Hello friends welcome back to “Techno-E-solution”, In previous video we see how we can control the home appliances with the help of Smartphone & Bluetooth but there is no any manual control for the system, so In this tutorial we are going to make a Smartphone control as well as manual controlled home automation system with Complete details.

Let’s get started……………
Part one Of this project :-
Step 1: MATERIAL REQUIRED
The following material are used in the project
Electronic Components :-
- Arduino Nano
- Bluetooth Module (hc-05)
- 8-Channel Relay Module
- LM 2596 DC-DC Buck Convertor
- Red LED (5mm)
- Resistor (470E)
- Male – Female Berge Strip
- 2-Pin Block Connector
- Female-Female Berge Connector Wire
- Single Layer Copper Clad PCB Board
- Power Supply (12V, 1amp)
Hardware / Other Material :-
- PVC Switch Board
- Two way Switch x 8
- 5-Pin socket x 2
- PCB Drill Machine
- Mini Hack Saw
- Ferric Chloride
- Container
- Iron
- Photo Paper
- Laser Printer (Tonner Filled)
- Screw Driver
- Soldering Kit
Step 2: CIRCUIT DIAGRAM
For making Circuit & PCB I used Easy EDA Software, I Provide the PCB layout just print and use tonner transfer method to make PCB.
Step 3: LET’S MAKE PCB
Follow the following process for Making PCB Using Tonner Transfer Technic.
If you want to real PCB, I provide Gerber file below check it.
- Take a Single Sided Copper Clad PCB Board
- Cut the PCB as per PCB Layout
- Remove the dirt & rust from the PCB by using wire scrub or sand paper
- Place layout print on PCB & Heat the PCB with the help of Iron for 5-10 Min
- Take water in the container & deep the PCB into the water for 5 min
- Slowly remove the paper from the PCB
- Now take 2-3 spoon of ferrite chloride powder in container with water
- Deep PCB into the solution for 5-10 min for etching process
- After etching completed clean the excessive tonner from the PCB
- Drill The PCB with the help of PCB drill machine
- Now place app components on PCB & Solder It
- In this way the PCB board is completed.

Step 4: BLYNK APP INSTALLATION & SETUP
- Install Blynk App from google play store.
- Create Account On Blynk.
- Create New Project.
- You will get Tocken on your E-Mail.
- Give Name to Project.
- Select Device & Connection Type & click on Create Button.
- Select Bluetooth, then add 8 buttons.
- Give name to Buttons.
- Set the Pins.
- The app setup is completed
Step 5: ARDUINO PROGRAMMING
- Add Blynk library in your Arduino IDE
- Sketch-Include Library-Manage libraries-Type Blynk-
- Copy Following code & 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. // Go to the Project Settings (nut icon). char auth[] = "AuthToken"; void setup() { // Debug console DebugSerial.begin(9600); pinMode (12, OUTPUT); pinMode (11, OUTPUT); pinMode (10, OUTPUT); pinMode (9, OUTPUT); pinMode (8, OUTPUT); pinMode (7, OUTPUT); pinMode (6, OUTPUT); pinMode (5, OUTPUT); pinMode (12, LOW); // Set All Pins Low Because At The Starting All Relays get ON, Results In All load pinMode (11, LOW); // Connected Across Relay Module Get Turn On pinMode (10, LOW); pinMode (9, LOW); pinMode (8, LOW); pinMode (7, LOW); pinMode (6, LOW); pinMode (5, LOW); DebugSerial.println("Waiting for connections..."); // Blynk will work through Serial // 9600 is for HC-06. For HC-05 default speed is 38400 // Do not read or write this serial manually in your sketch Serial.begin(9600); Blynk.begin(Serial, auth); } void loop() { Blynk.run(); }
