Error code

Welcome all:

What this error means?
What's the solution?

:disappointed_relieved: :disappointed_relieved:

Copy the error from the IDE and post it here in code tags along with the complete program.

avrdude: verification error, first mismatch at byte 0x0000
0x0c != 0x00
avrdude: verification error; content mismatch

That error message indicates that one or more of many things could be wrong. When you post the error message here by pasting with code tags, then someone will be able to help you. I doubt that posting the program will help, but telling us about your IDE and version, PC, OS, and Arduino may help.

The IDE could not program your Arduino. The cable or Arduino is missing or disconnected, perhaps there is a problem with your PC or your installation, or perhaps your Arduino does not have power, or perhaps you have a bad processor, or it could be any of the other things that can keep you from programming your Arduino.

Or you have not specified the correct serial port.

Yes, although choosing the wrong serial port and most of the things that I listed would have failed earlier with an error message about "wrong identifier".

Hello!

Here is my code i'm experiencing error messages when uploading my codes at the bottom please assist

#define trigPin 12
#define echoPin 13
int Buzzer = 8;

void setup() {
// Serial.begin (9600);
pinMode(trigPin, OUTPUT);
pinMode(echoPin, INPUT);
pinMode(Buzzer, OUTPUT);
}

void loop() {
//
int duration, distance;
digitalWrite(trigPin, HIGH);
delayMicroseconds(1000);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH);
distance = (duration/2) / 29.1;
if (distance >= 80 || distance <= 0){
Serial.println("no object detected");
digitalWrite(Buzzer, LOW);
}
else {

Serial.println("object detected");
tone(Buzzer, 400); // play 400 Hz tone for 500 ms
delay(500);
tone(Buzzer, 800); // play 800Hz tone for 500ms
delay(500);
tone(Buzzer, 400); // play 400 Hz tone for 500 ms
delay(500);
tone(Buzzer, 800); // play 800Hz tone for 500ms
delay(500);
tone(Buzzer, 400); // play 400 Hz tone for 500 ms
delay(500);
tone(Buzzer, 800); // play 800Hz tone for 500ms
delay(500);
noTone(Buzzer);
}
delay(300);
}
