use folloing library file for ADC communication, 

 

 

#include<avr/io.h>

#include<adc_lib.h>

 

 

 

#define ADC_VREF_TYPE 0x00

 

// Read the AD conversion result

unsigned int read_adc(unsigned char adc_input)

{

ADMUX=adc_input|ADC_VREF_TYPE;

// Start the AD conversion

ADCSRA|=0x40;

// Wait for the AD conversion to complete

while ((ADCSRA & 0x10)==0);

ADCSRA|=0x10;

return ADCW;

}

 

// header file//

#include<avr/io.h>

 

unsigned int read_adc(unsigned char);

void ADCinit();

 

 

 

 

void ADCinit()

{

ADMUX=ADC_VREF_TYPE;

ADCSRA=0x85;

}

yes u can use TTL based GSM modem, conncnnct microcontroller  pin rx to GSM tx and microcontroller pin TX to GSM rx. and write the code for atmega8 and write the message in the code and  you can eaisly send the message to any mobile no.

use any kind of programmer like usbtiny, USB asp .and use any sofware for transfering hex file in microcontroller like sinaprog, extreme burner..
