SMS Controlled DC Motor

Description

This SMS-controlled DC motor is designed with the idea to use the mobile handset as a long-distance remote controller. The mobile sets are now a day’s used most widely and very commonly. The SMS can be sent to any mobile user of any service provider with no or a minimum charge. This system is designed using a GSM modem.

This SMS-controlled DC motor kit is the GSM modem is configured as a receiver. The SMS sent by the user is written in a particular format. The controller receives the message and decodes it and identifies the task to be done. To control the DC motor operation (speed and direction), we have to send just an SMS in a particular format, as soon as the SMS gets received by the microcontroller; it fetches the particular data from the SMS and controls the motor accordingly.

In the kit SMS controlled DC motor proper message is also displayed on the LCD for the same (Optional).In the motor interfacing part, we will be needed a geared DC motor, and L293D IC to interface the motor with the microcontroller. Any message to be displayed can be sent by SMS anywhere. To control the motor, the motor driver is used. The motor driver is interfaced between a microcontroller and the motor. The speed of the motor is controlled using PWM.
