Hi,
You might think that there’s a lot of these types of questions, but I couldn’t find any answer of mine. Basically, I want to use a HC-SR04 Ultrasonic sensor. I know that I should use a SimpleTimer instead of doing the ultrasonic stuff inside the loop function. Right now I have this:
void Ultra()
{
digitalWrite(UltraTrig, LOW);
delayMicroseconds(2);
digitalWrite(UltraTrig, HIGH);
delayMicroseconds(10);
digitalWrite(UltraTrig, LOW);
duration = pulseIn(UltraEcho, HIGH);
distance = (duration/2) / 29.1;
if (distance <= UltraDist) {
StatusLED.setColor("#23C48E");
DoorState = 1;
}
else {
StatusLED.setColor("#D3435C");
DoorState = 0;
}
}
void setup() {
timer.setInterval(1000L, Ultra);
}
void loop
{
Blynk.run();
timer.run();
}
//It’s not the whole code it’s just a part of it
Is it ok to use the delay (or delayMicroseconds) within the Ultra function or should I do a separate function that will trigger those things with SimpleTimer?
