In this tutorial we’ll learn how to create a very basic Blockchain with Python. We will create a Blockchain with just 30 lines of code! The aim is to introduce you to Blockchain programming without getting into inessential details. You should already know fundamentals of Blockchain, if not then you may want to read this… Continue reading Creating Your First Blockchain with Python
The temptation to earn Bitcoins is understandable as Bitcoin is valued as world’s most expensive currency at current rates. But who mints Bitcoins? How are they distributed? and most importantly how can you earn them? these are the questions we will answer in this beginner’s guide to bitcoin mining. But let me give you a… Continue reading A Beginner’s Guide to Bitcoin Mining : Learn Blockchain
Proof of Work (PoW) is a consensus algorithm used in the original Bitcoin implementation. In a Blockchain system new transactions are periodically added by packaging these transactions in a block. This block is then added to the Blockchain. Please read What is Blockchain Technology if you don’t already know. Background Users send each other digital… Continue reading Proof of Work Explained Simply : Learn Blockchain
What is blockchain technology? is perhaps the most buzzing question in tech right now. A blockchain as the name suggests is a chain of blocks. Each block contains some information; a blockhain can store complete information about a financial transaction, a contract or a medical record. Important property of blockchain is that the data stored… Continue reading What is Blockchain Technology?
MapReduce is a great approach to problem solving. It is very popular too, but MapReduce examples other than word-count are scarce on the web. This article describes MapReduce problem solving that is beyond word-count.
Arduino uses asynchronous serial communication to send-receive data to and from other devices. Arduino Uno supports serial communication via on-board UART port and Tx/Rx pins. Generally this transmission happens at 9600 bits per second which is termed as baud rate.
Arduino pushbutton example shows how to read a pushbutton with Arduino Uno. Pushbuttons (also spelled push-buttons) are widely used in calculators, phones and appliances. It closes the circuit when pushed and keeps it close until it is pressed. As soon as you release the button the circuit is open again. Here, we are going to… Continue reading Arduino Pushbutton Example : Learn Arduino
In this article we’ll learn displaying hello world on LCD; Interfacing 16×2 LCD with Arduino Uno and display some text on it. Writing Hello World pleases the gods of any new programming language that you want to learn. But in case of Arduino it is the LED blinking program that is generally written first. Any… Continue reading Displaying Hello World on LCD : Learn Arduino
LED Blinking on Arduino Uno should be your first Arduino project. Arduino Uno has an on-board or built-in LED, in this project we will see how to blink it. Parts you will need: An Arduino Uno Steps: Connect Arduino with your computer. Download, install and open Arduino IDE. (See how) Within IDE chooose File Menu… Continue reading LED Blinking on Arduino : Learn Arduino
Arduino is an open-source hardware prototyping platform. It is widely used today in electronics projects because it is easy to learn, simple in design, well documented and cheaper. We call it platform because it is both hardware circuit as well as piece of software, the IDE. It also has its own programming language. All these… Continue reading An Introduction to Arduino Platform : Learn Arduino
