Keyword:  hand-held laser scannerscontrol panelLEDsingle chip microcomputer;
Abstract: Based on the design principle of controlling the output voltage from the LED by the microcontroller programming language,the adjustment of the background brightness of the control panel of the hand-held laser scanner is achieved. The system has a good human-computer interaction function. The operator can use the output voltage control of the microcontroller to achieve the control of the brightness adjusting on the background light.
