This project can be developed with Arduino or Intel Galileo. It is also compatible with Raspberry Pi using the Raspberry Pi to Arduino shields connection bridge.
For further information about the GPRS/GSM QUADBAND MODULE (SIM900) Shield, consult the main tutorial.
Step 1: Connection Go to index
Connect the GPRS antenna to the shield and then, connect the shield to Arduino or to Raspberry Pi connection bridge. Connect the resistor and the buzzer in the breadboard as you can see in the next diagram.
Connect two wires, red and black, to the two long rows on the side of the breadboard to provide access to the VCC supply (5V in Arduino and 3.3V in Raspberry Pi) and ground. Then, connect digital pin 9 to one leg of the resistor. That other leg of the resistor is connected to the negative of the buzzer.Finally, connect positive terminal, marked with a “+”, to VCC.
