    2525You only need to connect the radio chip to the Arduino. Follow the instructions in ConnectingRadioModule.

    2827As an option you also can connect inclusion button & indicating leds. Pin to be used by button is defined inside ArduinoGateway sketch as #define INCLUSION_MODE_PIN 3. Actually it is hard to redefine it because sketch is using the particular interrupt handler. Connect button between +5V and digital pin 3 with a 10k pull down resistor to GND (see image).

    3029There are 3 led types supported - RX/TX/Error. Use them to have a visual feedback during radio activity. Radial 3mm green/yellow/red leds could be a good choice. Your should use 3 resistors 270R-510R. Each led is connected by anode to +5V pin and cathode is connected through a resistor to a digital pins 6/5/4 respectively for RX/TX/Error. Pins can be re-configured inside ArduinoGateway sketch at this line:

    4445This is the stuff you need to purchase to build the ArduinoGateway. Note that I've provided links to the things I bought during the development. You might find it cheaper somewhere else. Also note that you might need to buy more than 1 product to get the price specified.
