When I first dived into the world of analog-to-digital conversion, I decided to start with a classic project using the National Semiconductor ADC0804. This 8-bit ADC, which works seamlessly with 8-bit microprocessors and microcontrollers, quickly became my go-to for understanding how analog signals are digitized.

In this setup, I used a CDS photocell as my analog sensor, which measures light levels. The ADC0804 converts this light-based input into an 8-bit digital value, ranging from 0 to 255.

I then sent this digital data through 8 lines to a USBMicro interfacing device plugged into my laptop, making it easy to see the conversion process in action.
