Hey guys.
I have a homework assignment where i need to make a
stoplight function that has 2 different stages, depending on day or night.
I have set a couple of variables with time in milliseconds.
The strange thing i am running into is that all time variables work correctly accept 1.
I have the timer set to 90000 milliseconds and the monitor returns 24464.
If i change the time to something lower then 31000, i get the correct results in the monitor.
If i take out the variable and simply place the time (90k) into the delay directly, it seems to work.
Right now i have no clue to what causes this issue to arise.
Could anyone explain to me why i am unable to declare a time above 31k into a variable ?
Many thanks.
PS. this is the code i have so far.
It is not finished nor cleaned up.
// Stoplight assignment

const int greenLightTimerCars = 90000;
const int redLightTimerCars = 20000;
const int orangeLightBlinker = 350;
const int switchDelay = 3000;
int active = 0;

Serial.begin(9600);

pinMode(i, OUTPUT);

}
}
void loop() {
sensorstate = analogRead(sensor);
