than ill write it back, and ill write also an autosave into the arduino ide smiley-grin

anyway to get it back to something more readable ?

well how it looks like ? assembler code ? smiley-grin

hi ,
i've got a problem ... i was working when the power shutted down ... and i've got just an old old save of my work, but i've updated the arduino just 2 mins before the blackout ... is there a way to retrieve data from the arduino ?

chip aint overheating, and everyone that used this kind of motors told me that need a pwm to ~20khz

anyway i'm trying at different frequencys but i dunno if i'm doing it in the right way ... 'cause seems no difference between frequencys

Hi, i'm trying to modify pwm frequency to fit to my DC motor, i think i would need at least 20khz, the problem seems that i'm not good at it smiley-grin

i'm testing this code :

Code:
//First clear all three prescaler bits:
int prescalerVal = 0x07; //create a variable called prescalerVal and set it equal to the binary                                                       number "00000111"
TCCR0B &= ~prescalerVal; //AND the value in TCCR0B with binary number "11111000"

//Now set the appropriate prescaler bits:
int prescalerVal = 1; //set prescalerVal equal to binary number "00000001"
TCCR0B |= prescalerVal; //OR the value in TCCR0B with binary number "00000001"

this should bring my pin 5 and 6 to 64khz ... but no luck, my motor seems to still have problem, when i increase the duty cycle it spins , not at full power, and in 30sec it stops.

(i'm driving it with an SN754410NE, wich i used with some other smaller dc without any problem)

when i connect the motor to the +5V from my generator it spins like hell ...

its so frustrating ...  :-/

hi, i'm trying to interface my arduino with winlirc, but i cant find how to do it :S i managed the signals with this code and works very well .. but i dunno how to interface it to winlirc, what kind of data do he expext from usb serial ?

any idea ?

i'm trying to read an rc-ir remote to replicate it ...

Ciao a tutti, scusate se ho latitato un po ma il lavoro mi sta schiacciando e il tempo non è mai abbastanza ... a mio avviso dovreste provare a vedere di standardizzare di piu le cose a lato elettronica, provate a fare un controller con arduino che si interfacci a dei booster standard l298\l287 cosi in caso ogniuno puo sostituire i pezzi come meglio crede smiley-wink

comunque sono in arrivo delle sorpresine interessanti smiley-wink penso in una settimana massimo due avrò qualcosa di bello da mostrarvi smiley

ora come ora sono piuttosto incasinato... devo prima preparare altri progetti, penso di avere un po piu tempo verso metà mese circa, magari ci ributto un'occhio

si tratta pur sempre di 2 pezzi di ferro lavorati ... non penso che per le 3 guide e le 3 chiocciole si spenda piu di 25€

io il sito che ha quelle da 12 con le chiocciole l'ho messo nel primo post sin dall'inizio cmq ... volendo basta ordinarle da li, per chi è a milano hanno anche un rivenditore fuori milano.

teoricamente ci dovrebbe essere una configurazione con 2 pnp per pilotare i booster con 2 cavi
