| Re: General book to learn Electronics from zero? Posted: 28 Apr 2013 02:59 AM PDT I would possibly look to some of the online university courses for that sort of treatment - such as the MIT one: http://ocw... |
| Posted: 28 Apr 2013 02:58 AM PDT Je n'arrive pas à solutionner mon problème... Mon code compte le passage d'objets devant une cellule (photoresistance éclairé par un laser), aucun soucis de ce coté là, l'incrémentation fonctionne parfaitement grâce à la commande compteur++. Là ou tout... |
| Posted: 28 Apr 2013 02:56 AM PDT Hi guys, i was improving my 'domotic control panel' while it started givingme an error on line 13 "error: expected unqualified-id before 'else' " independently on whatever is line 13 (i can cut line 13 and i will anyway find this error)... is that a p... |
| Posted: 28 Apr 2013 02:55 AM PDT Si è l'Arduino uno e no, non ho attaccato niente su quei pin, fra le altre cose mi rimane il pin del led acceso fisso. Ho provato il reset che si trova un po' googlando, staccando il cavo usb e tenendo premuto il reset reinserirlo e caricare uno sket... |
| Posted: 28 Apr 2013 02:55 AM PDT I relé stessi sono isolati tra bobbina e contatto. Un optocoppler non migliora l' isolamento. Penso che giá usi dei alimentatori differenti per la parte Arduino - relé e la parte audio. Ciao Uwe |
| Posted: 28 Apr 2013 02:44 AM PDT Bonjour je continu à faire des recherches dans mes bouquins, dans mes cours de "mon-club-elec", je fais aussi des essais mais maintenant je me pose la question: est-ce possible ? Si vous avez une solution elle sera la bienvenu ! en attendant je continu... |
| Re: Ardutester - Arduino Component Tester Posted: 28 Apr 2013 02:44 AM PDT Secondo me anche la parte delle resistenze è da rivedere..... Si, come dicevo ieri sera, tutta la parte dei passivi, anche se sono ad un buon punto ed entro breve pu... |
| Re: [HOWTO] Guida (più o meno) completa all'utilizzo di Moduli Bluetooth Posted: 28 Apr 2013 02:43 AM PDT Io invece, lavorando spesso con iOS, ho optato proprio per la soluzione WiFi che ... funziona allo stesso modo, senza tanti casini, indipendente dalla piattaforma con cui coll... |
| Multitasking oder wie löst man das Problem? Posted: 28 Apr 2013 02:40 AM PDT Hallo Leute, Habe eine Kombination aus Mega ADK und 2 TOS-100 Schrittmotoren. Die Ansteuerung der Motoren funzt soweit einwandfrei. Nun möchte ich aber während der eine Motor dreht, z.b. alle 1000 steps oder alternativ alle 2s ein Relais über einen Out... |
| Re: Hilfe bei Schaltplan zum Anschluß von Ventilen Posted: 28 Apr 2013 02:40 AM PDT In meinem Schaltplan ist doch der Optokoppler auch "nur" mit GND und einem Ausgang verbunden. Nein.In deinem Schaltplan ist Pin 4 mit der Basis des Transistors verb... |
| Re: Arduino Uno r3 Serial Com Port Not Recognized Posted: 28 Apr 2013 01:55 AM PDT I'we done exactly as you told me, but it stil doesn't work. I'we removed the atmega chip from my spare arduino (the working one), connected the pins as you described and connected my spare arduino via USB to my computer. This way I got power to both my... |
| Re: Smallest + cheapest AC to DC electric module Posted: 28 Apr 2013 01:53 AM PDT Hi, Not sure if this is what you're looking for, but recently I've been powering projects with compact USB phone chargers (like these). They put out up to 2A and all the work is done. I just b... |
| Re: BMP085 the apocalypse has come Posted: 28 Apr 2013 01:51 AM PDT Hi rocket1172, You could have created a new topic: "BMP085 + Nano not working". Did you go through the Adafruit tutorial ? http://learn.adafruit.com/bmp085 Could you create a new sketch, and copy-paste the i2c scanner into it. http://playground.arduino... |
| Posted: 28 Apr 2013 01:50 AM PDT Se l'idea è quella di pilotare i led dai pin di Arduino sia come anodo che come catodo, bisogna poi anche fare i conti della somma delle correnti per gruppi di pin e per corrente totale. Con così tanti led credo che sia più saggio interporre qualche al... |
| Re: (Constant Voltage Source) + 1 Transistor + 1 Resistor + 1 LED = Safe? Posted: 28 Apr 2013 01:48 AM PDT Using a transistor to replace a Resistor's job, eg, 10k base pin, to switch the resistor on, then using a 2nd resistor to limit the current to the diode? why not pick a re... |
| Re: BMP085 the apocalypse has come Posted: 28 Apr 2013 12:44 AM PDT Hi guys and thanks for the opportunity to make my first post. I am having this exact same issue with my BMP085 connected to Arduino Nano using the same Adafruit library......And getting the exact same values!! Any help will be much appreciated. Thanks. |
| Re: Calcul vitesse de déplacement avec capteur infrarouge réflectif Posted: 28 Apr 2013 12:43 AM PDT J'ai un projet de calcul de vitesse. J'ai donc commander deux capteurs infrarouge réflectif. Le but étant de déclencher un chronomètre lors du déclenchement du premier cap... |
| guidence on speed measurement using optical encoder Posted: 28 Apr 2013 12:43 AM PDT hello, I am doing a project on self-balancing bicycle. As a part of that project, I need to measure the speed of the shaft of the motor which is driving the cycle. I am using an optical encoder MOC7811 to measure the speed. I am using Arduino uno micro... |
| Re: Controllare uscita arduino da file presente su SD Posted: 28 Apr 2013 12:42 AM PDT Allora mi scuso perché avrei dovuto intervenire anche in quella occassione. Sarebbe giusto invitare di presentarsi. (neanch io mi sono mai presentato) Ciao Uwe |
| measuring current using arduino. Posted: 28 Apr 2013 12:42 AM PDT hi. I want to measure current provided by the Solar Cell using the Arduino,the Solar Cells have the rating of 35 Watts to 400 Watts with a Nominal voltage of 12 volts. I searched over the internet and found that a hall effect sensor can do this for me... |
