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.

Of course, we’ve seen GSM and cell phone shields for Arduino before. Difficult to imagine sticking those in a dog collar, though, unless you have a fairly large dog. If you are a fan of 1960’s ...

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 ...

Be careful with those Arduino GSM cards. As [James] reports, they may turn into fire starters. One person has reported a small explosion and fire already on the Arduino forums. Now before we go ...

For this project, you will need an Arduino Pro Mini, 1 GSM module with battery and antenna, four jump wires, and one breadboard. Start by disconnecting everything from its power source and then ...

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.

Arduino has two new boards out which deliver connectivity – the Arduino MKR WAN 1300 (LoRa) and the Arduino MKR GSM 1400. The Arduino MKR WAN 1300 delivers LoRa low-power WAN connectivity, and the ...

The development kits consist of an Arduino or a Cinterion board with a GSM chip, a SIM card, and access to the M2M Developer Platform. The launch will coincide with the relaunch of the M2M Developer ...
