Choose the true H-bridge motor statements in the list below. O The L298N has a PWM input signal that can be used to control the motor direction. (false, it controls the speed of the motor. O You should always transition through the "Off" state when changing direction with the H-bridge. O The H-bridge provides a means of controlling a motors spin direction. O If all four H-bridge switches are open, the motors will spin. O The H-bridge uses four switches to control the current flow.
