Interfacing of ADC with Microcontroller

In this article you will learn how to interface ADC with 8051 microcontroller. The ADC is not inbuilt in 8051 microcontroller. If The main purpose of DC interfacing with 8051 microcontroller is for controlling the speed of the we want to sense analog value for processing, we can not interface directly to the controller. We need an Analog to Digital converter (ADC). For example, you want to measure temperature. You need to interface any temperature sensor LM35 with microcontroller. The output of LM35 is analog. So we need to use ADC to convert analog value to digital.
