Abstract
Sending messages using mobile technology is believed to be the latest trend. Because of its popularity, so applied to each sector. Siemens format that used to receive and transmit data module known as PDU (Protocol Data Unit). In the module called AT Command and use the AVR ATmega8535 microcontroller. This project describes how to design and create a system that can make motorcycle owners to feel secure when left on his motorcycle in a parking lot or in a state not used. Control is done using a microcontroller linked to mobile phones through the facilities of SMS (Short Messages Service). A device can secure our motorcycles with SMS. Sending SMS from your mobile phone in the previous system if the microcontroller will send the AT Command, then the message is received by the mobile user. The design consists of designing electronic circuits, data cable, and a microcontroller. For communication between mobile phones and microcontrollers, used in serial communication. To design the software used BASCOM. This language is used in programming the microcontroller.
Keywords : microcontroller, AVR ATmega8535, AT command, PDU mode
Pendahuluan
Peranan elektronika disegala bidang menjadi semakin besar diabad ke dua satu ini. Bermula dari penerapan rangkaian elektronika analog, kemudian digital dan kini hampir semua peralatan menggunakan sistem mikroprosesor. Pada masa sekarang ini penggunaan mikrokontroler semakin meluas. Banyak sekali peripheral, mainan anak, sistem kontrol industri maupun rumah tangga dan lain-lain menggunakan otak mikrokontroler.
