How to Interface RFM69HCW RF Module with Arduino for Wireless Communication
The RFM69HCW is a cheap easy to use radio module that operates in the unlicensed ISM (Industry, Science and Medicine) band similar to the nRF24L01 RF Module that we have used in previous projects. It can be used to communicate between two modules or can be configured as a Mesh Network to communicate among hundreds of modules that makes it a perfect choice for building inexpensive short-range wireless networks for sensors used in home automation and other data acquisition projects.

LED Display Board using Arduino

In this DIY session we are going to use a 32×16 LED dot Matrix display module which is also known as P10 LED Display Module to display a scrolling text by using Arduino UNO. P10 modules can be cascaded to build any size of the advertising board.

Automatic Bottle Filling System using Arduino

Here we are going to design a prototype for Automatic Bottle Filling Machine using Arduino Uno, conveyor belt, solenoid valve, IR sensor, and Stepper motor. Belt conveyor is driven by a stepper motor at a constant preset speed. The stepper motor will keep driving the belt until an IR sensor detects the presence of a bottle on the belt. We used the IR sensor as an external trigger. So whenever the IR sensor goes high it sends a trigger to Arduino to stop the motor and turn on the solenoid valve.

Overcurrent Protection Circuit using Op-Amp

Arduino Home Automation using Acoustic Connectivity powered by Chirp

So in this project, we build an Acoustic Home Automation Device in which we will be able to control this smart device without using any wireless connections like Wi-Fi or Bluetooth. We will use Actions for Google and Dialogflow to build a test application for our Google Assistant to make it play encoded audio (Chirp). This audio will then be captured by the Arduino nano BLE sense board running the Chirp Arduino Program, based on the message encoded in the data the Arduino board could perform any action like toggling an AC load controlling the RGB LED, etc. It might sound like a lot, but it is relatively simple.

Alexa Controlled Home Automation using Arduino and ESP-01 Wi-Fi Module

Home automation has become very common now days and people are using IoT to automate everything in their home. Here in this tutorial we will use a Real Amazon Echo dot speaker and create a custom skill to control AC home appliances like lights, Fans, TVs, Sockets using an Amazon Echo dot Speaker. Here we will use Arduino UNO and an ESP8266-01 Wi-Fi module to connect Echo dot speaker with AC appliances. After this tutorial, you will be able to control any appliance though Alexa.

DIY Arduino Wireless Programming Shield using Bluetooth Module
While doing projects using Arduino, we always need to connect Arduino to PC in order to upload the program in it. But sometimes it is very uncomfortable to always connect the board with PC as if it is a robotics project then you always have to move the robot near to labtop to re-program it. This problem can be solved by programming the Arduino wirelessly. So here we are building a circuit to program the Arduino wirelessly using Bluetooth module HC-05.

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.
