**Analog to digital converter.**
This project is about a simple analog to digital converter based on the ADC0804 IC. ADC0804 is an 8-bit ADC with adjustable step size. It is very easy ti interface it to microcontrollers. In face am ADC circuit like this one is very essential for designing systems based on microcontrollers like 8051 which does not have a built in ADC.
