What is Industry 4.0? Nine Pillars of Industry 4.0
Industry 4.0 is the fancy name given to the fourth Industrial revolution. In this article, we will discuss about what is Industry 4.0 and how is it going to enhance the future of Industries? Why such a buzz about it? Why failing to adopt it may kill your business? Let us take a look. It is sometime spelled as Industrie 4.0, this is the German translation of Industry so both can be used interchangeably.
Ever since I started to work with the ESP Wi-Fi Modules, I always wanted to build a smart Wi-Fi socket that enables me to control my AC loads wirelessly through smart phone. While products like these are already available in the market, like the popular Moko WiFi Smart Plug or Sonoff, they are a bit expensive and on top of that it doesn’t give you the joy of building your own. So, in this project I will show you how you can build your very own Smart plug using ESP8266 Wi-Fi module. The device that we built can easily be plugged into any exiting AC socket and then on the other end you can connect the actual load simply by plugging it into this socket on our device. After that just keep the main switch of your socket always on, and you can control your Load directly from your Smartphone. Fun right? Check out the project at below link ….
Driverless LED Lights
The major problem with the traditional high power AC to DC switching LED drivers is the power loss associated with it. These traditional AC LED drivers use switching topologies and resistors to control the LED current, this switching causes heat which reduces the efficiency of the system. Also this additional circuitry leads to the increase in overall cost of the Light bulb. This is why in our previous article we discussed about a low-cost LED driver system and even built one to test its performance.
DIY Pick and Place Robotic Arm using ARM7-LPC2148 ARM Microcontroller
In this tutorial we will use a 3D printed robotic ARM that was built by following the procedure in thingiverse. The ARM uses 4 servo motor for robotic ARM movement. If you do not have a printer, you can also build your arm with simple cardboards like we built for our Arduino Robotic Arm Project. For inspiration you can also refer to the Record and Play Robotic Arm that we built earlier using Arduino.

12V 1A SMPS Power Supply Circuit Design
In this tutorial we will cover how to build a 12v SMPS circuit that would convert AC mains power to 12V DC with a maximum current rating of 1.25A. This circuit can be used to power small loads or even be adapted into a charger to charge you lead-acid and lithium batteries.

The basic idea of this Arduino Water Fountain is to take an input from any external sound source like mobile, iPod, PC etc., sample the sound and break it down to different voltage ranges, then use the output to turn on various Relay. We first used a condenser mic based sound sensor module to perform on the sound source to split the sounds into different voltage ranges. Then the voltage will be fed to op-amp to compare sound level with a particular limit. The higher voltage range will correspond to a relay switch ON which comprises a musical water fountain operating to the beats and rhythms of the song. So here we are building this Musical Fountain using Arduino and sound sensor.

What is Blockchain and how can it be used to keep your data secure
Today Human civilization is highly dependent on computers and other machines. Everything around us from a simple alarm clock, to a complicated online banking system, works based on the program written for it. But how dependable are these programs, it is okay to wake up late when your alarm clock fails you, but think about losing your life’s savings just because your banking system was compromised. In fact, an article from Forbes states that in 2017 banks have lost about $16.8 billion to cybercriminals. This puts a big frown on our face, if these programs are subjected to loopholes, How can we trust them to drive our future autonomous cars? How can we trust them to automatically administer drugs and help take critical decisions in biomedical field?

Electromagnetic compatibility in Electric Vehicles
When current passes through a conductor it creates electromagnetic fields and almost all electronic devices like TVs, washing machines, induction stove, traffic lights, mobile phones, ATMs and laptops etc., will emit the electromagnetic fields. Fossil fueled vehicles also suffer from Electromagnetic Interference (EMI) – The ignition system, starter motor and switches cause broadband EMI and electronic devices cause narrowband EMI. But as compare to ICE (Internal Combustion Engine) vehicles, Electric Vehicles are combination of various subsystems and electronic components like battery, BMS, DC-DC converter, inverter, electric motor, high-power cables distributed around the vehicle and chargers, all these are working at high power and frequency levels which causes the emission of high-level low-frequency EMI.
