I have been working around ADK and the ADK board (Arduino Mega2560). I am able to communicate over USB and talk to my board and vice-versa. Now I want to try out the same thing over Wi-Fi. I see that there are many Wi-Fi shields available. My questions are:
How do I know the shields I see online will work with ADK 2011 board?
How do I connect the shield to my board?
Do I need to flash/program my ADK board and Wi-Fi shield separately?
I am not in favor of a particular ADK board. Any suggestions for another Arduino board using which I can talk to my Android phone via USB, Wi-Fi, Bluetooth, Ble, etc. with or without shields.

i am working on a distance sensing app for android using arduino and ultrasound sensor.I found code that uses Abd for communication between android and arduino. The Abd used is for Arduino mega which has many more ports as compared to arduino Uno.I searched for Adb for uno but couldn't find it can anyone help me in finding Adb for Uno.If nothelp me with mapping of I/O ports form mega to uno.
int the adb of Mega :
DDRE 0x40 refers to Port E bit 6
DDRJ 0x08 refers to Port J bit 3
DDRJ 0x04 refers to Port J bit 2
So I need to move those IO pins to pins that Uno supports within Ports A,B,C,D and change the the DDRE & DDRJ references accordingly.
For two devices to communicate through USB one of them must act as a HOST device.
When connecting Arduino to your PC, your PC is the host.
When connecting Android to your PC, your PC is the host.
When connecting Android to the USB port of Arduino Mega, Arduino is the host.
If you (somehow) connected Android to Arduino UNO's single USB, There are no host and so they can't communicate.
You can over come this limitation by buying Arduino Uno's Host Usb Shield and connect Android to that Shield.
I wanted to test the arduino MIDI example code:
https://www.arduino.cc/en/Tutorial/Midi
I tried it with a 9V 500mA AC/DC adapter, and i used a MIDI-USB cable to get the MIDI messages to my software (Hauptwerk).
When the Arduino's USB cable was connected to the computer (the MIDI-USB cable was connected too) it worked fine, but when I tried with the adapter and plugged out Arduino's USB cable, the software didn't received the MIDI messages.
To the serial communication I used the TX-pin like in the tutorial.
I am using an arduino board and I have connected a Zigbee shield to the board. A switch is connected to one of the gpios available with the arduino board.
The problem is when I press the switch at a very high frequency the arduino board is resetting itself. When any other zigbee is powered on then the board is not rebooting. Please suggest some solution for this problem.
I have an arduino mega ADK, with usb port, and an arduino uno.
- On the arduino uno, I put a xBee shield with the wifly module for connect to the internet.
- On the arduino mega ADK, I put the TinkerKit! shield.
I need to use both : xBee shield and TinkerKit!. and the single way i found, is to connect the arduino uno to the arduino mega ADK by USB wire (the wire is the one I use to connect an arduino to my computer).
Do you think it could work ? If yes, How can I get what is writting on the outpu of the arduino uno ? If no, is there an other way to do what I need ?
yes, it can be done, but is is way more easier to use directly the Hardware/Software Serial. Even if you get iw work, it will be a serial simulation over usb..
So using USB is just a layer of complexity that can break, and nothing more.
is it possible to see data of android device when is it in accessory mode??
in my opinion what we need
1. USB hub
2. android phone(which work with accessory mode)
3. Arduino Mega ADk
4. USB cables first for android device and second for USB hub to PC
Connection
1.connect hub with Arduino ADK (where we have connect android device)
2.connect android device with hub(Via usb cable)
3.connect hub with PC(via usb cable)
all things i did but my PC is not detected Android device
any kind of suggestion will be appreciated
Thanks in advance
Your Android device will not be detected when it is connected to a Mega ADK board. The reason is that both PC and Mega ADK will act as USB Host and so only one can be connected at a time.
If you want to debug and want to see the output of logcat, then you can use ADB Wireless app.
