please help make a listing for controlling the motor through sms with GPS / GPRS / GSM V3

please listings receive sms, read, and approved the process sms and delete sms :(

2013-11-04 15:40:24 sorry grey longtime not login to forum becuz i'm very busy...

yes grey...motor Controlling but without PWM...

thx for reply...i will try it... :) karaeng_android

Have you still working on this issue?
I write a sketch about how to control arduino by GSM module.
when I input the message by myself via serial port, it works fine, but l plug the module on the arduino
it won't work.And what I input is what module outputs. It has been bothering me for a long time.

[code]#include <Wire.h>
#include <Arduino.h>

#define S_IDLE 0
#define S_ATOK 1
#define S_GETMESSAGE 2
#define S_READMESSAGE 3

#define M_ATOK "OK"
#define M_GETMESSAGE "+CMTI"
#define M_READMESSAGE "+CMGR"
#define M_CALLREADY "Call Ready"
#define M_FLAG "DF" //DF the the flag to position the Command in the data recevied by Serial port.you also can change it using other flag.

char messageCMD[2]=""; //using to hold Command,for example,if the value is H8,stands the pin 8 will output a high level.
String comdata = "";
int gsmDriverPin[3] = {10,11,12};
int messageControlPin[7]={3,4,5,6,7,8,9};

void setup(){
Serial.begin(9600); // The rate should not too high.It's ralated with the delay time of reading data from the Serial port.
for(int i = 0 ; i < 3; i++)
{
pinMode(gsmDriverPin[i],OUTPUT);
}
digitalWrite(12,HIGH);
delay(1500);
digitalWrite(12,LOW);
digitalWrite(10,LOW); //Enable the GSM mode
digitalWrite(11,HIGH); //Disable the GPS mode
delay(5000);//need test
delay(5000);//need test
delay(5000);//need test
Serial.print("AT");
//Serial.write(0x0D);
Serial.print("ATE0"); // echo off
// Serial.write(0x0D);
delay(20);
Serial.print("AT+CMGF=1"); //Set the format of message to Text Mode
// Serial.write(0x0D);
delay(20);
Serial.print("AT+CNMI=2,1,0,0,0"); //Set new SMS message indications
// Serial.write(0x0D);
delay(20);
delay(100);
for(int i=0;i<7;i++)
{
pinMode(messageControlPin[i],OUTPUT);//Initial the controlled pin
}
}
void loop(){
String event_message="";
int at_event=0;
while(1)
{
event_message=SerialDataRead(event_message);
event_message=SerialMessageCheck(event_message,&at_event);
MessageCommand(&at_event,messageCMD);
}
}
//---------------------------Read data------------------------------------//

}
else if(Message.indexOf(M_GETMESSAGE)!=-1)
{
Message="";
*Event=S_GETMESSAGE;
delay(20);
}
else ;
return Message;
}
//----------------------The most important part!----------------------------//
void MessageCommand(int *Event,char *messageCMD) {
if(*Event==S_GETMESSAGE) // when get new SMS,execute follows
{
Serial.print("AT+CMGR=1"); //Attention,we will read the message from zone No.1
// Serial.write(0x0D);
delay(20);
while(Serial.available()<1);

What do you want to do?
Just control the motor? PWM motor control?
And you just want to control it by your phone message,right? Grey.CC
