Hello!
I am a 5th Yr. Computer Engineering student. As a 5th Yr. Computer Engineering student we are required to have a senior project in order for us to graduate. My senior project is entitled "Remote control using cellphone".
The object of my project is to send remote control commands using a cellphone (SMS). The usser sends command using the a cell phone. The device to be controlled is to be connected to another cellphone via an interfacing box. The cellphone connected to the device that is to be controlled will extract the SMS recieved by the cell phone and determine if this is a valid command. If it is a valid command it will output a cooresponding control signal to the device being controlled.
I have learned that the cellphone communicates with external devices via its port serially, using the RS232 format at 9600 baud rate. The problem is the voltage level of the pin. I dont know what voltage level will be considred high logic and what voltage level will be considered low logic. Another problem is the microcontroller to be used in this project. The only microcontroller I am familiar with are the Microchip PIC series microcontroller, specifically the PIC16F84A. Can I use the PIC16F84A for this purpose? If yes, how am I to program that pic? Do you have any source codes?
Hope somebody could help me (anything as long as it is related to my project)....
Thank you... and Merry Christmas to ALL!!!!!!!!!
