Hello guys and girls,
I'm completely new to arduino, but i'm feeling very excited!
i searched a lot for a simple switch code... and didn't find any that I liked... so I tried and tried and made out this:
const int buttonPin = 8;
const int ledPin = 13;
int buttonState = 0;
int antState = 0;
void setup()
{
pinMode(ledPin, OUTPUT);
pinMode(buttonPin, INPUT);
}
void loop()
{
while(buttonState == 0)
{
buttonState = digitalRead(buttonPin);
}
antState = 1 - antState;
digitalWrite(ledPin,antState);
delay(200);
buttonState = digitalRead(buttonPin);
}
Isn't big deal but made me very happy!! I just wanted to share... =)
thanks a lot!!!
true... i can put some code inside the while....
but if i put too much code it will get lazy to respond the button click...
anyway... I was just trying to do a simple switch for some basic function... It seems to be working properly... when I start to build bigger things I'll need to search something more stronger...

I have not checked, but the execution time for each command is well below 1µS.
That would take quite some code before you will even notice a dealy from a mechanical button.
I'd say you could have all your code in that while loop, and still not get any noticeable delay.
Arduino is a microprocessor, not an early type motordriven mechanical calculator

First you should check,
second there are no commands in C/C++ function call yes, statements yes, but no commands.

Stupid - you don't put more code in the while loop YOU GET RID OF THE WHILE LOOP.

You are a nuisance Mark.
First I found a screaming post from you elsewhere shouting out in fat capital letters, and now here this insulting language.
Try being a bit more civil and gain some respect.
I think he didn't noticed the "Newbie" status... =P
So far in all your posts you have yet to get anything right. Go away, learn , at leat a little. But most of all keep your "help" to your self.
