hi all, i tried find clue on how solve problem below seems stuck. appreciate help. i'll make story simpler. trying operate valve driven small stepper. @ closed position valve hits limit switch. using switch open or close valve. easydrive board used driving stepper.  i implement following logic: in case open command received motor should turn 8000 steps 1 side. in case close command received motor should turn 8000 steps other side. then, in case limit switch not activated turn additional 1000 steps. use accelstepper library because plan operate more 1 valve in parallel. anyhow code without limit switch seems work fine, see below: code: [select] void loop ( )  {  cmdvent = digitalread (cmdpinvent); //read vent valve command open (low) or close (high)   if (ventvalve1.distancetogo ( ) == 0) {    //check open command    if ( cmdvent == low && cmdventold == high ) {      ventvalve1.move (8000);      cmdventold = cmdvent;    }    //check close command    if ( c

hey guys, i'm finish master in fine arts, made serious mistake. i have arduino controlling small motor. motor supposed run 1min, stop 3min or, 4 min. the mistake did, overwrote working code old one. problem old code is, although motor seems run fine, know there chance, code stop working after random amount of time (it did year ago , had programmer @ school on it. found little mistake , corrected it, but, said, accidentely deleted corrected version). so, i'm asking guys huge favour... please on code , tell me, couse error? have done in 3 days , object running in musuem, can't can't can't stop working... a thousand already. -maikell here's code: code: [select] #define motor 9 void setpwmfrequency(int pin, int divisor) {   byte mode;   if(pin == 5 || pin == 6 || pin == 9 || pin == 10) {     switch(divisor) {       case 1: mode = 0x01; break;       case 8: mode = 0x02; break;       case 64: mode = 0x03; break;       case 256: mode = 0x04; break;       case

hi everyone, newcomer have few questions in little project have been working on. i have created simple code controls servo 2 different buttons. when pressed 1 turn servo left , 1 right. problem code works little wrong. servo turns when button pressed down , want make movement once button pressed. if press button real quick, servo goes position , comes back. i hope don't sound confusing here video of setup, , code https://www.youtube.com/watch?v=g4btwh3sod0&feature=youtu.be code: [select] #include <servo.h> servo myservo; int button7=0; int button6=0; int pos=90; void setup() { pinmode(7, input); pinmode(6, input); myservo.attach(9); } void loop() { button7=digitalread(7); button6=digitalread(6); myservo.write(pos); delay(5); pos=constrain(pos,0,180); if(button7==1 && button6==0) { pos = 0; } if(button7==0 && button6==0) { pos = 90; } if(button7==0 && button6==1) { pos = 180; } } 1) please edit posting use code tags,

hello, i have decided build simple clock school project. specifically, plan build lite brite clock. if haven't seen it can seen here;   http://www.instructables.com/id/lite-brite-led-clock/    so, can see, user has made nice write of construction, upon further inspection see there no way set time other reprograming arduino. so, question is, me add code set time 2 momentary switches or similar? below attached "wiring diagram" the author says change time using line of code 6 lines down says "settime" have rest of code, assume need. if you've got more questions let me know. , help code: [select] #include <time.h> int column[]={0,1,2,3,4,5,6,7,8,9,10,11}; int row[] = {14,15,16,17,18}; void setup() {  settime(9,27,0,27,7,2012); quote so, question is, me add code set time 2 momentary switches or similar? you need more two. need 2 move left or right through series of values - month, day, year, hour, minute, , second - , 2 incre

estou usando um código de exemplo que vem junto com biblioteca pra usar o motor de passo. eu tenho em mãos pra uso o shield l293d mais uma placa arduino uno e 2 motores de passo no shield, identifiquei os fios e tudo mais, parte fisica está pronta agora com esse código eu consegui fazer 1 motor rodar por vez e não consigo fazer os 2 motores de passo rodarem juntos, alguém poderia me ajudar. o código que estou usando de exemplo é este : code: [select] // adafruit motor shield library // copyright adafruit industries llc, 2009 // code public domain, enjoy! #include <afmotor.h> // connect stepper motor 48 steps per revolution (7.5 degree) // motor port #2 (m3 , m4) af_stepper motor1(48, 1); af_stepper motor2(48, 2); void setup() {   serial.begin(9600);           // set serial library @ 9600 bps   serial.println("stepper test!");   motor1.setspeed(30);  // 10 rpm      motor2.setspeed(30);  // 10 rpm    } void loop() {   serial.println("single coil steps&

hello all, i new , have question. i have bought 2 arduino ethernet shields. http://arduino.cc/en/main/arduinoethernetshield my goal have 2 ethernet shields 1 input, 1 output , connect input lets wall jack , pass though second shield connect client. through process sniffing traffic i have code written sniffing portion of can not pass data when connect 2 arduino ethernet shields. able plug 1 shield wall port (input) , use other shield pass traffic (output) client. i hoping going plug , play not. thoughts or suggestions on how these 2 ethernet shields play , allow traffic pass through 2 of them appreciated. i open other ideas , thoughts well. find old-fashioned ethernet hub (not switch).  connect sniffer , device being sniffed hub , sniffer see traffic going , device.

i want count events  following buckets. this objects falling through chute. this input changes 500ms can never change there can significant data organize or none. last 60 minutes last 24 hours last 48 hours so, realize may need timestamp events, want rolling, real time update. i'd without rtc, using millis() does have experience simplifying trying here? how many events expect in 48 hour window? surmise, have timestamp of them. in simple case, means storing unsigned long each event @ cost of 4 bytes apiece. you push data sd card or reprocessing on timestamps & other trickery fewer 4 bytes of ram per event, max number of events you're going guide towards arduino you'll need. alternatively, offload data storage pc , let tell arduino counts per bucket are.

hello i have created movie on cd-rom has button users can install software cd drive. movie first changes resolution 800 x 600 resets when exited program. there number of issues i'm unsure about, being bit of novice. firstly, wiser have installation shut down when user clicks on button install additional software? secondly, should first reset screen resolution original? any other issues should know about? currently, here have coded button on mouseup me barunprogram( moviepath & "xtrasoftware\program.exe", "normal", true ) end anybody sort of thing on regular basis? any appreciated. i'm not of lingo expert please don't make technical!!! thanks andy hi andy, the best way tell if need change user's resolution when you run installer test. guess switching user's resolution run installer odd. if don't need quit projector run installer, probably don't want change user's resolution. -- rob _______ rob dillon adobe com

hi, i've installed kubuntu 9.04 on sony vaio vgn-c2z notebook geforce go 7400 gpu few days ago after having tried while live-os. when using live-os automatically configured resolution correctly, when tried install it didn't start x-server, had use alternative graphics mode. runs , starts x-server long use vesa driver, try use nv, nouveau or proprietary nvidia driver, x-server won't start telling no screen found. on other hand, long use vesa can use 800*600 oder 1024*768 on display natively supporting 1280*800... tried lot of different things now, nothing worked. think reason problem misconfiguration of monitor, log says "display found cannot used". hoping karmic propably better, did update 9.10 beta today, still same problem occurs. hope has idea, posted problem in 2 big german ubuntu communities without finding solution it. in advance! xorg.0.log code: x.org x server 1.6.3 release date: 2009-7-31 x protocol version
