How to add off and on my led & buttons

Projects Programming

const int pins[3] = {5,7,9}; //led

void setup(){
for (int i=0; i<3; i++){

pinMode(pins[i], OUTPUT);
}
pinMode(10, INPUT_PULLUP);// b1
pinMode(11, INPUT_PULLUP);// b2
pinMode(12, INPUT_PULLUP);// b3

}

void loop(){

for (int i=0; i<3; i++){

if(digitalRead(pins[i]) == HIGH){

}
if (digitalRead(10) == LOW){ //b1
m = 0;
}
if (digitalRead(11) == LOW){ //b2
m = 1;
}
if (digitalRead(12) == LOW){ //b3
m = 2;
}
switch (m){
case 0: {
digitalWrite(5, HIGH); // led
digitalWrite(7, LOW);
digitalWrite(9, LOW);
delay(1);
break;
}
case 1: {
digitalWrite(7, HIGH);
digitalWrite(5, LOW);
digitalWrite(9, LOW);
delay(1);
break;
}
case 2: {
digitalWrite(9, HIGH);
digitalWrite(7, LOW);
digitalWrite(5, LOW);
delay(1);
break;
}

 }

}

Can you go to your code in your editor, hit CTRL T and then copy paste the code in code tags?
This way it is pretty hard to read.

Also:
What is your code supposed to do?
What does it actually do?
What is the difference?

i want to turn off the led

4

And what trigger is supposed to turn off the LED?

5

led only

6

i have a arduino simulator do you want to check ?

7

If you do not answer the question I can only suggest to take the plug out. Your LED will turn off then.

okey

9

if(digitalRead(pins[i]) == HIGH){

}

The } should probably be at the end of the sketch...

Now the if does nothing.
