@ kishan1234_arduino Why did you delete some functions from the code linked to from the YouTube video ?

There is no readPing() function in the latest code you posted

please tell me what change i should do in my code [code] #include #include #include #define TRIG_PIN A4 #define ECHO_PIN A5 #define MAX_DISTANCE 200 #define MAX_SPEED 190 // sets speed of DC motors #define MAX_SPEED_OFFSET 20 AF_DCMotor motor1(1, MOTOR12_1KHZ); AF_DCMotor motor2(3, MOTOR12_1KHZ); long distance ; Servo myservo; void setup() { myservo.attach(9); myservo.write(115); delay(2000); distance = readPing(); delay(100); distance = readPing(); delay(100); distance = readPing(); delay(100); distance = readPing(); delay(100); // put your setup code here, to run once: } void loop() { int distanceR = 0; int distanceL = 0; delay(40); if (distance = distanceL) { turnRight(); moveStop(); } else { turnLeft(); moveStop(); } } else { moveForward(); } distance = readPing(); }// put your main code here, to run repeatedly: } [/code]

Hi, [image] kishan1234_arduino: readPing was not declared in this scope You need to look at the NewPing examples in the IDE. Select "file", then "Examples", then "NewPing", there are some basic examples there for you to look and try. Is this a school/college/university project/assignment? Tom... :grinning: :+1: :coffee: :australia:

Greetings, #include #define TRIGGER_PIN 12 #define ECHO_PIN 11 #define MAX_DISTANCE 200 NewPing sonar(TRIGGER_PIN, ECHO_PIN, MAX_DISTANCE); void setup() { Serial.begin(115200); } void loop() { delay(50); Serial.print("Ping: "); Serial.print(sonar.ping_cm()); Serial.println("cm"); } Maybe this example will help you understanding the newPing library.

please tell me what change i have to do in my code

@ Burakimportant Thanks for updating your post using code tags Do you see how much better it is ?

Thanks for the advice, It is more readable now.

Please corect this code
