3  Using Arduino / Storage / Re: Arduino + official ethernet shield + SD -> all working together. on: July 02, 2012, 03:31:27 pm
I just spent a painful 20 hours banging on an arduino ethernet shield with an SD card trying to get them to work together.  This thread, ladyada's tutorial - all resulting in arduino crashing when switching between ethernet and SD - nothing worked.

Reason: I was using the Arduino IDE 1.0.1 - everything works when I went back to 1.0

Symptoms - garbage spat out into serial, setup() restarting, not being able to open the files, etc.

I want my weekend back  smiley-eek-blue
4  Community / Exhibition / Gallery / nimbits 3.3.1 - new search engine, javascript capabilites on: February 06, 2012, 01:05:08 pm
Hi Everyone,

nimbits 3.3.1 came out today. This version includes sample code to embed live, interactive, streaming charts of your arduino sensors into web pages using Javascript. We're doing a lot with XMPP M2M communication - so arduino projects can chat with each other using the same protocols as jabber and google talk.

Please remember, since Nimbits allows you to power your robotics projects with Google's infrastructure, and connect them to all of the expert knowledge in Wolfram Alpha and then connects all of these projects together - please include me on the "do not kill" list should any of your projects become self aware  smiley-lol

check it out: let me know if I can answer any questions.
5  Community / Exhibition / Gallery / nimbits 3.3 - connecting arduino to wolfram alpha and XMPP on: December 08, 2011, 11:18:38 am
Hi Everyone, I wanted to let you guys know I released nimbits 3.3 this week.  Nimbits is a "cloud computing" based data logging service i designed for recording sensor data.  The new version let's you automatically process incoming data against the wolframalpha computational knowledge engine (Appel's SIRI uses WA in part for AI). This means you can post data from an Arduino and have that data processed by WA and have the response relayed to another device or used to make intelligent decisions.  I think powering an Arduino project that uses all of the knowledge in WA and the processing power of Google App Engine is pretty cool!

Nimbits also has the ability now to connect devices to XMPP, the same way google talk and jabber communicate instant messages. So devices can appear "online" just like someone using IM and they can chat with each other using IM.

I also documented how to build a Nimbits Server internally on your own hardware instead of just Google App Engine, and/or Amazon EC2. Let me know if you have any questions.

Thanks for the reply KE7GKP,

I didn't realize that the playground was a wiki I could edit - i added my project under the Ethernet section. I welcome everyone's feedback.

Hi Dan looks good,

I was just passing by and noticed your post. If you want to have some fun with this, I have an open source project going where you could add a few lines of code to this and post your values onto the nimbits data logger system ( and your temps can be relayed onto twitter, facebook, email alerts etc.

Anyway I just noticed that your arduino code is similar enough to what I posted under the arduino example on and since it's connected to an ethernet shield it should be pretty easy. Just thought i'd mention it.

Hi Spencer,

I already put a ton of effort into writing this web tier for arduino data and it integrates into Google Charts, the source code for loading google charts etc is all on the web site. Hopefully it helps you guys out and saves you some $.  If you don't have an Ethernet Shield, I have a .net and java SDK that makes it really easy to pull data from arduinos attached to a USB and push the data up to Nimbits Data Points on the web or to an instance of Nimbits Server running locally. Take a look at the SDK links on

One of my users just wrote a cool Google Gadget that lets you see your data on a google site or igoogle:

Hope this helps.

Hi Rob,

This is a really cool project. I wanted to share with you some arduino code that I posted that lets you relay data like this to google app engine.  I have a whole open source project going that you could use to get this data onto spreadsheets, android etc.

Here is the arduino

Here is the web site:

A lot of guys i know are using it to automate greenhouses

Hi Guys,

I try to keep this forum updated with the released of my open source temporal database system: Nimbits. I just put out v3.1 - this version allows you to "friend" each other either on the instance i have running on or download your own and connect that way. When you connect to each other you can see your sensor feed data and share charts etc.

It's free and open source, feel free to check it out and let me know if you have any questions:

Hi Guys,

I spent 10 years working in the process control / automation industry and about 6 years ago started an open source data historian server project. It's evolved quite a bit and currently has a relatively strong arduino user following.  I released a windows and java SDK and arduino source code for posting sensor data onto the historian, which now runs on google app engine.

I was wondering what it would take to get a link on the site under the getting started section.  I think since the software is open source, it has a close philosophy with arduino. It's free and a good way to learn about "internet of things" concepts.  I host an instance of the server on, which also has a mechanism where users can "friend" each other to see each other's data points.

I'd appriciate any guidence and your thoughts on how the arduino comunity can use what is essentially my life's work  smiley-roll-sweat

This software is called Nimbits and is @

13  Community / Products and Services / Nimbits Data Logger 3.0.10 on: March 15, 2011, 07:36:47 am
Hi Guys,

Just an update to let you know that last weekend we update Nimbits to version 3.0.10. You can download a new version of the java and .net SDK that lets you record arduino data to the cloud.

Nimbits is a free, open source cloud computing based data logger that Arduino based devices can use to record data into online data points on the cloud. It provides alerts, calculations, storage, relay etc.

You can use the public server on or download and install your own instance. The new version has some cool instant messenger features where you can chat with your data over IM.

Check it out, and let me know if you have any questions. I posted a tutorial on how to post data using an ethernet shield directly out to the cloud without needing a middle tier to relay the data here on my blog:

Hi Andy,

I'm the owner/inventory of nimbits data logger. I usually respond to user support request in 24 hours or so. Please let me know if I can help you out.

I just re-did the web site with a new wiki on

Also, I posted this tutorial  which shows how to post data directly from Arduino to the Nimbits Cloud from an ethernet shield without the need for a middle tier.

15  Forum 2005-2010 (read only) / Syntax & Programs / Re: map analogRead to voltage value on: October 26, 2010, 11:21:04 am
The map function uses long, so you won't get a float back. this function will return the supply voltage 0.0 - 5.0 based on the analog reading of 0-1023

void loop()
  int raw = analogRead(analoginput);
  float val = fmap(raw, 0, 1023, 0.0, 5.0);
  Serial.println(val); //voltage

float fmap(float x, float in_min, float in_max, float out_min, float out_max)
  return (x - in_min) * (out_max - out_min) / (in_max - in_min) + out_min;
