introductionOVERVIEW Vary the speed of DC motor according to the PWM. Use of seven segment display. Control by using GSM mobile.

Goals and Objectives To co-ordinate motor and other devices through DTMF. Effectively receive and transmit data via DTMF. Control of motor from anywhere in the world. Minimize time wastage.

Circuit Diagram

WorkingStarts from dials tone (connected mobile phone with DTMF

decoder) and dual tone (remotely mobile) as well as switches

Regulated power is given to each componentControl of motor using PWM techniquePressing the button of mobile then DTMF decoder

generates 4-digit code and the speed of motor can be controlled

These values can be displayed on 7 segmentWe connect two GSM mobileWhen we press the key of mobile phone 1, dtmf decodes it

to 0001, than speed of motor is 10% of rated speeed

ADVANTAGES

Control of motor from anywhere in world.Save power.User friendly.Fast effective & flawless service.High reliable and flexibility.Reducing cost.

DISADVANTAGES-If network is busy/fail then we can’t able to connect with

motor.

APPLICATIONIndustrial control.Access control.In irrigation system by using relay system.Can be deployed in remote car.

FUTURE SCOPE & CONCLUSIONGreat considering the amount of time and resources it

saves.It may be implemented in other projects such as weather

forecasting temperature updates.Future goal will be to design the speed control through

infrared.
