In this mode, a constant current is applied to both coils *A* and *B*. The motor is stepped by alternatively flipping the direction of the current flow in each coil as follows:

Note that though the pattern repeats after four steps, it is not symmetrical - running the pattern from left to right causes the motor to rotate in one direction, whereas running the pattern from right to left will cause it to rotate in the opposite direction. Many stepper motors are constructed to have 200 full steps, which means you need to repeat the above pattern 25 times to cause the motor to complete a single revolution.

### FULL STEP ONE PHASE
In this mode, each coil can be in one of three state -
In this mode, a constant current is applied to only one coil, either *A* or *B*, at the same time. The motor is stepped by alternatively applying the current to each coil, while also flipping its direction as follows:
