noob help with buttons.

Projects General Guidance

I literally just started yesterday on learning the arduino language but i know a good amount of css and javascript so i understand how the format works and i kinda get how to do things on the arduino. the one thing I'm trying to do is set an input command on a button that starts a void loop when pressed. kind of like an ignition button on some cars. what i have setup is:

int button = 5;
int led = 9;

void setup(){
pinMode(button, INPUT);
pinMode(led, OUTPUT
}

void loop(){
digitalWrite(led, HIGH);
delay(0500);
digitalWrite(led, LOW);
delay(0500);
}

what i need to figure out is how to start void loop with int button command which i have had no luck tinkering with the lines. any help will be most appreciated!

i also added
int button2 = 7;
pinMode(button2, OUTPUT)

digitalWrite(button2, HIGH);

so the button has an input and output but i still dont know how to get it to engage the loop and whatnot.

You need another loop. I'd probably use a while() loop. Run a "do nothing" while loop and break-out of the loop and continue when the button is pushed.

the loop is always running
however you can go to a function
put this in loop
IF (button=HIGH){dosomething()}
below loop
void dosomething()
{digitalWrite(led,high)
}

kind of what i want but i dont want void loop to stop. i want it to start but not stop until i hit reset. kind of a governing command.

shooter:

put this in loop
IF (button=HIGH){dosomething()}
below loop
void dosomething()
{digitalWrite(led,high)
}

ill give this a try.

ok so that didnt work. it just automatically blinks as soon as i upload the code.

this is the code i set

int button = 5;
int led = 9;
int button2 = 7;

void setup() {

pinMode(button, INPUT);
pinMode(button2, OUTPUT);
pinMode(led, OUTPUT);
digitalWrite(button2, HIGH);
}
void loop(){
if (button=HIGH){dosomething();}
}

void dosomething(){

digitalWrite(led, HIGH);
delay(0500);
digitalWrite(led, LOW);
delay(0500);

}
