The circuit of the voltage meter is mainly consisted of three mould pieces: A/D converting mould piece, A/D converting is mainly pleted by the ADC0832, it converts the collected analog data into the digital data and transmits the oute to the manifestation controlling mould piece. Data processing is mainly pleted by the AT89C51 chip, it processes the data produced by the ADC0832 chip and generates the right manifestation codes, also transmits the codes to the manifestation controlling mould piece. Also, the AT89C51 chip controls the ADC0832 chip to work. The voltmeter features in simple electrical circuit, lower use of elements, low cost, moreover, its measuring precision and reliability. The voltmeter is capable of measuring voltage inputs from 1 route ranging from 0 to 5 volt, and displaying the measurements though a digital code tube of 7 pieces of LED.
