ABSTRACT
Now a days there are large number of good-quality motors and there speed controls available in
the market but it is of cost effective. A speed control with both low cost and good performance
will be highly marketable.On the other hand, the wireless technology has a nature of low cost
and less environmental limitations. Combining these ideas together this concept of a High
performable low-cost low-loss wireless speed control of dc motor is developed.
As many of the industries use induction motors. So, controlling of induction motor plays a very
vital role. So,our project concentrates on controlling the speed of induction motor using Android
phone remotely by the help of the Bluetooth technology. We use Android application which uses
Bluetooth to connect to the Bluetooth modem of control circuit which is connected to the motor.
Bluetooth modem is interfaced with microcontroller. The Bluetooth slave modem receives the
command from the mobile phone. The Bluetooth modem sends the signal to the Microcontroller.
The Microcontroller decodes the signal and sends to the relays. Then, respective relay operates to
change the speed of Induction motor from 0% to 100%.
We are not only controlling the speed of the Induction motor, using feedback network we can
also detect the over temperature, high voltage, low voltage, MCB tripping on account of any
faults. And we are also adding an extra application which is very important in industries. That is,
monitoring of phase lines. Because these types of uncertainties like over temperature, high
voltage, low voltage etc are likely to happen in Industries. So, this project will be very helpful in
industries, house hold, shopping malls etc.

1. INTRODUCTION
The purpose of this project is to control the speed of ac as well as dc motor using microcontroller
and bluetooth with android phone .this uses PWM and resistance control technique to control
speed from 0% to 100%
Android is the software stack for mobile devices that includes operating system middle way and
key applications .Android boost a healthy array of connectivity options,includindg WIFI
,Bluetooth and wireless data over a cellular connections(GPRS ,EDGE and 3G) android provides
access to void range of useful libraries and tools that can be used to build rich applications
This project also uses pulse width modulation technique for controlling the speed of dc motor as
per requirement according to the duty cycle it uses PWM pin of arduino for that
purpose.Bluetooth module receives signal sent from android mobile hence as per our
programming motor operates.
Here we made two modes of operation: 1)manual and 2)wireless for better understanding the
difference between wireless and manual operations,respectively.Manual operation control by
voltage regulators used and fan speed control with five tap options.Similarly in same way same
voltage selector switch is operated by wireless by selecting Wireless mode using android app i.e
Bluetooth Controller.
Respective relays are used for both ac as well as dc motor to control the speed of motor means
we can select speed by either using the selector switch or by Bluetooth applications,Respectively

1. BASIC FUNCTIONS OF MAIN COMPONENTS
COMPONENT DESCRIPTION
BC 5473
(Transistor)
BC 548 is general purpose NPN bipolar junction transistor.
It is PNP epitaxial silicon transistor that originated with the metal based
BC108 family of transistor used for selecting modes.
Features:
 High breakdown voltage
 Current gain between 110 to 800Ma
RESISTOR The electrical resistor is a element that opposes the flow
of current. It is a passive two terminal electrical component that
implements electrical resistance as circuit element.
The current through the resistor is directly proportional to the
voltage across the resistors’s terminals. It limits the current flow
through the circuit.
LED A light-emitting diode (LED) is a two lead semiconductor light
source that resembles a pn junction diode, expect that an LED
emits light. When an LED’s anode lead by at least the LED’s
forward voltage drop, current flows. Electrons are able to
recombine with holes within the device, releasing energy in the
form of photons. This effect is known as electroluminescence, and
the colour of the light is determined by the energy gap of the
semiconductor.

DIODE Protect circuits by limiting the voltage (clipping and clamping)
turn AC into DC (voltage rectifier)voltage multipliers (e.g. double
input voltage) non-linear mixing of two voltages.
RELAY Switching devices in most of the control processes or equipment
regardless of whether they are electronic or electromechanical. All
the relays respond to one or more electrical quantities like voltage
or current such that they open or close the contacts or circuits. A
relay is a switching device as it works to isolate or change the state
of an electric circuit from one state to another.

PORT NO.3 (PIN AO –A5) : Port C is a 7-bit bi-directional I/O port with internal pull-up
resistors (selected for each bit). The PC[5:0] output buffers have symmetrical drive
characteristics with both high sink and source capability. As inputs, Port C pins that are
externally pulled low will source current if the pull-up resistors are activated. The Port
C pins are tri-stated when a reset condition becomes active, even if the clock is not running.
PIN NO. 3,5,6,9,10,11 use for pulse width modulation speed control
The Atmel AVR® core combines a rich instruction set with 32 general purpose working
registers. All the 32 registers are directly connected to the Arithmetic Logic Unit (ALU),
allowing two independent registers to be accessed in a single instruction executed in one clock
cycle. The resulting architecture is more code efficient while achieving throughputs up to ten
times faster than conventional CISC microcontrollers.
