I've recently started having fun with Arduino (see www.arduino.com for details). The memory and processing speed is far below what is necessary to run the Mathematica kernel, but I wonder if an Arduino program might somehow make calls to a Mathematica kernel (running on a network-connected machine) and get results back. Has anyone done this?

Actually there is a package called ArduinoLink which I demoed at the world maker faire and at the wolfram technology conference. You use it to control the arduino with mathematica in a better way than SerialIO. The only thing is that the kernal runs on the computer so the arduino either has to be plugged into a computer or connected by a XBee. Here is a link to my demo at the world maker faire... http://www.youtube.com/watch?v=eoXADAE67ig It should be posted on the wolfram blog or other wolfram site soon. -Christopher

@ernststelzer, I am not sure what you mean by sketch, but you can include images as explained in this post. Also you can properly format and color-highlight Mathematica code in the post. Arduino site has Interfacing page with a list of progamming languages connecting to the device, among which we can find Mathematica. For pure formatting purposes are reproduce here the snipets code (I id not try it myself though). For details on using this code please see the original page. Needs["NETLink`"] InstallNET[]; NETTypeInfo["System.IO.Ports.SerialPort"] ser = NETNew["System.IO.Ports.SerialPort", "COM9"] ser@Open[] myEventFn[sender_, evt_] := (j = ser@ReadChar[]) AddEventHandler[ser@DataReceived, myEventFn] Dynamic[j] ser@Write[MakeNETObject[{254, 254}, "System.Byte[]"], 0, 2] ser@Close[]

I actually addressed this problem a while ago. If I knew how to upload a notebook or a sketch on this site I would love to share my code, since I am very much interested in this topic. The program "SerialCallResponseASCIIStelzer.ino" has to be started on the Arduino using the IDE. This program accepts various ASCII codes and responds by returning comma separated analog and pin values in a string. These are then read, converted to numbers and displayed. "A" read single values of analog inputs A0 & A1 as well as digital pins D2, D3 & D4 (simple kind of oscilloscope!!) "R" generate random values for A0 (0 ... 511), A1 (256 ... 1023), D2 (0, 1), D3 (0, 1), D4 (0, 1) (as above but for test purposes) "S" read string of 128 values of analog inputs A0 & A1 as well as digital pins D2, D3 & D4 "T" read string of 256 values of analog inputs A0 & A1 as well as digital pins D2, D3 & D4 "U" read string of 1024 values of analog inputs A0 & A1 as well as digital pins D2, D3 & D4 "Z" for test purposes Mathematica generates random single values for A0 (0 ... 511), A1 (256 ... 1023), D2 (0, 1), D3 (0, 1), D4 (0, 1) On the Mathematica side I use NETNew["System.IO.Ports.SerialPort", "COM3", 115200] to initiate and perform the communication. The most recent Arduino boards allow you to connect directly via USB but that I have not explored yet.

How do I connect Arduino to Mathematica kernel?
