Скачать или смотреть SMS Based Speed & Direction Control of DC Motor by KitsGuru.com | LGEC092

This kit SMS controlled DC motor (http://www.kitsguru.com/technology-ba...) is designed with an idea to use the mobile hand set as a long distance remote controller. The mobile sets are now a day’s used most widely and very commonly. The SMS can be sending to any mobile user of any service provider with no or a minimum charge. This system is designed using a GSM modem.

In the kit SMS controlled DC motor 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 a SMS in a particular format, as soon as the SMS gets received by the micro controller; 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 motor with the micro controller. 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 micro controller and the motor. The speed of the motor is controlled using PWM.
