building interconnect circuit (developement)

The interconnect circuit is responsible for transferring data from the smartphone to the quad copter. As the smartphone sends out data through Bluetooth, a Bluetooth module is required to receive the data. This data is then processed into a signal understood by the rc module. The rc module can only decode PPM signals fed into its input pin. Therefore a processor is needed to convert the serial data received from the Bluetooth module and encode it into a PPM signal. An arduino uno board is used since it is capable to connect easily with a Bluetooth module shield. It can also encode a PPM signal using its internal timer feature.
