What have i done wrong?

int switchstate = 0;

void setup() {
pinMode(3,OUTPUT);
pinMode(4,OUTPUT);
pinMode(5,OUTPUT);

pinMode(2,INPUT);

}

void loop() {

switchstate = digitalRead(2);

if(switchstate == LOW)
digitalWrite(3,HIGH);
digitalWrite(4,LOW);
digitalWrite(5,LOW);
}

else {
digitalWrite(3,LOW);
digitalWrite(4,LOW);
digitalWrite(5,HIGH);

delay(250);
digitalWrite(4,HIGH);
digitalWrite(LOW);

delay(250)
}
}

 if(switchstate == LOW)

You missed a { after that.

You also missed the code tags

thanks ; :slight_smile: code tag?

[code][/code]

You can have those - they're a spare pair I had lying around

okkk, hmm, it still doesn't accept my written version, even though now it is identical to the example version ?

Nope, didn't understand that at all.
Please feel free to post your revised code.

int switchstate = 0;

void setup() {

pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);

pinMode(2, INPUT);
}

void loop() {

switchstate = digitalRead(2);

if(switchstate == LOW){
digitalWrite(3, HIGH);
digitalWrite(4, LOW);
digitalWrite(5, LOW);
}

else {
digitalWrite(3, LOW);
digitalWrite(4, LOW);
digitalWrite(5, HIGH);

delay(250);
digitalWrite(4, HIGH);
digitalWrite(5, LOW);

delay(250);
}
}

Again, the code tags are noticeable by their absence, but otherwise things look OK to me.

sorry yeh, its working now, thanks
