# Turn With Gyro
## Introduction @fullscreen
Use the gyro to measure how much the robot is turning, regardless if your wheels are slipping.
## Step 1 Calibrate
Add the ``||sensors:calibrate gyro||`` block to make sure your gyro is ready to use.
```blocks
sensors.gyro2.calibrate()
```
## Step 2 Turn
Use motor blocks to make the robot turn. Don't go too fast!
```blocks
sensors.gyro2.calibrate()
motors.largeBC.steer(200, 20)
```
## Step 3 Pause for turn
Use the ``||sensors:pause until rotated||`` block to wait until the desired amount of rotation has occured.
```blocks
sensors.gyro2.calibrate()
motors.largeBC.steer(200, 20)
sensors.gyro2.pauseUntilRotated(90)
```
## Step 4 Stop
Stop the motors!
```blocks
sensors.gyro2.calibrate()
motors.largeBC.steer(200, 20)
sensors.gyro2.pauseUntilRotated(90)
motors.stopAll()
```
