+## Inductors and motor driving
+
+-----
+
+### Inductors
+  - ####Inductors are devices that store energy in a magnetic field.  V= L*di/dt

+  ![picture of inductor circuit RL](../images/inductor_circuit.jpg)
+
+  Figure:  1.  Symbol and examples of inductors.  2.  Inductor circuit.
+
+  - ####driving inductive loads - flyback diodes.

+
+### Motor driver
+
+- ####To drive a motor, you need to be able to switch current direction.  The usual solution is the h-bridge geometry.
+

+- ####Here is a module, and the chip that we will use to drive up to 3.5A of motor current.
