Hardware
1. Arduino Mega ADK
2. Wifi-shield
3. Mega Sensor shield
4. Wifi Module
Tinker-kit also comes with several micro mechanical sensors such as accelerometer, photo-resistor, among others. Each sensor can be connected to the Mega sensor shield in order to sense environmental data.
Software
Assemble the follow structure (from top to bottom)
Wifi-Module -> Wifi-shield -> Micro controller

| ### Getting Arduino ready for HTerm | |
| # 1- Set your Wifi Shield to USB (It’s a small switch on you WiFi Shield). | |
| # 2- Upload BareMinimum sketch to your Arduino ((File->Examples->Basic->BareMinimum). | |
| # 3- Open HTerm. | |
| ### Connect with following settings | |
| # Port = Port, that you arduino is connected to | |
| # Baud = 9600 | |
| # Data = 8 | |
| # Stop = 1 | |
| # Parity = None | |
| # CTS Flow control = unchecked | |
| ### Set up new Baud rate, by typing in the following into Input control box | |
| $ $$$ (Send or enter = None) | |
| $ set u b 115200 (Send or enter = CF-LF from now on) | |
| $ save | |
| $ reboot | |
| ###Connecting Arduino to WiFi | |
| # Connect as you did before, only set Baud to 115200 | |
| # Enter command mode(type $$$ (send on enter = None)) | |
| $ Set “Send or enter” to CF-LF | |
| # Type “scan” (you should now see a list of WiFi networks available) | |
| $ set wlan ssid <your wifi name> | |
| $ set wlan pass <your wifi password> | |
| $ save | |
| $ reboot | |
| # if configuration is successful then, Wifi Shield and led from Wifi module must be blinking | |
| ### Set up Arduino to communicate with Android | |
| # Enter command mode | |
| $ set ip remote 2000 | |
| $ set ip proto 1 | |
| $ comm times 1000 | |
| $ get ip | |
| $ set ip host <your android ip address> | |
| $ save | |
| $ reboot | |
Once you established communication with Android, then you are ready to start developing Arduino sketches and your Android app.
Here some code to try
