+# Pivot Turn
+
+A **pivot turn** happens when a [EV3 Driving Base](https://le-www-live-s.legocdn.com/sc/media/lessons/mindstorms-ev3/building-instructions/ev3-rem-driving-base-79bebfc16bd491186ea9c9069842155e.pdf) turns around a wheel by spinning a single wheel.
+
+You can achieve turn with a ``tank`` or a ``steer`` block.

+```blocks

+    motors.largeBC.tank(50, 0, 2, MoveUnit.Rotations)
