Accelerated IOT using NodeMCU

ESP8266 Wifi module, made by a privately held company in China called Espressif, is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to a WiFi network. ESP8266 module comes pre-programmed with an AT command set firmware that delivers quick and powerful programmability out of the box. In addition,

Rising trend in JavaScript: React Js

React is built around the concept of components. This is in contrast to frameworks like Angular and Ember, which use two-way data bindings to update the HTML of the page. React is easier to learn than Angular and Ember – it is much smaller and plays nicely with jQuery and other frameworks. It is also

Smart Contracts making Blockchain Technology Smarter

One of the biggest advantages of Blockchain as a technology is that it is a decentralized system and eliminates the need for an intermediary, and the costs and conflicts associated with it. This combined with the speed, low cost and security makes Blockchain a preferred choice of Governments, Banks and Organizations when compared to traditional

Beacons – Connecting with the Physical World

Beacons are a low-cost, easy-to-use piece of hardware that run on batteries and use low-energy Bluetooth (BLE) connections to transmit messages or prompts directly to a smartphone or tablet up to 50 meters away. Beacons are one-way transmitters; they detect nearby devices in order to send them messages, but the target devices don’t send information

Internet of Things – Few Challenges

Few doubt that smart devices are the next technological revolution. The next generation of connected appliances is already starting to create the Internet of Things (IoT), and to connect users to their devices in ways that were impossible only a few years ago. However, in the middle of new conveniences and wonder, the IoT also

Internet Of Things – Connecting everything

The new rule for the future is going to be, “Anything that can be connected, will be connected.” The basic idea is that IoT will connect objects around us (electronic, electrical, non electrical) to provide seamless communication and contextual services provided by them. The IoT allows objects to be sensed or controlled remotely across existing

Blockchain –Use Cases besides the Financial Industry

A blockchain is a decentralized shared database or ledger technology that records transactions in blocks across a decentralized network without the need for a middleman or intermediary. Each block in the blockchain contains a timestamp and a link to a previous block in the chain. Once recorded, the data in a block cannot be altered

PIC18F4520 Timer Programming

Timers are the most essential peripheral for a microcontroller and every controller provides a provision for using them. They are mostly used for exact delay generation. Timers are also used in various other operations like PWM signal generation, auto-triggering of several other peripherals etc. To put it simply, timers may be thought of as a

PIC16F1829 UART Programming

Today, many PIC microcontrollers include a Universal Synchronous/Asynchronous Receiver Transmitter (USART) module. We can configure this module as follows: a Full-Duplex asynchronous system that can communicate with peripheral devices, such as CRT terminals and personal computers a Half-Duplex synchronous system that can communicate with peripheral devices, such as A/D or D/A integrated circuits, serial EEPROMs,
