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.
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.

Arduino HM-10 BLE Module Tutorial
The HM10 has become a very popular Bluetooth 4.0 BLE module. The HM10 is a Bluetooth 4.0 based module only, so it will not connect with Bluetooth 2/2.1 module such as HC-05, HC-06 and other Bluetooth modules. The HM10 is controlled via AT commands sent over the serial UART connection. HM-10 is a Bluetooth Low Energy (BLE) module, to know more about this module, check out the HM-10 BLE datasheet.

What is Switch Bouncing and How to prevent it using Debounce Circuit
Simply, we can say that the switch bouncing is the non-ideal behavior of any switch which generates multiple transitions of a single input. Switch bouncing is not a major problem when we deal with the power circuits, but it cause problems while we are dealing with the logic or digital circuits. Hence, to remove the bouncing from the circuit Switch Debouncing Circuit is used.

In previous tutorial we have discussed about MQTT Protocol and installed local MQTT server on our Raspberry Pi for controlling the GPIO locally. But the drawback of local MQTT server is that we cannot control the GPIOs from anywhere in the world, it only provides services locally. But if this MQTT server is hosted on some cloud then any appliances connected to Raspberry Pi can be controlled globally.

DIY Arduino Based Color Sorter Machine using TCS3200 Color Sensor
Here in this tutorial we will make a color sorting machine using a color sensor TCS3200, some servo motors and Arduino board. This tutorial will include the sorting of colored balls and keeping them in the relevant color box. The box will be in the fixed position and the servo motor will be used to move the sorter hand to keep the ball in the relevant box.
