hallo leute! mein name ist johannes und ich habe bisher nur als mitleser von euren tollen forum provozieren. vielen dank schon mal. doch für mein momentanes problem hab ich noch keine lösung gefunden. ich bekomme von einem steuergerät über acht ausgänge zwei binärzahlen ausgegeben. diese ich mit 2x4 analogen io auslesen. die elektrische vorschaltung habe ich bereits getestet und die auswertung klappt problemlos. jetzt fehlt es mir aber einer idee zu einem programmcode, mit dem ich vier io's auslesen kann, der mir eine variable mit einer dezimalzahl ausgibt. sprich 1-0-0-1 als 09 ausgibt. später ich die beiden dezimalzahlen/-variablen dann nutzen um unterprogramme auszuführen, wenn z.b. variable x den wert 03 hat und y = 09. der code soll dann etwa sekündlich prüfen, ob sich der binärcode vom externen steuergerät geändert hat. wenn ja, soll eine andere funktion durchgeführt werden. ich das aber nicht mit einer if else lösen, da verschieden kombination von variablen gleiche

buon giorno ragazzi mi é venuta un'idea malsana , ho un circuito di temporizzazzione un po complesso, il circuito funziona tutto dovere, molto spesso devo  settare vari tempi in quanto il circuito deve funzionare in piena autonomia e visto che minimo una volta al giorno viene spento la notte e riacceso la mattina le impostazioni delle variabili dei tempi le cambio direttamente valori di default del listato quando inizializzo le variabili. il problema nasce quando mando qualche altra persona cambiare settaggi. avendo loro una conoscenza pari 0 nella programmazione avevo pensato e quindi vi chiedo é possibile tramite la seriale del  software programmatore di arduino o altro software simile, tramite apposita interfaccia,  cambiare valori della variabili inizializza in modo che ad ogni avvio mi rimangono gli stessi valori? se non sia possibile esiste altra tecnica per memorizzare esternamente, tramite sd o altro, questi valori e al riavvio richiamare quest'ultimi? grazie

hallo, ich habe vor eine 3-kanal lichtorgel mit led-strips und einem arduino uno zu bauen. angefangen habe ich mit einem tiefpass(hochpass und bandpass kommen natürlich auch noch dazu) durch das mein audiosignal läuft, danach noch durch eine diode zum gleichrichten und dann auf einen analogen eingang vom arduino. vom pin 3 des arduino gehe ich zu einem transistor der dann die 1. farbe des led-strips steuert. da ich kein experte im gebiet des arduinos bin habe ich zuerst gegooglet und eine programmierung gefunden bei der man aber einen lüfter mithilfe eines poti steuert, dies habe ich etwas verändert, aber nun kommt mein problem: statt das die led auf dem streifen sich dimmen blinken sie je nach frequenz unterschiedlich auf, woran könnte das liegen ? hier noch die programmierung : code: [select] const int ledpin = 3;         // led-strip pin 3 angeschlossen const int audiopin = a0 ;    // audiosignal analogen eingang pin 0 angeschlossen int ledlight = 0;            // variable

pessoal, estou criando um site para uma amiga e ela gostaria que no site dela tivessem vários blogs (ela iria usar para blog dela e das amigas de colégio) e que fosse possível postar comentários nestes blogs. alguem pode me recomendar algum módulo ou uma dica interessante? grato marcos oi marcos, eu recomendo mesmo o tutorial joomla. só tem em inglês, mas em português você vai encontrar muita coisa também. aqui mesmo no fórum tem um tópico com uma porção de links para tutoriais e tals... veja bem, o joomla funciona perfeitamente como um blog por si só. o mais é você equacionar como irá fazer dele o que quer. para estas questões tem uns sites brazucas mto bons: www.joomlaminas.org e www.joomlabrasil.com.br para todas outras: google!

ok, trying update friend's ubuntu installation here.. in update manager, there's no button upgrade distribution. when run, sudo do-release-upgrade says "no new release found". when run sudo update-manager -c there's no button upgrade distribution again. else there try upgrade ubuntu 8.04 installation 9.10? don't it! backup important stuff , clean install. you'll hit world of pain if upgrade, 8.04 9.10! seriously, there ways, wouldn't advise it!

