Summary of 8051 ADC0808 LCD DISPLAY VOLTMETER
The article describes an 8051 microcontroller-based voltmeter project using the ADC0808 analog-to-digital converter. The system samples up to eight analog inputs, converts them to 8-bit digital data via address lines, and displays voltage readings on an LCD screen. It includes details on clock frequency settings (10–1280 KHz), reference voltage connections, and control signals like OE and EOC. Source code and Proteus simulation files are provided for implementation.Parts used in the 8051 ADC0808 LCD Display Voltmeter:

ADC0808 analog / digital converter of the 8 analog inputs (IN0-IN7) and 8-bit digital output (OUT0-OUT7) are available. Entries will be transferred to the digital output of the converter which converted to 3-bit ADD, ADD B, and C address ADD is decided according to the tips. ADC0808 to run the ADC clock (Clock) at the end of about 10 KHz-1280 KHz frequency values of the hour mark, which should be applied. VREF (+) terminal of the maximum amplitude of the analog signal to be sampled Vref (-) to indicate the minimum value of the signal to be sampled is used for. Applications Vref (-) usually bağlanır.start soil, OE (Output Enable) and the EOC (End of Conversion) are end-end control of the ADC0808.
