Hello, I turn to you with the issue that I've created a "distance meter" where I use the Ultrasonic Sensor HC-SR04 with 4 LEDs. The 4 LEDs continuously light up based on distance, with more LEDs lighting up as the object gets closer. My problem is that when none or only some of the LEDs are lit beca…

Solution: duration = pulseIn(echo, HIGH); delay(100); //Need to put here delay and the flashing stops distance = duration / 54.0