bonjour, j'envisage de motoriser la porte de mon poulailler. pour cela je vais alimenter ma carte arduino via une cellule solaire et une batterie lipo via un shield qui permet de gérer et réguler la tension. je voudrais me servir de l'intensité produite par les cellules pour actionner le motoréducteur (en simplifiant  : pas de soleil ou intensité à 0v, fermeture de la porte car nuit, et supérieure à 0v ouverture de la porte car jour) est-ce possible ? quel sont les connexions à faire sur la carte arduino (car j'ai 2 fils noir et rouge ne sortie de la cellule solaire) et je n'ai pas de 3ème fil pour connecter sur une broche analogique pour pouvoir mesurer l'intensité de sortie. merci de votre aide giloris bonjour, il faut que tu relies le moins à  gnd de l'arduino et le plus à une entrée analogique via un diviseur de tension afin de ne pas avoir plus de 5v en entrée au plus fort de la tension cellule. il faut avoir le schema complet

hey had made own relay board. relays, need use 74hc595 along uln2803. hav taken 3 pins arduino 74hc595 n taking output uln have vcc-12v . uln output, relay pins connected. relay board common vcc. when give power supply , relays trip in program hav low registers. please me figure out. n need overview on programming. hi welcome forum. can please post copy of circuit, in cad or picture of hand drawn circuit in jpg, png? can please post copy of sketch, using code tags? they made  </> icon in reply menu. see section 7 http://forum.arduino.cc/index.php/topic,148850.0.html have got gnd connections joined together? tom...

hi all, i'm trying seemingly simple following error every time insert card. - initialization failed! - couldn't create file... the line below gives me 1 when inserted 0 when isn't. code: [select] reading = digitalread(sdinpin); what doing wrong? thanks in advance, charles code: [select] #include <spi.h> #include <sd.h> // --------- general ----------- int sampletime = 10; long int previous = 0; long int starttime = 0; int sdinpin = 2; boolean starting = true; boolean reading = false; file datafile; const int chipselect = 8; void setup() {   serial.begin(115200); } void loop() {   reading = digitalread(sdinpin);   if (reading) {     if (starting) {       serial.print("starting: ");       serial.println(starting);       loadsd();       starttime = millis();       starting = false;     }     if (millis() - previous > sampletime) {       string datastring = "";       // add data datastring       serial.println(datastring);       data

hi everyone, i arduino mega act reliable controllable (linear) current source. easiest way, figured, use pwm of arduino , somehow convert constant current.   the pwm switches @ 490 [hz] , outputs 5 [v]. current source should have range of @ least 0 [ma] 20 [ma].  i've found off-the-shelf converter ( click here ), costs €220,- , way expensive. i try build pwm (analog) voltage converter , connect voltage-controlled-current-source. problem foresee it's not accurate enough, , need able control output current precisely. are there standard (cheap) ic's solving problem or need build customized circuit? any @ appreciated. why not use this , use this set reference voltage (shown pot in schematic) ?

buonasera tutti, mi presento tutti con questa mia prima richiesta xd, comunque piacere di conoscere tutti voi. allora volevo chiedervi un paio di cose su uno sketch che ho scritto per muovere 2 servo  tramite tasti di un lcd keypad shield ed una scheda arduino.in particolare 2 servo devono muoversi di 2 angoli (0 - 90 gradi) tramite 2 pulsanti, inoltre ho altri 2 pulsanti che utilizzo per switchare tra 2 servo (ovviamente parlo dei tasti del lcd keypad). vi allego lo sketch..... code: [select] #include<servo.h> #include<liquidcrystal.h> liquidcrystal lcd(8,9,4,5,6,7); servo myservo1; servo myservo2; int i; int pos1; int pos2; int pos3=0; int pos4; int pos5=1200; int tens; int switchmotore; int flag; void setup() { lcd.begin(16,2); lcd.print("angle1 angle2"); lcd.setcursor(0,2); lcd.print(pos1); lcd.print("gradi"); lcd.print(" "); lcd.print(pos2); lcd.print("gradi"); } void loop() { switchmotore=analogread(0); if(switchmotore
