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.

RTC interface and LCD display in DAS

RTC Interface with Microcontroller

RTC is an electronic device which plays an essential role in realtime embedded system design. It provides a precise time and date in various applications such as system clock, student attendance system and alarm etc, that keep track on current time and provides consistent result to the respective task.

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.
