set Reversed

Change the direction of rotation for a motor.

motors.largeA.setInverted(true)

You use a positive value (some number greater than 0) to drive you motor in the default direction. If you're using a motor in a way that makes more sense for your program to use a negative speed setting for that direction, you can reverse the speed range.

Paramters

• reversed: a boolean value that is false if the motor will use a speed value between 0 and 100 to turn in the default direction. If true, the motor uses a speed value between 0 and -100 to turn in the default direction.

Example

Run the motor connected to port A for 2 seconds at a speed of 30. Stop and switch the direciton of rotation. Run the motor at a speed of -30. Watch and see if the motor turns in the same direction as before.

motors.largeA.run(30)
pause(2000)
motors.largeA.stop()
pause(2000)
motors.largeA.setInverted(true)
motors.largeA.run(-30)
pause(2000)
motors.largeA.stop()
