This post is about how to use the Micro SD Card Reader with the Arduino. This will allow you to store the relevant data into a Micro SD Card. We’ll also be discussing how a Micro SD Card works. Micro SD Card Micro SD Cards or Secure Digital works on Flash Memory ( Click here […]
Quantum Computing – IBM Quantum Cloud
In this guide, I will introduce you to the world of Quantum Computing. Let us start with the basics. “If you try to explain Relativity to someone by starting with space and time, you may be greeted by blank stares. A better way to start is as Einstein did, that Relativity follows from a simple […]
Guide for using RFID Module with Arduino
Radio Frequency Identification or RFID is a wireless system that uses electromagnetic fields to transmit data from one object to another, without the two objects touching. You might have used RFID cards before or seen its implementation ( Ex- Metro Stations ). There are various kinds of RFID tags available like the one shown below. […]
Circuit Switching Vs Packet Switching
This course will introduce you to the basics of Computer Networking and how data transmission works. Communication Links It is a communication channel that connects two or more communicating devices. One of the most common means of communication links is a pair of wires, also known as cable. Other channel include Coaxial Cable, Fiber Optics, […]
Nmap Tutorial
What is Nmap ? Nmap is a tool that can be used to scan networks, servers, routers. It is a security scanner used to discover hosts and services on a computer network, thus creating a “map” of the network. To accomplish its goal, Nmap sends specially crafted packets to the target host and then analyzes […]
Memories of an Arduino
“Computers are incredibly fast, accurate and stupid; humans are incredibly slow, inaccurate and brilliant; together they are powerful beyond imagination” There are 3 types of memories in an Arduino : Flash SRAM EEPROM Flash Memory It is where the Arduino sketch image is stored. Non-Volatile , i.e. , information persists after the power is turned […]
Embedded Systems – Linux Kernel Module Programming
“Do you pine for the nice days of Minix-1.1, when men were men and wrote their own device drivers ?” – Linus Torvalds What is a Kernel Module ? Modules are pieces of code that can be loaded and unloaded into the Kernel upon demand. Now, we get to the real action, where […]
Embedded Systems – Storage Conditions
Memory is simple electronic system, consisting of millions of individual cells which have a unique address which stores 1 bit of data- either a ‘1’ or a ‘0’. Storage Conditions As we all know, Embedded Systems have limited physical resources. Hard drives are faster than Flash memories but are bulky, have rotating parts, […]
Embedded Systems – Booting Process
Steve Jobs once said, ” You can’t connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future. You have to trust in something – your gut, destiny, life, karma, whatever ” The same applies to the world of electronics. […]
Embedded Systems – Introduction
You’ve no doubt heard of Linux! Linus Torvalds , the inventor of Linux, was quoted as saying ” Linux will never run on anything but a PC with an IDE hard disk since that is all that I have” Embedded Linux is a type of Linux operating sytem / kernal that is designed to […]
