Introduction:
In this
project we control all the home
appliances from PC .This project is very important for home, office, shops etc.
The most important use of this project is in the industries where you can
control thousands of appliances from one single PC. it gives you reliable results of controlling a lot of devices
.
The other big advantage of this project is
a good power management. In case of any
failure in the power system early recovery is possible
and less time will be waste.
In such project you can control any type
of Electric powers, for example you can control power of small industries, big industries, power
plants etc.
There are a
lot’s of application of this project in the industries side.

Objectives :
In this project we are controlling home appliances from PC .The software use for Developing an HMI (Human
machine Interface) is VB.NET (visual basic dot net).
We send data from vb.net HMI to Arduino microcontroller
.The arduino receive the data serially
and sending command to the output pins which control the relays, the relays control
the appliances.
In
this project we use two computer languages the 1st one is Visual Basic Dot Net
(VB.NET) and the 2nd language is
C++ .In VB.NET we design HMI which shows
the whole system to control with a single click. The HMI continuously monitored
the whole system .The C++ language is use in the Arduino Command Line Interface
(CLI) .From this language we control the whole circuits.
Both the languages will be serially connected to
each other.
Components:
• PC/Laptop

Relay Module:
I made this
module my own but you can also buy it from market.I will also be
make a blog on how to make your own PCB(Printed circuit board).This module have
4 channel .i mean that you can control four different devices from this
module.In following components are used in this circuit .
1:Four 12 volts
relays
2:Four tipp 127
transistors.
3:Some diodes.
4:led.
5:DC socket.
6:Resistor.
7:Female header row .
8:Some wires.
Arduino Code:
int bulb = 13;
int fan = 12;
int tv = 11;
void setup() {
pinMode(bulb, OUTPUT);
digitalWrite(bulb, LOW);
pinMode(fan, OUTPUT);
digitalWrite(fan, LOW);
pinMode(tv, OUTPUT);
digitalWrite(tv, LOW);
Serial.begin(9600);
}
void loop() {
delay(500);
while(Serial.available() > 0)
{
byte incomingByte = Serial.read(); // Reads incoming byte from serial
if( incomingByte == '1'){ digitalWrite(bulb, HIGH);
Serial.println("bulb ON");
delay(100);
}
if( incomingByte == '2'){ digitalWrite(bulb, LOW);
Serial.println("bulb OFF");
delay(100);
}
if( incomingByte == '3'){ digitalWrite(fan, HIGH);
Serial.println("Fan ON");
delay(100);
}
if( incomingByte == '4'){ digitalWrite(fan, LOW);
Serial.println("Fan OFF");
delay(100);
}
if( incomingByte == '5'){ digitalWrite(tv, HIGH);
Serial.println("TV ON");
delay(100);
}
if( incomingByte == '6'){ digitalWrite(tv, LOW);
Serial.println("TV OFF");
delay(100);
}
}
}
