I am having some trouble trying to figure out how to increment a timer to be referenced in if and while statements in a second loop. I want to be able to get rid of the timer incrementation in the while statements so I can just have one timer to reference by. I would like to have the timer count down from a set value then keep counting down in 1 second increments until 0 while the buzzers go off. If I could have something like a completely separate loop for the timer increment counter and a completely separate one for the buzzers and whatever else I want to add later such as a timer display or something.
#include <Tone.h>
Tone tone1;
Tone tone2;
long countervalue = 1;
int RLED = 1;
int YLED = 2;
int GLED = 3;
int button = 0;
void setup(){
tone1.begin(4);
tone2.begin(4);
pinMode(RLED,OUTPUT);
pinMode(YLED, OUTPUT);
pinMode(GLED, OUTPUT);
pinMode(button,INPUT);
}
void loop()
{
while(countervalue < 4){
digitalWrite(GLED,HIGH);
tone1.play(575 , 150);
delay(3000);
countervalue = (countervalue+1)%1000000;
digitalWrite(GLED,LOW);
}
while(countervalue <= 8){
digitalWrite(YLED,HIGH);
tone1.play(100 , 1000);
tone2.play(250 , 1000);
delay(2000);
countervalue = (countervalue+1)%1000000;
digitalWrite(YLED,LOW);
}
if(countervalue == 9){
digitalWrite(RLED,HIGH);
tone1.play(350, 1000);
delay(1000);
tone1.play(200, 1000);
delay(1000);
countervalue = (countervalue+1)%1000000;
}
}
