L298 MOTOR DRIVER- Driving a DC Motor- Selecting suitable STEPPER to avoid over Heating

L298 is dual H Bridge Motor driver module capable of sourcing 2 Amps Current.
This video first demonstrates how to control a DC Motor & vary its speed using PWM.
Then BIPOLAR / UNIPOLAR Steppers are tested.
IMPEDANCE of Stepper coil plays very important Role in Heating up the Driver module.The lesser the impedance the greater the Current consumption , resulting in heating up of L298
