confusion regarding seperate control of two servo motors

Posted: 01 Jun 2013 02:35 AM PDT

Hi,

Sorry if this is noobish, I am quite new to programming for Arduino. I wish to have several servo motors move at random intervals an entire 180 degrees and then back again immediately. I programed this successfully for one servo, but when I attempt...

Re: Leonardo freezes using I2C Accelerometer

Posted: 01 Jun 2013 02:33 AM PDT

I don't know, but I do know why the Leonardo is different.

The Leonardo detects a digital input as a '1' at a lower voltage. That makes the Leonardo compatible with 3.3V signals.
You could try without the 330 ohm resistors.

The Leonardo uses a software...

Could you check your wiring once more ?
Could you upload a schematic of how you have it connected ? or a photo ?

Ciao

quando posti uno sketch o programma devi usare gli appositi tag "CODE"
hai fatto un po' di confusione:

Code:

int pin1=1;

il pin 0 e 1 sono usati dalla seriale, quindi se utilizzi Serial.begin() di conseguenza serialprint non puoi utilizzar...

I appreciate your reply.

Yes, my client uses the same DHCP server.
I have no firewall on my PC.
My router with setup free to all, no restrictions.

When I test with port 80, it works fine.
I did try port 23, and also function well.
When I try to port 21...

Re: Switching two batteries with DPDT relay

Posted: 01 Jun 2013 02:07 AM PDT

Much obliged for the helpful advice, thanks.

Greynomad, looking into it, I think my needs for the system differ enough from yours to warrant the relay. The controller seems to have difficulty dropping out of absorb with much timeliness, and especially ...

Sorry it took a while smiley-lol

, I was thinking what the Arduino could do, but you want to run a program on the PC.

It would require a program on the computer that communicates with the Arduino via a serial connection (the virtual serial port of the Arduino ...

arduino as a remote device

Hi guys,

I am using an Arduino Uno on which I connected an xbee S2B module and an em-406a GPS. At first, I was using its usb port to supply it with power, but I want to make it a remote device so I connected a 9V of 280mAh battery. For some reason the ...

Hi !

First I want to apologize for my bad English.

For a long time I try to do the following thing:

That helped a little bit as the amount of times it stops in a certain time interval has dropped but it still happens occationally

Non puoi provare a spiegare la tecnica di realizzazione di un accordatore d'antenna, in modo da iniziare dal circuito hardware e poi passare alla programmazione? Non è detto che non risolvi qui se fornisci le necessarie e dettagliate informazioni.
