GSM-based automation enables remote control and monitoring of devices and processes using SMS or calls. It automates applications like home security, industrial processes, and smart agriculture, ...

The set of operation code is placed in the void setup (). Each time when the Arduino is powered ON’s an SMS will send, as the void setup function only run once. Or Resetting the Arduino board (press ...

The code written in Arduino can communicate with the GSM modem using AT commands. AT commands are sent or received from the modem using serial communication functions provided by Arduino library.

The Arduino code takes all of the individual dialed numbers and combines them into a phone number. The sketch is set up so that after the 10th digit is read, the phone call is placed using an off ...

Code written for the Ethernet or Wifi Shield can be adapted for this shield by changing just a few lines of code. As usual for Arduino, the design of this product is fully open source, easy to use and ...

In this GSM based home automation project we are building a home automation system, where one can control the home appliances, using the simple GSM based cell phone, just by sending SMS through his ...

arduino gsm security alarm. Working of the system is very simple and self-explanatory. When input power is applied to the system, the system goes into standby mode. However, when the terminals of ...

Arduino devices have had the option of a GSM linkup for awhile, but getting that cellular link to truly strut its stuff hasn't always been easy, even for those of us who'd be inclined to program ...

This will allow the development platform to connect to the internet via GSM mobile phone networks. The module, or shield, was developed in conjunction with Telefónica’s Physical Internet Laboratory ...

If powering the GSM shield via VIN without an Arduino connected, U4 and U5 are left unpowered. Also, no caps on +3V3. Trying to power a GSM shield from a 150mA source will not work.
