Re: Programming problem- no error messages. passing arrays in a function. Posted: 23 Apr 2013 03:44 AM PDT Quote what is uint8_t? The datatype you used here: Code: const uint8_t   pinLED_0    =  7;

Re: Bouncing exceeding 200 ms Posted: 23 Apr 2013 03:43 AM PDT Quote from: Grumpy_Mike on April 22, 2013, 03:43:28 PM It looks like you should get some better switches. This, too. $10 spent on microswitch arcade buttons could make all of this moot. http://www.ebay.com/sch/i.htm...

Re: [OT] Un nuovo progetto della serie "vintage": l'OROLED Posted: 23 Apr 2013 03:41 AM PDT parliamone moltissimo mai vista una qualità così bella, nei miei lavori precedenti, con integrati, resistenze ed altro, il risultato sembra buono, ma confrontandolo col tuo non c'è paragone, ma devo ricorrere ad un programma esterno??

Re: Removing elements from array Posted: 23 Apr 2013 03:41 AM PDT OK, I'll narrow it down. Code: icountu <= sizeof(up) / sizeof(up[0]) Can you see it now?

Re: Array di led Posted: 23 Apr 2013 03:40 AM PDT Esattamente proprio così eventualmente si potrebbero anche dividere in gruppi di 50 led

Re: Two I2C lcd displays did not work together Posted: 23 Apr 2013 03:14 AM PDT Have/can you set the displays to have different I2C addresses? A link to the display would help.

Re: Problema accensione led da web Posted: 23 Apr 2013 03:11 AM PDT L'ho aggiunto a tutte le righe e funziona perfettamente anche con 6 led Grazie mille a tutti! Dove hai letto che la "F" serve per evitare il caricamento sulla RAM? Così posso studiarmelo da solo Ringrazio ancora TUTTI per il vostro tempo a me ded...

Re: Problem with MAX7219 Posted: 23 Apr 2013 03:10 AM PDT What happens if you use the 7Segment demo included with the LedControl library? [code]//We always have to include the library #include "LedControl.h" /*  Now we need a LedControl to work with.  ***** These pin numbers will probably not work with your h...

Re: Using an arduino uno and wifly rn 171 to create a wifi traffic emulator? Posted: 23 Apr 2013 03:10 AM PDT Quote wireless traffic emulator Describe what you understand by the this term. If you want to have a traffic generator to saturate your wireless network, use a computer and not a microcontroller, it simply cannot generate enough data for that ...

Tutorial: Low Level Magstripe Reading Posted: 23 Apr 2013 03:00 AM PDT Low Level Magstripe Reading @ The Adafruit Learning System. In order to get raw parsed data out of a magstripe reader, we first experiemented with a MAGTEK Centurion Keyboard Encoder (PN-21073062). We found that although we could get all 3 tracks of data, it was not possible to have it parsed out. We then purchased a raw magstripe decoder head with track 1 reading, the Omron V3A-6 (Datasheet here). By writing some parity checking code, we were able to read the raw data off of the magstripe, and parse it into output that would be 'typed out' as an emulated keyboard using a USB-enabled Teensy. An Arduino can also be used, and the data would be output as Serial which may also be useful. Learn more.

Re: Hilfe bei Schaltplan zum Anschluß von Ventilen Posted: 23 Apr 2013 02:45 AM PDT Hallo Gunther, kannst du den Schaltplan nochmal überarbeiten? Da geht es bei den 12V und GND von der Netzteilbuchse ein bisschen chaotisch zu. An der Buchse steht bspw. +12V, die Leitung geht direkt an den GND vom Arduino.

Re: Große Last, gemeinsame Masse Posted: 23 Apr 2013 02:45 AM PDT Hallo Gunther, danke für deine antwort. jetzt zum testen habe ich die strombuchse, mit 5V vom dem alten, ausgebauten, PC-netzteil versorgt, ich hätte drauf hinweisen sollen. der arduino war an USB angeschlossen. ich wollte erstmal das prinzip darstelle...

Re: Array di led Posted: 23 Apr 2013 02:44 AM PDT Quindi l'accensione è di 1, 2, 3, 4, ...... 250 led giusto?
