How to run the ultrasonic sensor while the button Blynk V2 is pressed?

Problem with ultrasonic

better use basic function instead of Newping I already used Newping to test it, but I prefere to use that digitalWrite(TRIGGER, LOW); delayMicroseconds(2); digitalWrite(TRIGGER, HIGH); delayMicroseconds(10); digitalWrite(TRIGGER, LOW); duration = pulseIn(ECHO, HIGH); distance = ((duration / 2) / 29.1) * 10;
