Find an alternative circuit elements that we can use for the reversed rotational motor. (other than potentiometer, for controlling motor speed and rotation)
Homework Answers
Instead of going for DC motors, we can also use AC motors.
In the case of DC motors, there are many types. One of the types is a brushless motor where 'Hall effect' phenomenon is used.
Hence, alternative circuit elements can be as follows,
1. Varying voltage
2. Using the method of magnetism
3. Using transistor such that the base current which can vary the circuit output
4. Using the logic circuit
5. a modulator (which will modulate the signal)
