摘要
基于AT89C51单片机设计的数字电压表,可测试0—5V的电压值。电路采用AD转换芯片ADC0809将模拟测试电压信号转换为数字信号,并送入单片机中处理后,结合Proteus仿真软件在四位LED数码管上显示被测的电压值。
The digital voltmeter is designed by AT89C51 single-chip,which can test the voltage of 0-5V.It is used AD converter chip ADC0809 to transform analog signal into digital signal.The digital signal is sent into the microcontroller to be processed and is displayed on four LED digital with the Proteus simulation software.
