Sim900 GSM Module Interfacing to Arduino

This part of instructable explains GSM module interfacing to arduino.

Now a days GSM is used in all the projects for wireless data transmission or alerting and messaging system.

Step 1: Interfacing SIM900 to Arduino

This part of instructable explains GSM module interfacing to arduino. Now a days GSM is used in all the projects for wireless data transmission or alerting or messaging system.

HardWare Required :

1) Arduino Uno Board

2) SIM900 GSM module

3) Connecting Wires

4) Bread Board

Step 2: Hardware Connections

1) GSM Module is powered using 12Volts DC adapter.

2) Arduino is powered using USB cable / Adapter.

3) 2nd pin of Arduino is connected to TX pin in GSM module.

4) 3rd Pin of Arduino is connected to RX pin of GSM Module.

5) Arduino GND is connected to GSM GND.

Step 3: Importing SIM900 Library to Arduino IDE

Please download the GSM Shield library from the below link and add to the arduino IDE.

http://www.gsmlib.org/download.html

As shown in the above screen shot please browse the ZIP file and include the library after including the library, Close the Arduino IDE and open it again then you will find the library included.

Open Arduino IDE.

Go to FILE --- > Examples --- > GSM Shields -- > You will have some basic programs open them and upload them to the Arduino.

Now you can use some basic programs and practice programming and use for your project .

All the best for your Project .

Thanks,
