Hey there, I would like some help fixing this code. It gives the error in the void setup()

  ZumoMotors.flipRightMotor(true);

This line uses an object named ZumoMotors but you have not declared that object

Are there any examples with the Zumo libraries ?

[darren.leong24]

The code i posted was one of the examples but i changed it and uncommented

motors.fliprightMotor(true)

but that didnt work so I changed it to

 ZumoMotors.flipRightMotor(true);

and that had the issue above
