When getting started with Arduino, it is good to have a shield with a lot of integrated components to get used to how to interact with the different sensors and ... (updated a bit by me). Looking up ...

We peeked at the schematic and the shield is more for letting the Arduino control the radio by changing the oscillator frequency rather than performing the SDR functions.

The base shield contains a WCDMA and HSPA compatible 3G modem as well as a GPS receiver. The modem can be used with an Arduino, or plugged directly into a computer via USB, allowing it to be used ...

The last few chapters start bringing in more complex notions for collecting and sharing data. First we learn the basics of using the Arduino Ethernet shield to connect your Arduino to a network ...
