GSM module was used for receiving short message service (SMS) from user�s mobile phone that automatically enable the controller to take further action like switching ON and OFF electrical applications such as fan, air- conditioner, light etc. The system was integrated with microcontroller and GSM network interface using arduino.orduino software was utilized to accomplish the integration. The system is activated when user sends the SMS to the controller at home (regarded as Smart Home). Upon receiving the SMS command, the microcontroller unit then automatically controls the electrical applications by switching ON or OFF the device according to the user�s order. In other word, it reads message from the mobile phone and respond to control the devices according to the received message. � Research India Publications.EnglishOctober University for Modern Sciences and ArtsUniversity for Modern Sciences and ArtsMSA Universityجامعة أكتوبر للعلوم الحديثة والآدابArduinoCommandControlGSMImplementationMessageSwitchingArticle
