Hi, I am working on a sketch that has two if loops. See code below:#define led_bottom 19 //led pin
int long unsigned time_1; //initial time
int long unsigned time_2; //final time
int long unsigned Time; //Delta Time
void setup () {
Serial.begin(9600);
pinMode(led_bottom, INPUT); //Set bottom led pin as input
digitalWrite(led_bottom, HIGH);
}
void loop() {
if (digitalRead(led_bottom)==HIGH) { //Checks if bottom led is high
time_1=micros(); //If high, takes time measurement
delay(30); //delay for bouncing
}
if(digitalRead(led_bottom)==LOW) { //Checks if bottom led is LOW
time_2=micros(); //If low, takes time measurement
delay(30); //delay for bouncing
}
Time=time_2-time_1;
Serial.print("T1= "); //Text to monitor
Serial.println(time_1); //prints time 1
Serial.print("T2= ");
Serial.println(time_2); //Prints time 2
Serial.print("Delta T= ");
Serial.println(Time); //Prints final-initial timme
}
My question is, how can i get the first if statement to wait until the condition is true before it moves on, I need the second if statement to do the same.
You can put a line with return after the delays.
