Arduino: send SMS - how it works

In this practical tip, we will show you how you can easily send an SMS with your Arduino.

Arduino: send SMS

To send an SMS with your Arduino, you need a GSM module, which you have to set up beforehand.

• First start the Arduino IDE and click on the "File" tab.
• Then move the mouse to "Examples" and navigate to "Examples from own libraries".
• Navigate here to "GSMSHIELD" and click on "GSM_GPRSLibrary_SMS".
• Scroll down to line 40 and remove the two slashes at the beginning of lines 40 and 41.
• Enter your own number and an SMS in the command in line 40: »if (sms.SendSMS (" + 49123456789 ", " Hallo CHIP! "))«
• Finally upload the code to the Arduino and put the GSM module into operation as described above.
