I2C Scanner - Arduino Playground - No message

I am new to Arduino Microcontroller, and I need to use Arduino Mega in my new work.
I was trying to check what is the address for each driver and vibration motor, connected via I2C communication.
I upload the code I2C_scanner from Arduino Playground → Arduino Playground - I2cScanner

However, in my serial monitor does not appear the expected messages…See image in attachement.

Is the code or the connections are not well made? :confused:

Thanks!
