My project is:
1. A motor is interfaced to a pic 18F.
2. The user must be able to send an sms in order to on/off the motor.
How can I do this? I am just starting in this area. And I would appreciate your valuable suggestions and resources. :smile:
 

Hi,
First thing is that you have to buy a modem(e.g. SIMCOM or Wavecom), then start communicating with the modem from your system through UART by AT commands.
Then you have to program your Pic, which can automatically communicate with modem and do your need

But you can get all the information in this forum itself, surf it thoroughly
 

Using a modem will be costly for me. Is there any way without using modem to communicate with a phone?
 


ok.thanks. I found that its not possible to receive sms in a pic without using modems.
 

ya. Now Iam trying an alternative. To receive sms via pc and then transmit it to the controller.
 

@areeckal
Even for PC you will need a GSM modem. There is no way that you can do it without modem.

As for your topic title "How to send an sms from mobile phone to pic", it is very easy, Type your SMS and press Send button :)

(sorry, could not resist) :lol:
