HELP ME, SMS controlled relay using PIC

[pazko1125]

hello everyone,

my project is this, a message should trigger a relay, i only need one relay for an alarm.

my problem is that i don't know how to read the message using PIC and what AT command should i use, what PIC should i use to read the SMS, what cellphone should i use? to be honest i have only a little experience about PIC.

so please could anyone help me realize this project. any tutorial or guide will be great help for me to understand on where should i begin. i also need a circuit diagram and program code if possible.

thanks in advance.

What do you mean by 'codes in using pic'? A ready made program?

Please have a look at the link:

P.S. Next time give more details, like your PIC type, your IDE and you up to this moment program you have written.

yes, if possible can u give me a ready made program. i seen a lot of sample program in the forum but really i can't understand the initialization, and how to send AT commands using PIC. i already tried sending AT commands using hyper terminal and it works and now my problem is on how to use the PIC to send AT commands. thanks for the links. hope you can help me.

Did you even look at the links above? Looks to me like 'ready made'...

Maybe you should start off by making a PIC do something simple like making an LED blink or something along those lines before trying to tackle sending/receiving serial port data....much less trying to talk to a cell phone. I mean... How far into PICs are you? How much stuff have you built? Have you answered any of the questions Ioannis asked two posts above? We don't know what you're dealing with...
