Latar belakang, emang suka ngoprek jadi nya pengen wehh beli ini module. Cuman biasalah cari2 yang murah meriah. Cerita dapet nih module, belinya sekitar dua tahun yang lalu dari
ebay.com harganya sekitar $22, lumayan lah segitumah.
Fitur Singakat :
Support Board : Arduino UNO / MEGA / Leonardo
Support Frequency :Quad-Band 850 / 900/ 1800 / 1900 MH
Bisa sms atau nelpon .
Communication : RX SIM900, bisa gunakan D1 atau D3. Untuk TX SIM900, bisa digunakan pin D0/D2/D8/D10 pilih jumper nya
Power Button : 7
Berikut penampakan shield gsm yg udah kepasang ama arduino uno, gk perlu lagi ribet2 pasang jumper tinggal pasang ke Arduinonya

| GPRS SHIELD SIM900, TELPONAN JUGA |

Sebelum lanjut ke koding, perlu dinyalain dulu shieldnya. Berikut kode nya di taro di void setup()

//NYALAIN SHIELDNYA
pinMode(7, OUTPUT);
digitalWrite(7, LOW);
delay(4000);
digitalWrite(7, HIGH);
delay(3000);

Untuk Test komunikasi gunakan Software serial, berikut contoh kodingnya

#include <SoftwareSerial.h>
SoftwareSerial SIM900A(2, 3); // RX | TX
// Connect the SIM900A TX to Arduino pin 2 RX.
// Connect the SIM900A RX to Arduino pin 3 TX.
char c = ' ';
void setup()
{
//NYALAIN SHIELDNYA
pinMode(7, OUTPUT);
digitalWrite(7, LOW);
delay(4000);
digitalWrite(7, HIGH);
delay(3000);
// start th serial communication with the host computer
Serial.begin(9600);
while (!Serial);
Serial.println("Serial udah siap");
// start communication with the SIM900 in 9600
SIM900A.begin(9600);
Serial.println("SIM900 udah oke);
delay(1000);
Serial.println("Siap menerima perintah!");
}
void loop()
{
// Keep reading from SIM900 and send to Arduino Serial Monitor
if (SIM900A.available())
{ c = SIM900A.read();
Serial.write(c);
}
// Keep reading from Arduino Serial Monitor and send to SIM900
if (Serial.available())
{ c = Serial.read();
SIM900A.write(c);
}
}

Ketikan AT maka akan ada balasan OK, berarti sudah berhasil komunikasi dengan Shield nya.
Lanjut coba kirim sms via Software serial.

Ditas contoh koding tanpa library, ribet yaa???
Langsung aja lahhh biar gampang ngoding nya.
pertama download library nya dulu

Gampang yaa pakai library.
Selesai. dulu yaaa. moga manfaat
