bonjour tous j'ai acheter une carte ethernet mais j'ai des questions sur les broche visiblement les broche 13 12 11 sont utiliser pour un bus spi mais je peut les utiliser en sortie ou pas ? la broche 10 sert activer le module donc celle la je la met en etat haut tout le temp ? et la broche 4 servirait pour activer la sd mais moi je compt pas m'en servire je peut utiliser la broche 4 en sortie du coup ? pour eviter tout probleme si je sépare mon ethernet de ma uno et que - je racorde les 6 fils du bus iscp - l' alim 5v - je met la broche 10 du ethernet sur le +5v sa fonctionnerai ou pas ? si je fait un include ethernet il va pas essayer de se reserver des broches ? mon arduino toute ces broche de prise donc sa devient compliquer merci vous quote from: windaube21 on jun 25, 2013, 08:31 pm j'ai acheter une carte ethernet mais j'ai des questions sur les broche c'est celle ci ? http://arduino.cc/en/main/arduinoethernetshield ...

i have project involving relay, pir sensor, , ac fan. works intended ugly, ugly, 2 wall warts, 1 supplying arduino, relay, , wire fan, coming power strip. single wire ac outlet box more elegant.  assume arduino , relay can't supplied single wart via transistor, or in case, tip120?  mains power accessed single terminal inside project box 2 warts? ignorant question, coming wall gives me willies! you have not said voltages , currents using. i can guess relay requires more 5 v and/or more 30 ma.  perhaps should different relay. if relay used 5v , <30 ma can run directly arduino pin without separate power supply or transistor driver.  if uses 5v , >30 ma (up 400 ma) can drive arduino transistor.

hypothetical scenario, illustrate design parameters: ------ say wanted make steak cooking appliance. @ point in cooking process, want measure how steak cooked. way want implement steak cooking state check prodding steak (probably form of linear actuator), , measuring "hardness" or "squishiness" of steak. "harder" or "firmer" steak, more "well done" or cooked is. "squishier" is, more rare or raw is. now linear actuator can tell me how far actuator has moved via normal feedback mechanisms. i not want sensor @ end of linear actuator between steak , actuator, fat, heat, food scraps, etc, can impact sensor , render unhygenic, etc. so "squishiness" sensor needs implemented other way / location. ------ as said, hypothetical scenario, purely setting parameters of design. assuming linear actuator not stall, , has limit switch or similar prevent prodding far steak, , assuming knows surface of steak is. i guessing cal...

hi, have been using ubuntu while now, , since have upgraded few times. since last upgrade little buggy, though when karmic comes out, i'm gonna fresh install. plan do, , here need confirm i'll doing ok, go in livecd or usb, format ubuntu partition, , install karmic on that. that's how guess os in uninstalled, please tell me if i'm wrong. can't figure out if grub take care of itself, or if i'll need it. dual booting vista , jaunty. 1 other thing, should format partition ext4, or should stik ext3? you don't need partitions beforehand. run karmic installer, , can format partitions in it. grub should automatically recognize xp installation, did first time installed. ext3 vs. ext4, can't anything. stick ext3, since don't see reason move ext4.

hallo alle zusammen, ich benötige mal wieder etwas hilfe von euch ! und zwar bin ich durch ein thema http://forum.arduino.cc/index.php?topic=173309.0 auf den gedanken gekommen, ob ich nicht auch meinen taschenrechner mit dem arduino verbinden könnte. und zwar handelt es sich um den ti-84 plus. nach ein wenig suchen bin ich auch schon auf eine lösung gestoßen http://www.youtube.com/watch?v=nepnmtsl09q , nur wurde dort das programm nicht in c/c++ geschrieben und da ich mich mit assembler (wenn ich mich nicht täusche handelt es sich darum) noch nicht wirklich auskenne, habe ich da meine probleme die wichtigen dinge da raus zu „filtern". von daher meine frage euch: hat hier jemand eine idee bzw. hat es  schon mal jemand umgesetzt, dass der arduino mit dem taschenrechner über den serial link port kommunizieren kann ?! weil ich jetzt nicht einfach drauf los basteln/programmieren, denn der taschenrechner ist ja nicht allzu günstig. deswegen wären tipps echt super. dabei habe ic...

tiny core 2 ready (enough) human consumption.  it's available in usual place... http://code.google.com/p/arduino-tiny/downloads/list  on source tab, it's under "core2" repository. there support t861, t13, t85, , t84 processors not complete.  expect find bugs , things missing. if have request, please post here.  more requests = higher priority. if have question, please post here. if find bug, please post here. there 2 goals core: smaller , configurable.  to accomplish first goal, there 2 versions every arduino function.  an inline version , normal version.  the inline version used when key parameters constants.  the normal version used otherwise.   pinmode is perfect example.  if 2 parameters constants, pinmode reduces 1 or 2 machine instructions.  if pin is constant, pinmode typically reduces fewer 6 machine instructions. the "variants" feature used configure core.  a file named[font=cour...

hello, i have purchased several i2c color sensor - grove seeedstudio. http://www.seeedstudio.com/depot/grove-i2c-color-sensor-p-854.html?cpath=25_27 i connect more devices same i2c slot. use i2c hub seeed studio: http://www.seeedstudio.com/depot/grove-i2c-hub-p-851.html?cpath=98_16 if connect several sensors , try i2c scanner sketch, receive 1 address. can connect more 1 of sensors arduino? how can change i2c address of sensor? hardcoded in sensor? as product query, consult seeedstudio forum http://www.seeedstudio.com/forum/ Arduino Forum > Using Arduino > Project Guidance > Connect more i2c devices to an Arduino arduino

anyone know of code set rtc (ds1307) using ntp via enc28j60 chip preferable using ethercard library?   finding combination out there not 3 of them.  just getting arduino easy.   can work little bit of code @ point not complex stuff.   learning examples @ stage.  using unor3 if matters. why want ? why not use ntp , adjust time setting there ? do need sub-second accuracy ? if not run ntp update every minute or , good. craig Arduino Forum > Using Arduino > Networking, Protocols, and Devices (Moderator: fabioc84) > Set RTC with NTP using ENC28J60? arduino

comprei um arduino uno, usei ele de boa para o primeiro programa, mas não sei o que aconteceu que ele parou de conectar no pc, eu ligo ele na usb ele só acende nao faz mas nada o pc n da nem sinal dele, já teste outro atmega328 e continua igual, me ajudem ae não sei oq pode ser, agr só da pra usar ele com programação que deixei, estava usando um modulo bluetooth o módulo bluetooth ainda está ligado ao arduino?

olá, peço desculpa pela pergunta mas existe alguma forma de converter uma variável char em string? eu tenho um array com vários carateres e queria usar alguns de umas posições para os converter de hex para dec o que queria fazer era algo como isto: temphex=hextodec(bufin[9]+bufin[10]); usar função hextodec para converter uma string (que tem código hexadecimal) num número dec. o meu problema:   error: invalid conversion 'unsigned int' 'const char*' podem ajudar-me juntar os dois carateres '5' + 'a' numa única string sem que dê o erro qdo os tento depois converter, o meu objectivo é ter como resultado '90' (o código hextodec está correcto o problema é mesmo o tipo de variável que estou usar e juntar os caracteres). exemplo que estou fazer: code: [select]   char bufin[12];   string temphex;   void setup(){ bufin[9]= '5'; bufin[10]='a'; [b]temphex=hextodec(bufin[9]+bufin[10]);[/b] } void ...
