The new shield designed for Arduino and Raspberry Pi integrates the SIM908 module which counts with both GPRS and GPS technologies what allows to easily perform realtime tracking applications. The idea is simple: read the GPS coordinates (longitude and latitude) and send them by using a HTTP request to a web server. Then use a

Method 1 The simplest way to generate a frequency is to apply a voltage to a crystal, the piezo-electric effect will take over and the crystal with resonant at a particular frequency. However, as this was going to be a multiband, multimode transceiver; crystals could not really be used. The range over which a well
