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? 
Thanks!
