How can I design a programming code to control the Arduino w

How can I design a programming code to control the Arduino with components of a button and a LED processing as following:

After I press three times to turn the LED on and press three times to turn the LED off.

Thank you all yoiu guys.

Solution

int ledpin=13; //LED isconnected to digital pin 13

int switchPin=5; //switch connected to digital pin 2

int switcvalue; //avariable to keep track of when switch is pressed

int counter=0; //my counter variable

//int couterValue; //a possble value variable for my counter

void setup()

{

pinMode(ledPin, OUTPUT); //sets the ledPin to be an output

pinMode(switchPin, INPUT); //sets the switch pin to bean INPUT

digitalWrite(switchPin, HIGH); //sets the default(unpressed) state of switchPin to HIGH

}

void loop()

{

switchValue=digitalRead(switchPin); //check to see if the switch is pressed

if(switchValue==LOW) { //if the switch is pressed then

degitalWrite(ledpin,HIGH); //turn the LED on

delay(200); //wait for a second

digitalWrite(ledoin, LOW); //turn the LED off

delay(200);

counter++;

if(counter>3) {

digitalWritten(ledPin,LOW); //turn the LED offand keepitoff(why isn\'t this working)

}

}

else { //otherwise,

digitalWritte(ledpin, LOW); //turn the LED off

counter=0;

}

}

after youhave the counteron 3, this part runs over and over again,

if ((switchvalue==low)&&(counter<=3)) { //if the switch is press then

digitalwrite(ledpin, HIGH); //turn the led on

delay(200); //wait for a second

digitalwrite(ledpin, low); //turn theled off

delay(200); //wait for a second

counter++;

}

if(switchvalue==HIGH)

{

counter=0;

}
