It comes down to voltage rating (or more aptly, derating). The Arduino GSM shield runs at 5 volts. The designers chose a 6.3V rated capacitor. While this close of a tolerance may be good enough ...

In conjunction with Arduino, Telefónica is presenting a new version of the Arduino GSM/GPRS Shield project at the Campus Party in Berlin. The project added a GPRS/GSM connection to a free ...

Today Arduino released its next official product, the GSM Shield. Arduino has paved the way for things such as cheap, easy to use development boards, all the way to DIY gaming controllers ...

Adafruit has this week made available the Arduino FONA 800 that has been designed to provide Arduino development boards with the ability to enable Arduino cellular GSM via both voice and data.

a single Arduino shield that combines GPS tracking with a GSM and GPRS transceiver. There’s also an SD card thrown in for good measure, making this one of the best tracking and data logging ...

If you fancy a challenge and have a few hours to spare, you can follow the instructions created by David Mellis, who has crafted his very own cellphone using an Arduino GSM shield. Mellis is a PhD ...

Code written for the Ethernet or Wifi Shield can be adapted for this shield by changing just a few lines of code. The Arduino GSM Shield will be available in two versions: A000043 Arduino GSM Shield ...

The device can be shipped along with Arduino’s Uno, MEGA, and Leonardo boards, and the GSM Shield itself comes with a SIM card. (You can, however, use whatever SIM card you like.) With the ...

Block Diagram The security system comprises of an Arduino Uno microcontroller and a standard SIM900A based GSM/GPRS modem. The whole system can be powered from any 12VDC/2A power supply unit/battery.

OMC has launched a fibre optic transceiver shield for Arduino Uno, designed to work with PMMA (polymer) optical cables up to 25m long, plus demonstration software ...
