Arduino + Processing + Servo control

Hello there! Im new to processing and i need some help. I have written some code that works but badly.  SImply all its meant to do is take the my keyboard input ( with proccessing) and based off that turn a servo left or right. How ever i encounter a weird problem. For the servo to turn i have to press each key on the keyboard twice.... and also when i hit 'w' there is a big delay of about 2 seconds for no reason... The processing code: import processing.serial.*; Serial myPort; void setup() {   myPort = new Serial(this, Serial.list()[4], 9600);   println(Serial.list()); } void draw() { } void keyPressed() {   switch (key) {   case 'w':     myPort.write('1');     break;   case 'p':     myPort.write('2');     break;   default:     myPort.write('0');   } } The arduino code: #include Servo myServo; int ledPin = 13; void setup(){   Serial.begin(9600);   pinMode(ledPin, OUTPUT);   myServo.attach(9);   myServo.write(0); } void loop(){   int val;     val = Serial.read() - '0';   while (Serial.available() == 0);   if (val == 1){     for (int i ; i       myServo.write(i);           }   }   if (val == 2){     for (int i ; i       myServo.write(i);     }   } }

Is it feasable for an eighth grader to build a small (4 computer) cluster running linux?

I am going into eighth grade and for my science project i want to build a computer cluster running linux. for my project  i want to test if the time it takes to process something would be cut in half, thirds and fourths when doubling , tripling and quadrupling the number of computers, or slightly less than half, thirds and fourths because of various factors slowing down processing speeds the more computers are added. Is that extremely impractical or is it possible? if so would i use software types such as pvm or mpi? Finally, are there any suggestions as to what program i should process. i need something that will stay constant ( if i did two tests with the same computer the processing time would generally stay the same) but also take long enough that slight time differences would be noticeable (1 computer takes 2 hours, 2 computers take 1 hour and 1 minute, 3 computers would take 41.5 minutes and so on and so forth).

cheap & easy way to do optical mark recognition (omr) or crude image scanning / processing?

What's a cheap & easy but reliable way to scan a crude drawing or do omr - optical mark recognition - ie read marks on paper like the forms you fill out with a #2 pencil ? I envision something like a row of 8 lights sensors spaced to match the lines on a 3x5 index card, you feed the card into guides aligning the lines with the sensors. Or get some graph paper & scissors and cut out some 3x5 cards. Perhaps this could be a crude scanner to scan simple drawngs at whatever resolution matches the spacing of the sensors (width of drawing would be limited to # of sensors, the length limited to arduino's memory/storage). You could hand-feed a 3x5 card with a drawing through it, the horizontal resolution would be the spacing of the sensors, maybe have some kind of roller to track the card being fed through so it knows to scan another line. I know there are sensors used by line-following robots, but what about a simple light sensor? Or buying a cheap camera element and hooking that up to a video input and processing the image inside arduino? Or processing input from composite video? Any thoughts?

Processing and arduino mess up after 94 lines?

I have a pair of sketches, on arduino and processing, that sends a coordinate to the arduino from a text file.  For some reason, every time it gets to the 94th line of text, it moves one axis indefinately to the side.  No matter what text file, or if I remove the 94th line altogether, or whatever, it always does the same thing. If I start on another line, it goes 94 lines, then craps out.  What's going on?  All numbers are int, if that helps, except in the processing sketch, where theres some strings, to read the text.  -edit I've changed some integers to floats, but it still craps out at exactly line 94.

A kind request: Google Science fair vote

I recently entered my Science Fair project in the Google Science Fair, an international science competition in which entrants can build, research, discover etc. anything they want to. For my entry, I researched on how prosthetic limbs can be controlled by thought alone and found that much of the mathematical analysis of the brainwave data had to be improved upon in order to make such a technology usable. Here is a brief synopsis, in case you were interested: ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- My project is, at its most general level, based upon the idea of the brain-computer interface.In this sense of the definition, anything we use to interact with machines is a brain-computer interface, including our fingers. However, amputees often face difficulties after the loss of such a vital method of interaction. Through research, I found that a current medical device, the Electroencephalograph (EEG) could be implemented as a direct brain-machine interface; in other inputs on a computer (such as a cursor) could potentially be operated by thought alone. However, I also learned that, although EEG technology has been in existence since circa 1920, it still suffers from the age-old problems of signal filtration and desired feature extraction. This means that current signal processing algorithms are not able to interpret the electrical signals exhibited by neuronal synapses very efficiently, thus making such an interface wholly impractical and inaccurate. My project sought to rectify this through the creation of custom signal processing scenarios that utilized new algorithms; specifically, the use of Linear Discriminant Analysis and Vector quantization compression/extraction methods for enhanced noise filtration and the removal of known artifacts (sources of electricity other than the brain, such as muscles). However, I decided it was not enough to run software simulations; to determine its true real-world applicability, I used a 14- channel EEG neuroheadset to gather electrical data from my own brain. I then built a prototype robotic arm with an onboard processor that would translate signals from the computer. Finally, I used the programs I created to "decipher" the incoming brainwave signals, and send corresponding messages to the robotic limb. I concluded that, by using my programs to perform the signal processing, I was able to increase the accuracy of detected brainwave patterns by about 16%. Although this may not seem like much, the brain processes hundreds of thousands of ideas simultaneously, and recognizing patterns requires a great deal of processing effort on the part of the computer. Finally, I reached an accuracy of about 91.35% using the programs I created. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Further in-depth details can be seen here: http://sites.google.com/site/eegprosthetics/home Recently, after submitting my project, I was notified that I was one of the 60 semifinalists world-wide; as part of the judging process, there is also an award called the "People's Choice Award." Essentially, the public goes online and votes once in each of the 3 age groups (13-14, 15-16, 17-18) for the project they believe is the best. I am kindly asking if you would consider voting for my project for this award; I believe this project holds many potential applications in the real world other than prosthetics alone; such technology could be effectively utilized by patients with paraplegia, paralysis, or even polio. The voting process is simple: 1. Go the Google Science Fair Voting website: http://www.google.com/events/sciencefair/projects/eeg_and_prosthetics.html (for my project) 2. Click the "vote" button in the upper right-hand corner Again, thank you for your time and consideration of my project, Anand S

What is a process that can be run on a computer cluster that displays the time taken?

For my science project this year I need a process that can be run on a computer cluster and that displays how long it took to process. The time needs to remain fairly constant yet be accurate enough to display variations in processing power. For example, let’s say that there is a computer with 4 GHz of processing power. if i were to repeat the same process multiple times then the time taken would be something like 2346765.4567865676 seconds the first time and 2346765.4567865681 the second time, so it would only slightly vary each time. if the processing power would change to 3.95 GHz then the time would change to 2346765.45679 so that variations in the processing power would be evident in the time taken. These are just examples and the values have nothing to do with my actual project but i need something to process with these characteristics. Please ask if clarification is needed.
