Abstract
Official abstract text for this publication.
An indicator light control circuit includes a basic input output system (BIOS) integrated circuit (IC), a microcontroller, a signal control unit, an electronic switch, and an indicator light. The microcontroller includes a general purpose input output (GPIO) pin. When different operating options of the indicator light are set into and by the BIOS IC, the BIOS IC controls the GPIO pin of the microcontroller to output command signals, such as a low voltage signal, a high voltage signal and pulse signals, then the signal control unit generates and outputs signals according to the command signals. Thus, the electronic switch is operated to turn on or turn off or to pulse when controlling the operation of the indicator light(s).
