I connect 3 ultrasonic sensors, but the last one is working properly. There is no problem with the circuit, I tried everything. here are the codes #define trigPin1 2 #define echoPin1 3 #define trigPin2 4 #define echoPin2 5 #define buzzer 9 #define potentiometer A0 int valueOfPot; int freque…

delay is negligible. I just put a delay between 3 sensors. like this firstsensor(); delay(200); secondsensor(); delay(200); thirdsensor(); delay(200); thank you all for your help

3 ultrasonic sensors, only 1 works properly

Just put a short delay between your two readings.
