Simduino - Uno + SIM808 GSM & GPS + Antennas

When SIM808 “melts into” the Arduino, what wonderful things will happen? Look at the latest Elecrow SIMduino. This small board combines Arduino uno and sim808 module. It will save more cost and space for your project and easier to build other modules. It does not only need to be powered by a DC power supply, it has been designed with a battery interface for it, you can also use a 3.7V lithium battery to power it. The SIM808 module can communicate with the Arduino via software serial port(PD7 and PD8) and hardware serial port(PD0 and PD1).

Example - Sending A SMS




#include <SoftwareSerial.h>

SoftwareSerial mySerial(7, 8);

void setup()
{
mySerial.begin(19200);  //Default serial port setting for the GPRS modem is 19200bps 8-N-1
mySerial.print("\r");
delay(1000);                    //Wait for a second while the modem sends an "OK"
mySerial.print("AT+CMGF=1\r");    //Because we want to send the SMS in text mode
delay(1000);

//mySerial.print("AT+CSCA=\"+919032055002\"\r");  //Setting for the SMS Message center number,  
//delay(1000);                                  //uncomment only if required and replace with
//the message center number obtained from
//your GSM service provider.
//Note that when specifying a string of characters
// " is entered as \"

mySerial.print("AT+CMGS=\"+9184460xxxx\"\r");    //Start accepting the text for the message
//to be sent to the number specified.
//Replace this number with the target mobile number.
delay(1000);
mySerial.print("Hello World\r");   //The text for the message
delay(1000);
mySerial.write(0x1A);  //Equivalent to sending Ctrl+Z 
}

void loop()
{
//We just want to send the SMS only once, so there is nothing in this loop.
//If we put the code for SMS here, it will be sent again and again and cost us a lot.
}
