Introduction: Home Automation System Using Smartphone and Bluetooth

Hello everyone welcome to "Techno-E-result", Therein tutorial I will show you how to make Nursing home Automation System Using Smartphone And Bluetooth. For this project we are going to Practice Arduino Nano Eastern Samoa a microcntroller and hc-05 bluetooth module for Conncetivity purpose. The Blynk app are used to ascendence the hole system of this imag, And then without wasting away metre let's get cracking...........

Step 1: MATERIAL Necessary

Step 2: CIRCUIT DIAGRAM

I make this Tour in "Hands-down EDA" and I also make a PCB Layout of this project. Thusly you can easily give the circuit &adenosine monophosphate; PCB.

Next PCB

NextPCB is a pinched-quality PCB Manufacturer. With professional PCB manufacturing capabilities, our PCB engineers with to a higher degree 10 years of experience will treble-check your engineering files.

NextPCB is certified by IATF16949, ISO9001, ISO14001, UL, CQC, RoHS and REACH; more importantly, we handle the whole appendage including the PCB prototype, PCB manufacturing, PCB assembly, testing, and last shipment. We are capable of collecting BGA, Little-BGA, QFN, and other leadless package parts. We also have an online parts shop, you can choose any parts you need.

If you are need to form PCB Adam direct the NEXT PCB

Step 3: LET'S Shuffling PCB

Follow the following process for Making PCB Using Tonner Transfer Technic.

  1. Take a Single Sided Copper color Clad PCB Control panel
  2. Cut the PCB as per PCB Layout
  3. Remove the dirt & rust from the PCB aside victimization wire scrub or sand paper
  4. Place layout mark on PCB & Heat the PCB with the help of Iron for 5-10 Min
  5. Take water in the container & artful the PCB into the water for 5 min
  6. Easy remove the paper from the PCB
  7. Now take 2-3 snog of ferrite chloride powderize in container with water
  8. Deep PCB into the solution for 5-10 min for etching process
  9. Later etching completed just the unrestrained tonner from the PCB
  10. Practise The PCB with the help of PCB drill machine
  11. Now place app components on PCB &adenosine monophosphate; Solder It
  12. In this way the PCB plank is completed.

Step 4: BLYNK APP INSTALLATION & SETUP

Countenance's Setup the BLYNK app

  1. Put in Blynk App from google caper stock.
  2. Create Account On Blynk.
  3. Create New Propose.
  4. You volition get Tocken on your E-Mail.
  5. Give Name to Project.
  6. Select Device & Connection Type &A; click on Make up Release.
  7. Select Bluetooth, then add together 8 buttons.
  8. Give name to Buttons.
  9. Set the Pins.
  10. The app setup is completed

Maltreat 5: ARDUINO CODE

  1. Add Blynk library in your Arduino IDE
  2. Sketch-Include Depository library-Manage libraries-Type Blynk-Install
  3. Copy Pursual cipher & Upload to Arduino Nano (Remove Bluetooth Module)
/*  * Hello Friends Welcome To Techno-E-Solution  * Here is the Arduino Code for Home Automation by Techno-E-Solution  */  #define BLYNK_USE_DIRECT_CONNECT  // You could use a spare Hardware Serial on boards that have it (like Mega) #include <SoftwareSerial.h> SoftwareSerial DebugSerial(0,1); // RX, TX  #define BLYNK_PRINT DebugSerial #include <BlynkSimpleSerialBLE.h>  // You should get Auth Token in the Blynk App. // Die down to the Project Settings (nut icon). woman auth[] = "AuthToken";  void setup() {   // Debug comfort   DebugSerial.begin(9600);      pinMode (12, OUTPUT);   pinMode (11, OUTPUT);   pinMode (10, Yield);   pinMode (9, OUTPUT);   pinMode (8, End product);   pinMode (7, Yield);   pinMode (6, OUTPUT);   pinMode (5, OUTPUT);    pinMode (12, LOW); // Set All Pins Low Beacause At The Protrusive All Relay race get ON, Results In Completely load    pinMode (11, LOW); // Connected Across Relay Mental faculty Get Turn On    pinMode (10, LOW);   pinMode (9, LOW);   pinMode (8, Low-pitched);   pinMode (7, LOW);   pinMode (6, Insufficient);   pinMode (5, LOW);      DebugSerial.println("Waiting for connections...");    // Blynk wish form through Serial   // 9600 is for HC-06. For HC-05 default pelt along is 38400   // Do non read or write this serial manually in your outline   In series.get(9600);   Blynk.begin(Serial, auth); }  void loop() {   Blynk.operate(); }

Step 6: FINAL CONNECTION

  1. Adjust LM2596 to 5V and Tie to the PCB.
  2. Connect Relay mental faculty to PCB.
  3. Give Power Provision.
  4. Touch base AC Lode as per above electric circuit Cirgram.

Footmark 7: DEMONSTRATION

  1. Open Blynk app.
  2. Turn On Bluetooth.
  3. Click along Bluetooth button & select hc-05
  4. Now Smartphone get Connected to the Home Automation System.
  5. Now you can control 8 Warhead away using your Smartphone.
