Hi everyone, I'm working on a project with an UNO,
A lithium backpack http://www.liquidware.com/shop/show/MBP/Lithium+Backpack
and A gsm shield and sim  http://arduino.cc/en/Main/ArduinoGSMShield

and a series of sensors, namely the accelerometer / gyroscope - https://www.sparkfun.com/products/11486
LED ring - http://www.adafruit.com/products/1463
a capacitive touch pad (i assume made through using two pins)

and an sd card breakout board - https://www.sparkfun.com/products/11403

Basically I need:
a twist of the setup going left to make the LED lights flash and the unit to send a tweet ( on its own twitter account saying #left )

a twist of the setup going right to make the LED lights flash and the unit to send a tweet ( on its own twitter account saying #right )

if the unit is flipped upside down the LED lights flash and the unit to send a tweet ( on its own twitter account saying #flipped )

I'm willing to pay for the help in going through the setup with me etc.

Hi,

There  are some libraries which supported twitter client in arduino with Ethernet shield. But the twitter API has changed to version 1.1 which requires SSL. I dont think it possible to have code for internet connection + OAuth twitter + SSL to fit in UNO.
There seems to be a way using Application-only authentication but not sure If that also requires SSL.
There is a  ways to work around this using a middle man server receiving your tweets and posting in your account, May be in google appspot or your own server.

Hi Krishna, thanks for the reply,

as a workaround I plan to use the GSM and send texts to the twitter service.
So where it says tweet, it is sending a text to twitter which they then tweet. (this part is fine)

My main problem is getting everything else communicating on one setup and in particular the Accelerometer gyro working.

Hi Stephen,

If you are still looking for help/direction on this then i can offer you some.

Take a quick look at my website for similar projects that I have worked on for other clients WWW.EmbeddedAT.com

I have just completed a twitter feed reader that puts tweets up on a matrix display scrolling them for reading. This uses a 3rd party twitter news feed  creator that does not require SSL. This system communicated through the GSM network, BLE and WIFI.

Cheers Pete.
