Explain how the following Arduino codes affect the motion of the motor. Which direction is the motor moving? Why the map commands are required? (6%) duty1 = 40; duty2 = 60; dutyl-map (dutyl,0,100,0,255); duty2-map (duty2,0,100,0,255); analogWrite (pinIN1, dutyl); analogWrite (pinIN2, duty2); How shall you revise the above Arduino code to approximately double the speed of motor? Reverse the rotation direction? And then stop the motion of the motor? (6%)
