Cloud Computing Services and Model


Public Cloud The public cloud is available to the general public for systems and services. Public clouds can be safer than they are because of being open. Private Cloud Private cloud enables access to organization's systems and services. It's safer because of its peculiar nature. Cloud Community Community Clouds provide systems and services for a number of organizations. Hybrid Could Hybrid cloud is a mixture of public and private clouds that performs a critical cloud of the cloud when performing non-critical activities in the public cloud. Service models Cloud computing is based on service models. These are divided into three basic [...]

Cloud Computing


Cloud Computing Definition Cloud computing access the application of internet to utilize the Internet services. This enables us to create, create, and fix online business applications. Clouds can be limited to an Enterprise Cloud and available to many Public Clouds or a combination of both Cloud Hybrid. Cloud computing relies on sharing resources to ensure sustainability and scale economies. In this 21st century, the IT world has progressed up to the extent that, now users can access internet services on lightweight mobile devices like smart phones. The question arises how all this has become possible without using the powerful machines? The answer [...]

Intel 8255A – Programmable Peripheral Interface Pin Diagram


Intel 8255A - Programmable Peripheral Interface Pin Diagram Intel 8255A - Programmable Peripheral Interface used when we want control more than eight peripheral device. Suppose we want to control various device at a time like keyboard, printer, 7 segment display etc. then we need eight data bus of microprocessor at a time but here we have three peripheral so we require eight data bus for the keyboard, eight data bus for the printer eight data bus for the seven segment display then here we required 24 data bus that is not possible to control by the any processor so we required [...]

Intel 8255A – Programmable Peripheral Interface


The Intel 8255 (or i8255/onkyo tx 8255) Programmable Peripheral Interface (PPI) chip was developed and manufactured by Intel for the Intel 8080 microprocessor in the early 1970's. The 8255A is a programmable universal I / O device that allows the transfer of I / O data to an I / O interrupt when needed. It can be used with almost any microprocessor. It consists of three bidirectional 8-bit I / O ports (24 I / O lines) that can be configured as needed. Ports of 8255A The 8255A has three ports, PORT A, PORT B, and PORT C. Port A contains [...]

Arduino is an electronic platform that is combination of hardware and software. It is an open source software and software company, a community of projects and users that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices and interactive objects that are physically and numerically appropriate to control. Its products are licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL), so any Arduino can manufacture boards and distribute software. Arduino boards are available in pre-assembled form or as a kit commercially. Arduino boards use a variety of microprocessors and controllers. The [...]


IoT Based Patient Health Monitoring System using ESP8266 & Arduino


Patient Health Monitoring System using ESP8266 & Arduino With many new health technology companies, IoT is rapidly revolutionizing the healthcare industry. In this project, we developed an IoT-based patient health monitoring system with ESP8266 and Arduino. The IoT platform used in this project is ThingSpeak. ThingSpeak is an open source Internet application (IoT application) and an API for storing and retrieving data using HTTP over the Internet or a local area network. This IoT device could read the pulse rate and measure the ambient temperature. It continuously monitors the pulse and the ambient temperature and updates them on an IoT platform. [...]

8051 Microcontroller Timers and Counters


A timer is a special clock that is used to measure time intervals. It is a device that counts down from a certain time interval and is used to generate a delay. The timer can be used on an internal clock or from an external source. A meter is a device that stores (and sometimes displays) the frequency with which a particular event or process has occurred relative to a clock signal. This counts events that take place outside the microcontroller. In electronics, counters with register circuits, such as a flip-flop, can be implemented quite easily. Using the timer and the [...]

Description In this tutorial we understand how to interfacing l293d with 8051 micro controller. The l293d is motor driver IC which drive the DC gear motor through the 8051 micro controller. The interfacing of L293D can be understand with the help of any application, so here we understand with the help of motor driver program. Program to interfacing of L293D with 8051


Interfacing of Seven Segment Display with 8051


Introduction In this tutorial we will learn about the interfacing of seven segment display with 8051 controller. Before interfacing the seven segment we must be know about the types of seven segment and their controlling logic.As we know 7 segment are two types common anode and common cathode. In common cathode LED is glow by positive logic (1) and in common anode type it operate on low logic (0). Required circuit component: Microcontroller - AT89C52 7 segment LED Display (Common Cathode) Resistors -(330R) - {R1 to R8} Crystal oscillators - (11.0592MHz) Capacitors-(2)-33pf -{C1 to C2} Algorithm We want to display digit (0-9) [...]
