2. DESCRIPTION
• The project is designed to control the speed of an
induction motor such as fans, by using android
application device.
• In home automation application, convenience of
remotely controlling the speed of the fan is
achieved.
• Android Mobile or any device act as a transmitter
through Bluetooth, which is then received by
Bluetooth receiver (at the receiver end) interfaced
to a Arduino Board.
5. Arduino UNO
Arduino is an open-source
electronics platform based on
easy-to-use hardware and
software. It's intended for
anyone making interactive
projects.
6. Blutooth Module
3.3V Device with standard 5V DC
Power source.
Can also support SPI Protocol,
pins are made available.
Low power consumption, Low
cost.
Has high-performance wireless
transceiver system
Can be used to interface with PC,
Mac or Android phones/tablets.
Works with any microcontroller
with Serial connectivity.
7. Opto-couplers are made up of a LED and a light sensitive device,
all wrapped up in one package
no electrical connection between the two devices
The light sensitive device may be a photodiode, phototransistor, or
more esoteric devices such as thyristors, triacs etc.
