ok e questo chip è facile da trovare ? comunque ho altri arduino rotti per lo stesso motivo , non penso vadano bene , grazie dell aiuto , oltre a questo però mi serviva aiuto per il codice dei sensori QTR

The regulator from the ethernet shield gives me 3.3V , so is it the W5100 burned or something? what else do i have to look? the second ethernet shield works just fine with this MEGA. so its not the MEGA fault , just the shield

Why don't you just build an astable version with a very low duty cycle? 2 seconds high, 120 seconds low, that's a duty cycle of 1/60. You will need only one ne555.

Re: Problem with uploading larger programs - maybe bad ATmega chip?

I tried the Serial thing, but no success - if I comment out enought code to be "small" it just works. if I comment out less, so it is large, then it say nothing. Which is consistent with previous tests - I think, that satting LED HIGH would be visible,...

Thanks for that info. That timeout code is the latest change I made just a few days ago.

On a pas dit que ça ne le faisait pas, mais stein dit qu'il ne veut pas modifier sa carte.
En même temps du 115200 bauds par soft faut pas rêver même avec un quartz à 20MHz cela ne doit pas laisser beaucoup de ressource pour faire autre chose.

Re: My rfm12B only works when connected to 5v.

Posted: 14 Apr 2013 02:01 AM PDT

I have run these RFM12B from the 3v from the arduino supply, but they take quite a surge of current momentarily when transmitting, so I fitted a 4700MFD capacitor to the supplypins, and they ran fine.

Re: Iterate through struct

Posted: 14 Apr 2013 02:00 AM PDT

What I showed was an example of iterating through an array of 3 structs. To make that work you'd need to make an array of structs and use the array name rather than myStruct.

It's been too many years since I coded like that. I'd have to look it up to b...

Re: Continuous Rotation Servo - initial power up movement?

Hi, I am trying to let the digital servo motor to rotate from 0-170 degree and then stop. How can I do that? Could you help?
Also I have a digital servo LS-8101F. It says the speed of the servo can be controlled. Can it be controlled with arduino?
