hi M. Khalil,, our project is to control the on/off of ligths and appliances. we will send message to the gsm modem an then the gsm is the one that is connected to the PIC16f877a. after that the PIC is connected to the relays that is connected to the appliances or ligths. after that the gsm will send a message to the phone that the command has been executed. its as if it will upadate the phone that this particular applaince is turned on… we will not use lcd. just the phone, GSM modem and the PIC…
we are having a difficult time in the programming part
