+# 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()
+```
