Abstract :
The design is based on Atmel51 microcontroller development platform and automatic control based on the principle of a digital voltage meter system. The system uses Atmel89C52 microcontroller as the control core, ADC0832 for the sampled data system, The use of a zener diode for over voltage protection, and through the realization of analog switch achieves the input range automatic conversion, character liquid crystal display shows the measured voltage.
