Arduino Mega ADK - Fundamentals

Requirements

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

Arduino 1.0

Android SDK

HTerm (for configuring Arduino WiFi)

Eclipse ( IDE for Android application development)

Assemble the follow structure (from top to bottom)
Wifi-Module -> Wifi-shield -> Micro controller

Configure Wifi Module and Establish Android Communication

	### 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
