hello Mickael

I would like to know if it is very there that I have to modify the 10 seconds by default of the countdown.

The part in red

And I would like to know the tension of functioning of the buzzer? it’s 2v ?

The time is good in milliseconds?? 1 secondes = 1000 ??

thank you..
**********************************************************************************

// Reset back to the last second boundary so we can start the countdown
// immediately and so that the first second isn’t truncated
TCNT1 = TIMER1_SECOND_START;

beep(3800, 30);
digitalWrite(LED_DET, ledCurrentState);
while ((countdownSeconds > 0) && (!defused)) {
for(int i=0;i<10000;i++) { //10000 represent 10 seconds?
// get input
if (digitalRead(defusePin) == HIGH) {
defused = true;
break;
}
if (digitalRead(detPin) == HIGH) {
countdownSeconds = 0;
break;
}
}
delay(20);
if (ledCounter++ > ledCounterThreshold) {
ledCounter = 0;
if (ledCurrentState == HIGH) {
ledCurrentState = LOW;
} else {
ledCurrentState = HIGH;
}
digitalWrite(LED_DET, ledCurrentState);
}
}
digitalWrite(LED_DET, LOW);
countdownRunning = false;
if (!defused) {
detonate();
} else {
beep(4500, 80);
delay(2000);
displayCountdown = false;
}

Laurent,

The default countdown of 10 seconds is defined here:

#define COUNTDOWN_DURATION 10

You can change that.

The buzzer is driven by a 5V PWM square wave.

thank you …mickael…

I finished my 1st version of my “bomb”

I would make another “bomb” soon, even more beautiful..

Merry christmas and good year Mickael

Merry Christmas and Happy New Year, Laurent. Your project looks wonderful! Great job.

yep, we started calling it the burrito because as we were building it, everyone kept calling it the “bomb” and I didn’t want any extra “attention” called to us (as i am sure you have experienced). I dont have it with me right now, but hopefully later on this week or next I can get a good picture for you.

Thanks again for making this open source!
