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.

DC motor driver and relay driver in DAS

The main purpose of DC interfacing with 8051 microcontroller is for controlling the speed of the motor. The DC motor is an electrical machine with a rotating part termed as a rotor which has to be controlled. For example, consider the DC motor whose speed or direction of rotation of DC motor can be controlled using programming techniques which can be achieved by interfacing with 8051 microcontroller.

In some electronic applications we need to switch or control high voltages or high currents. In these cases we may use electromagnetic or solid state relays.

Serial Communication in Data Acquisition System

What is Serial Communication?

Serial communication is a process of transmitting data bit by bit. In this blog, you will learn how to serially communicate a device with a PIC microcontroller. You will also study the use of a communication component- UART (Universal Asynchronous Receiver Transmitter) present within the microcontroller.
