Hi there! I just wanted to ask if how can I connect the SIM800L GSM module to the arduino and programming it. Can I ask as simple as it is because I'm still 13 
You will find connection diagram & example software here http://www.seeedstudio.com/wiki/LoNet_-_GSM/GPRS_Breakout
External power 4V+- @2A connects directly to phone shield. Common GND for arduino & shield.
The examples often use software serial. Your wireing must match software settings Rx->Tx ( Tx->Rx)
When SIMcard is inserted.. and you get a connection : The blinking pattern tells you.
