.  Any input would be greatly appreciated.

Code: [Select]

const int LED = 13;
const int BUTTON = 7;
const int TxPin = 6;
long RandomIN;
long RandomOut;

#include <SoftwareSerial.h>
SoftwareSerial mySerial = SoftwareSerial (255, TxPin);


int buttonPushCounter = 0;
int buttonState = 0;
int lastButtonState = 0;

void setup(){
  pinMode(LED, OUTPUT);
  pinMode(BUTTON, INPUT);
  pinMode(TxPin, OUTPUT);
  randomSeed(analogRead(1));
  Serial.begin(9600);
}

void loop(){
    buttonState = digitalRead(BUTTON);
  if (buttonState != lastButtonState) {
    if (buttonState == HIGH){
      buttonPushCounter++;
      Serial.println("on");
      Serial.print("number of button pushes: ");
      Serial.println(buttonPushCounter);
    }
    else {
      Serial.println("off");
    }
  }
   
    lastButtonState = buttonState;
   
if (buttonPushCounter == 0) {     
    mySerial.begin(9600);
    delay(100);
    mySerial.write(12);
    mySerial.write(17);
    delay(5);
    mySerial.print("Ramp Mode");
    mySerial.write(13);
}

if (buttonPushCounter == 1) {
   mySerial.begin(9600);
    delay(100);
    mySerial.write(12);
    mySerial.write(17);
    delay(5);
    mySerial.print("Wave Mode");
    mySerial.write(13);
   }

if (buttonPushCounter ==2) {
  mySerial.begin(9600);
  delay(100);
  mySerial.write(12);
  mySerial.write(17);
  mySerial.print("Reef Crest");
  mySerial.write(13);
  }
if (buttonPushCounter ==3){
  buttonPushCounter =0;}
}
