hallo community! es geht um meinen arduino mega 2560 r3. ich habe ein programm geschrieben, dass alle x sekunden eine web-api ansteuert. soweit gut, es hat alles funktioniert. nun habe ich den arduino woanders angeschlossen und es tritt das folgende phänomen auf: der webclient ruft nur ca alle 16 sekunden die url auf. ich habe mir die ausgaben temporär als debug-nachricht in der konsole anzeigen lassen, der webclient wird zwar "gesendet", die api wird aber nachweislich nicht angesteuert. dann habe ich "aus spaß" mal das beispiel "webclient repeat" auf den arduino geladen, auch dort wird nur ca alle 16 sekunden die url aufgerufen, obwohl ich den auf 1 sek (1000l) gesetzt habe. jetzt meine frage: woran kann etwas liegen? ich habe hier ein cat5 kabel, dass ca 10m lang ist liegen, kann es daran liegen? besten gruß napster was bedeutet denn "woanders angeschlossen"? anderer port, anderes system, anderer dsl anschluss?

salve, sono nuovo nel mondo di arduino e volevo un vostro aiuto. volevo averee delle informazioni sui pin di arduino uno: volevo sapere quanta corrente (a) e quanta tensione (v) esce dai pin i/o di arduino uno e quanta ne può entrare. poi volevo sapere quanta corrente (a) esce dal pin 5v e dal pin 3.3v. grazie mille ciao, corri leggere il regolamento e presentarti! lui potrebbe colpire con puntualità svizzera !! poi..... qui  sopra in products leggiti la specifica che fai prima.... stefano Arduino Forum > International > Italiano > Hardware (Moderator: leo72) > Corrente e tensione nei pin di Arduino UNO arduino

so, i'm pretty sure has been discussed in form or another, it's wanted chat about. it's pretty clear lot of raspberry pi users use them gaming purposes, emulators , such. honestly, lot of more software behind (retropie mainly). so, why not create device users want software support, less concerned pricing? me, personally, i'd happily pay $100 or if dreamcast , n64 games running on pi device. assume a8 processors, dumped pi 3 board (the chips , controllers associated current pi 3 anyway) allow same software run, @ faster speed, right? admittedly, i'm not computer expert, them. budget market more covered 0 , pi 3. why don't expand , focus on enthusiast push products harder else? know it's not original plan, following market thing. don't suppose there higher end products work out of box retropie there? dirthurts wrote: ↑ tue oct 03, 2017 6:17 pm it's pretty clear lot of raspberry pi users use them gaming purposes, emulators , such. honestly, l

hi there! i'm working on project involves 660 ws2812b leds. it's star 4 stripes facing 4 different directions (it's bit more complex that's easiest way explain it). as these leds used actual light room, used @ 100% brightness (white). means 660*0.06 amps = 39.6 amps. the problem is: can't place power supply in middle of star (as pretty ugly), thought using 4 * 10 amps power supplies. budget limited, thought cheap this: ebay can connect ground of 4 power supplies create common ground? using 1 single power supply impossible, voltage drop way high (that's think @ least). any on great! and sorry possibly bad english? the more can distribute load better. why not 12 20 smaller dc-dc converters fed 1 12 24v/40a p.s. ?

buonasera tutti, vorrei porre un problema che ho riscontrato con la gestione di una struttura dati implementata in un file .h di una libreria per la gestione dell'integrato mcp79410. premetto che il problema si pone compilando con la versione dell'ide 1.6.9 mentre con la versione 1.6.4 il problema non compare. la struttura è così composta:    typedef union timekeeperdate {             uint8_t  datebyte;       struct {          uint8_t dateone      :4;          uint8_t dateten      :2;          uint8_t free      :2;       } datebit;    } timekeeperdate; praticamente non si riesce caricare un valore diverso da 0 in "dataten" con la versione dello ide pari 1.6.9. se invece si lavora sul byte, ovvero "datebye" il dato viene caricato correttamente. questo comportamento anomalo non si verifica con la versione 1.6.4 dello ide. avete dei suggerimenti? vi ringrazio buonasera, non avendolo tu ancora fatto, nel rispetto del regolamento, t

buongiorno tutti, sono theoxide e sono nuovo del forum. ho un piccolo problema con un progettino . devo controllare otto relè attraverso una password inserita da tastiera. fin qui niente di strano. il problema è che le password dovrebbero essere 4 ed ognuna di esse dovrebbe controllare due relè attigui. nella fattispecie ogni relè ha assegnato un digitalpin, il problema è che non come assegnare differenti password ad ogni gruppo di due d-pin. in poche parole, ripeto il concetto, inserendo una determinata password si assegnerà il valore high solo e solamente ai pin associati quella password, mentre gli altri manterranno li valore low. utilizzo la libreria password per gestire le password, ma non come importare più di una password ed assegnarla ai differrenti pin (a logica suppongo vada dichiarato in loop setup. spero riusciate ad aiutarmi. theoxide inizia impostare lo sketch con una password e un relé, poi vediamo di estenderlo. quando hai fatto, postalo.
