Installation & Setup Insert the SIM card into SIM900A module. Connect the hardware as per the circuit diagram. Upload the Arduino code (gsm_motor_control.ino) to the Arduino Uno. Power up the Arduino ...

The circuit is highly-flexible so that you can use any SIM900A modem (and ofcourse any Arduino Uno board) of your choice. Carefully read the modem documentation before construction to make the task ...

This paper represents a design and implementation of a Wireless Heart rate monitor system using ARDUINO Lilypad which is enabled with the feature of sending SOS messages or calls through GSM module.
