A connector assembly includes a female connector and a mal connector. The female connector includes a first main body and a number of slots defined in the first main body, and each slot receives a conductive terminal therein. First and second row conductive terminals are arranged along an opposite direction. A number of cables are attached to the first main body and electrically connected to the conductive terminals. A male connector includes a second main body and a number of conductive pins extend through the second main body. Third row conductive pins are corresponding to the first row conductive terminals. Fourth row conductive pins are corresponding to the second row conductive terminals. The connector assembly can transmit signals normally whatever the male connector is plugged to the female connector.

A circuit for driving a light emitting diode (LED), the circuit includes a timer, first to third electronic switches, and a regulator. The timer provides a pulse signal to switch the first and second electronic switches. The first electronic switch provides a first level signal to one end of the LED. The second electronic switch switches the third electronic switch on and off. The third electronic switch provides a third level signal to another end of the LED. The regulator adjusts the pulse signal to be at a predetermined frequency to control the first, second, and the third level signals to alternate between a high voltage level and a low voltage level at the predetermined frequency. The LED is driven to be on and off at the predetermined frequency by the first and third level signals.
