Hi all, today im going to tell about making a simple mobile phone from your arduino uno!

Step 1: Equipment

- Arduino UNO

- GPRS shield with sim900 (i bought it here Amperka)

- AUX cable, microphone and speaker (i used JBL Go)

Step 2: Warning!

GPRS shield isn't working correctly when using internal Arduino Uno power supply, so you need to use external power to arduino. See my adapter on photo

Step 3: Check

If you all do correctly, after connecting external power you can see blinking ledS on gprs shield, it means that gprs board correctly connected to your mobile operator. See pic

Step 4: Sketch

After you complete all hardware steps you need to load simple firmware to your Arduino uno:


Step 5: AT Commands

Interaction with sim900 module occurs via AT-commands.

To send AT command you can use SSCOM3.2 software.

Some basic commands can be founded here

For example to make call you need to send command ATD[Number]. See pic.

Thanks!
