Slowing down commands

[hazza_ob]

So I'm back with another problem, this time to do with an addition feature of a program which interfaces a wii nunchuck with the two servos in a 'pan and tilt' camera mount.

 

The code: 

void loop(){  nunchuk.update();if ( nunchuk.cButton == 1 ) {    // light the LED if 'c' button is pressed    mode = mode + 1;    digitalWrite(ledPin8, HIGH);  }  else {    digitalWrite(ledPin8, LOW);  }if (mode >= 3) {    mode = 0;  }}

so here what I'm trying to do is have 3 modes set on 0,1 and 2. The mode is changed by adding 1 to the variable 'mode' however to eliminate delay in the refresh of the nunchuck i've tried to keep a delay as short as possible. However when button c is 1 (pressed down), the mode will continuously keep changing as 1 is always being added to 'mode'. So my question is this: is there anyway to make the program to add just 1 when the button c is pressed almost like a memory cell but won't continually add 1 like it is doing now? i've tried "delay(<time>);" already and it doesn't work. as always an example is always helpful and if i haven't made sense please tell me haha.

Thanks -Harry

Couldn't you add a "nunchuk.cButton == 0" after you're done using it to get inside the if statement? Or make a boolean that is is flipped in accordance to nunchuk.cButton and put that as the condition for the if statement?

i have a plan: to initialise the mode change when button 'c' is released... updates to follow

the problem I'm having is that its repeating the command many times per second so button 'c' is being registered many times every second each time the loop recycles making the 'mode' variable increase way too fast. i need a way of slowing this down so it goes up by one. nunchuk.cButton automatically goes back to 0 once i let go - this isn't the problem
