Problem Servo and I2C

Hello ,

I try to implement a project in which I have a master and slave by I2C. When I add a servo motor to the project , the servo does not work when the Transmision start .

I hope that you can help me .

Thanks .

Do you power the servo motor with the Arduino 5V pin ? Or do you use flat ribbon cable for the i2c bus ? Either the power is not strong enough (use a seperate power supply) or there is noise from the motors causing trouble in the i2c bus.
