My first switch statement

Good catch Billabot!

That fun difference between the double equal sign == (compare) and the single equal sign = (assign) never gets old, does it?

I'm a suspenders-and-belt guy myself so I usually use >=  just in case it advanced an extra buttonst count:

For the hard time pressing the button, it's because the delay(1000) calls halt execution for a full second while nothing else gets checked. See the "caveat" of the reference page: http://www.arduino.cc/en/Reference/delay

You'd have to change the code quite a bit to make it multitask to catch the button press (or maybe the button can be handled via an interrupt? I haven't tried that in Arduino yet). Here is the example Arduino.cc gives: http://arduino.cc/en/Tutorial/BlinkWithoutDelay

Hope that helps.

Well guys I tried both of you solutions and goot the same result.  And that is the same thing I had before.  It almost acts as if it doesn't even see that line of code.

I only see you changing buttonst in this line:

    buttonst=digitalRead(8);

With that it can only ever be HIGH or LOW, so it won't ever be 10 or more.

If you're trying to increment buttonst with each keypress then you'd have to change your code to detect a button press (debounced so you don't interpret a single press as mutiple presses), and then increment buttonst by just 1.

Also, this code:

if (buttonst==HIGH)

    {//open state count

    if (buttonst==10)buttonst==0;                    RIGHT HERE

you only enter the if... statement if buttonst is "HIGH", which is defined as a single value (probably just 1). Then right after that you check if it's 10. So it will never enter the "right here" statement because it will never be both of those separate values.

Perhaps instead of buttonst you meant to use a separate counting variable like buttonCount ?

OK Guys I got it to work.  YEA!!!!!  The switch statement is working right and the counting is working just fine.  I made 3 different states and they loop around just like I want it to.  Thanks for all the help.  Anyone want to guess what I did?  Here it is.  I cookie for the first one to figure it out.  Now my next question is.  Can I put a switch statement inside a switch statement?  As it is now it will print both outputs.  The final version of the program will print one output at a time while remembering where the other output is at.  Also when 1 output gets to 3 both outputs will reset to case 0.

int state=8;//set pin 8 as state

int mi=9;  //set pin 9 as mi

int lastState=LOW;  //

int lastbutton=LOW;

int countmi=0;

int countst=0;

int button=LOW;

int buttonst=LOW;

void setup()

{// open void setup

Serial.begin(9600);  //print to monitor

pinMode(state, INPUT);//set pin 8

pinMode(mi, INPUT);//set pin 9

state=digitalRead(8);  //read pin 8

button=digitalRead(9);  //read pin9

}//close void setup

void loop()

{//open void loop

if (buttonst==HIGH)  //when buttonst = high count countst

    {//open state count

    countst++; //count countst

    Serial.println(countst); //print countst

    //Serial.print("state =");                      

    }//closes state count

  //   Serial.print(buttonst); 

           {// open switch

            switch(countst) //start the switch

                   {//open case

                     case 0: //case 0 first subroutine

                     buttonst=0;

                     flasha();

                     break;

                     case 1:

                     buttonst=1;

                     flashb();

                     break;

                      case 2:

                     buttonst=2;

                     flashc();

                     break;

                     case 3:

                     buttonst=3;

                     countst=0;

                     delay (1000);

                     break;

                    }// close case

          }//close switch

//   lastState=buttonst;

    buttonst=digitalRead(8);  // reaad pin 8

    if (button==HIGH)//pin 9 count

        {// open mi count

        countmi++;

        Serial.println(countmi);

        }//close mi count

                {// open switch

            switch(countmi) //start the switch

                   {//open case

                     case 0: //case 0 first subroutine

                     button=0;

                     flasha();

                     break;

                     case 1:

                     button=1;

                     flashb();

                     break;

                      case 2:

                     button=2;

                     flashc();

                     break;

                     case 3:

                     button=3;

                     countst=0;

                     delay (1000);

                     break;

                    }// close case

          }//close switch

//   lastbutton=button;

    button=digitalRead(9);

}//close void loop

  //open flasha

    void flasha()

    {

    int flasha;

    Serial.println("Hellow world");

delay (500);

  }//close flasha

  void flashb()

  {// open flashb

    int flashb;

    delay(500);

    Serial.println("Not gonna happen");

  }//close flashb

  void flashc()

  {

    int flashc;

    delay(500);
