ABSTRACT:
A flashing apparatus controlled by an audio signal on a motherboard and a method for the same is proposed. The flashing apparatus has at least one cold cathode fluorescent lamp (CCFL), a motherboard and a controller. The CCFL is connected to a high voltage cable and receives a high voltage power to emit light of at least one color. The motherboard executes a sound effect software to send a lighting pulse signal to the controller. The controller is electrically connected to the high voltage power for the CCFL. The controller receives the lighting pulse signal and converts it into the high voltage power to make the CCFL flash.
