Wear Dreamers

We are the dreamers

                    with a dream of flying high

We try to touch the sky,

                    And go to a boundless world.
We believe in what we are,

                    We do what we can.

Nothing can stop us,

                     because we are the dreamers.

              

Our dream is to built an INDIA,

                       which world will know.

We tempted to achieve our goal,

                       And eager to score it.

 Everybody will know us,

                       because we are the dreamers.

              

              

We dream to reach beyond the universe,

                       To the house of stars.

We and our knowledge,

                       that will make our dream true.

We never stops

                       because we are the dreamers.

Take a tour of my Home Automation System- Uncut Video

    I have uploaded a uncut video of my home automation system . Please share your feedbacks and subscribe to my youtube Channel.

Automated Audio Controller based on Arduino Pro Mini

These are some of the images of the Audio Controller Module that i have designed for my Smart Home to provide audio feeds from many devices to one or many output audio channels. It's a simple selector not a mixer. Later on I will pro

CRC16 Calculator using JAVA

           CRC codes are numerously used fro error checking purposes. So many times working around Embedded Devices you will find CRC used in different communication protocols. So guys here i have written a piece of code to generate CRC16 using provid

Calculate Energy Usage using Current Sensor ACS712 30A

                 This is a simply cheap solution to calculate Energy consumed by your gears..But still the accuracy i have not tested..Buy a

Measure Distance using Ultrasonic Sensor (HC-SR04) for Robots using Arduino

                 This is simple example to use HC-SR04 ultrasonic transceiver to calculate the distance of a object.  This is simply done by sending a pulse from the module and receiving the echo by it. Then the distance is calculated by considering the time elapsed to receive the echo.

Use TRIAC as Relay

           Mostly we all use relays to control AC loads as they are widely available and cheaper.. But things becomes complicated as they are bulky and makes noise......everyone knows where i have placed my

Making PCB at Home

              By using the conventional APBS which are available in market ,making circuits becomes messy as you have to do all the connections using the wires and of-course it looks ugly.So to avoid that and get a beautiful circuit of your own at a cheaper cost i  am providing this article.


To make own PCB we need Copper cladded board,Hydrochloric acid,hydrogen peroxide,one driller,laser printer,Software to make the circuit design,magazine paper ,one press iron and water.I  have given where can you get all the materials.Now all the processes step by step..

Screenshots of my SmartHome Android App..

Guys here are some screenshots of the Android App used to control devices in my smart home that i am working on....

Getting started with ESP8266-01

         

                 Wi-Fi.....Sounds good right....What if you can make your next project with Wi-Fi interface and with cheaper cost even if lower then ENC28J60 based Ethernet module.....I am sure you will be the happiest one....So how is that possible..? Ya you red right you can get Wifi at cheper price then ENC28J60 and that's by using ESp8266 Wi_Fi modules.

               These modules are extremely cheaper and easy to use. In this post i will post about how to get started with ESp8266-01 modules.

3G Connectivity With Raspberry Pi using Huwaei E303 Dongle

  Hi Guys. In this post we will see how to provide internet connectivity to Raspberry Pi using 3G USB dongle. This comes handy in many cases.The internet connection will be provided by a Huawei E303 USB 3g dongle on the vodafone network Odisha.

Setup

                            Power Source -------->RPI--->(USB) 3g Dongle

         

  The USB port of the PI doesnot have enough power to provide to a 3G dongle so if you plug directly the dongle onto the Pi the Pi may behave unwantingly which can be avoided by using an externally powered USB hub. I Raspbian Wheezy on Raspberry Pi. Next is after connecting the dongle to the Pi is to check if that has been detected by Pi. To get a list of USB connected devices type :

   $ sudo lsusb

RFID With Arduino

    Hello visitors..... Its been a hard time working with my home automation system..And this week I was working with access control system. The end goal was to allow only the authorised user to use my home automation system as well as my system can keep track of the users in and out activity. It now knows exactly i am inside or not or one of my friend is inside. For that i have used RFID Reader as well as Mobile App access token......

    Today with this post i will share how to Interface EM18 RFID reader with Arduino. EM18 is really simple to Interface.

PIR Sensor with Arduino

                           PIR sensors are really simple and easy to use as well as cheap motion detection sensor. The feature that it is easy to interface with any microcontroller makes it widely usable. Here i am providing a simple Arduino sketch to interface it with Arduino.

Send note as E-Mail from PC application using JAVA

Hi guys. This is my first post using my home management system. Here i am going to post codes on making a simple app that can be used to send email with notes to your own mail. this comes handy when you are working on office or other PC and you want to save something interesting, In that scenario hopefully you will not be interested to open your mobile and get on typing. Hope this helps. But to use this you need to enable IMAP and POP in your mail settings.

** Make sure yo change your mail username and password in saveNote.java File.

From now on i will be providing codes on bitbucket only.
