you have to follow the link to the website and read through the other links that will lead you to the qr code and download link for the amarino bundle application

I found no QR Code on the site you referenced. I am new to Droids having just purchased a DroidX. I have not connected to my Pc and was hoping for an easier way to install. As you8 would expect, I am sure not an Android ptogrammer!

[...] about Sensor Graph helped me a lot to write the tutorial. You can see the original link here: http://bygriz.com/blog/sensor-graph/ . In this tutorial, I will basically revise the instructions given on bygriz.com and make it more [...]

I made the same procedure but i can’t see graph…where is the problem?

——–
check your Arduino serial monitor and check to make sure the values are being communicated to the phone, or you can check Amarino’s monitor that is included with the app.

does it have to be the gold smirf, or will the silver smirf do?

——–
both should work, I believe silver has a shorter range.

Hey that s great! Could you post some more details about the wiring?
Thanks!

- sure what part of the wiring would you like to see?

Hey man. Great tutorial. I’m somewhat new to this game, but went out and bought a BlueSmirf Silver from Sparkfun. Shorter range, but will work for what I want. My only goal, is to do what you have done above. (communicate via Android to my Arduino).

So, please forgive me if I am asking fairly common knowledge questions.

Anyway – My hookup is as follows:

RX(0) on ATMega328 to TX on BlueSmirf
TX(1) on ATMega328 to RX on BlueSmirf
5V on ATM to VCC on Smirf
GND to GND

Trimpot:
Far Left – to Gnd
Far Right – to 5V
Center – to Pin 5 (as mentioned in the Tutorial)

I am able to pair my phone to the device just fine. Both applications run correctly. I built the fresh SensorGraph app from Eclipse (I am an Android Developer so I had it all installed).

I am able to install the code from Arduino 0022 (by using your method of removing the TX & RX beforehand).

When I launch SensorGraph, it pairs and finds the device just fine.. But nothing displays on the screen except “Hello World, SensorGraph!”. I am running a Moto Droid 2. Running Android 2.2.

Im afraid I just dont know what I am missing. Can you spot me a minute to help? Let me know if there is any information that I may have left out, that may be helpful.

Thank you very much for your time.

if you are not seeing the graph at all check your wiring again and make sure it is correct.

Thanks for this nice tutorial. I put it on the Amarino website if you don’t mind.
