1  Using Arduino / Networking, Protocols, and Devices / Re: More than 127 Arduino working together on: April 07, 2014, 04:15:57 pm
You can have a switching arduino between each two networks, it has a I2C interface on one side and a software or external hardware I2C on the other side. Each arduino would have a special address within it's network and each network would have an ID/address. Each normal arduino would send data with these two addresses, all arduino's on the same network would interpret it to see if the device address is its or not, if the network address is different, all arduinos on the network would ignore that data except the switch arduino which sends it to the other network or to another switch for another third network.
2  Using Arduino / Networking, Protocols, and Devices / Re: how to get the RSSI values from a bluetooth modem? (HC-05) on: April 07, 2014, 09:33:27 am
Guys try sending this:

AT+INQM=1,1,48

then sending this after it:

AT+INQM?

Tell me how that works out for you.
PS: I have a pair of HC-05 but I never had time to try them.
3  Using Arduino / Networking, Protocols, and Devices / Re: Interfacing with a 3G USB Modem on: April 07, 2014, 09:24:35 am
To PaulS: why are you so mean ?!
To vik09: I guess it's doable but you need the arduino to be a usb host controller, unless you have a due, tre, intel galileo or any other arduino board with built in usb host/otg, you need a usb host shield. for powering the modem, it ususally consumes relativley high power compared to other usb devices such as pen drives, so powering it through the arduino's built in voltage regulator is probably not a good idea. For the software part you need to search the internet a bit.
4  Using Arduino / Networking, Protocols, and Devices / Re: Unable to configure ethernet with Netgear router on: November 07, 2013, 04:56:59 am
We tried it with two arduino uno (R2 & R3) and an arduino leonardo (R3), it works with all boards but on my friend's network (he has a 3COM router and a ruckus access point) but he has the dhcp range from 192.168.1.2-192.168.1.254 so we edit the code accordingly. Obviously the SPI bus works, we even tried an SD card and it works. We need more help please.

Nothing happened, it continuously fails to get an IP address, ideas ?

This is my code:
/*
  Web  Server
 
 A simple web server that shows the value of the analog input pins.
 using an Arduino Wiznet Ethernet shield.
 
 Circuit:
 * Ethernet shield attached to pins 10, 11, 12, 13
 * Analog inputs attached to pins A0 through A5 (optional)

#include <SPI.h>
#include <Ethernet.h>

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
int mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
int ip[] = { 192,168,0,177 };
int dns[] = { 192,168, 0, 1 };
int gateway[] = { 192, 168, 0, 1 };

// Initialize the Ethernet server library
// with the IP address and port you want to use
// (port 80 is default for HTTP):
Server server(80);

void setup()
{
  // start the Ethernet connection and the server:
  Ethernet.begin(mac, ip, dns, gateway);
  server.begin();
}

void loop()
{
  // listen for incoming clients
  Client client = server.available();
  if (client) {
    // an http request ends with a blank line
    boolean currentLineIsBlank = true;
    while (client.connected()) {
      if (client.available()) {
        char c = client.read();
        // if you've gotten to the end of the line (received a newline
        // character) and the line is blank, the http request has ended,
        // so you can send a reply
        if (c == '\n' && currentLineIsBlank) {
          // send a standard http response header
          client.println("HTTP/1.1 200 OK");
          client.println("Content-Type: text/html");
          client.println();

          // output the value of each analog input pin
          for (int analogChannel = 0; analogChannel < 6; analogChannel++) {
            client.print("analog input ");
            client.print(analogChannel);
            client.print(" is ");
            client.print(analogRead(analogChannel));

          currentLineIsBlank = false;
        }
      }
    }
    // give the web browser time to receive the data
    delay(1);
    // close the connection:
    client.stop();
  }
}

I have nothing in the SD card slot, I have tested this on arduino uno R2, R3 and leonardo R3, same result on all three.
7  Using Arduino / Networking, Protocols, and Devices / Unable to configure ethernet with Netgear router on: November 04, 2013, 07:07:40 am
I recently bought an original wiznet W500 r3 ethernt shield and it works fine at my friend's home but at mine it can't access the internet. All cables are fine and I have a Netgear DGN1000 router. The router ip is 192.168.0.1, the DHCP rang is from 192.168.0.2-192.168.0.254. I'm just confused because i just don't know what's wrong ,I even configured the shield to  use an IP in the DHCP range with dns as on the router config. page and gateway as the router ip ....any help ???

Thanks Mr.Carpenter, but my lcd is 128*160 pixels and your library supports only 128*128, suggest a modification or add it to your drivers list pls,thx
9  Using Arduino / Project Guidance / Re: directly driving 4 pager/vibe motors? on: January 11, 2013, 10:31:15 am
You can use a uln2003(a) darlington array chip that is very popular but you tie the other end of the motor to vcc as it inverts the signal. It can drive up to eight or seven motors simultaniously (i dont remember very well) and it has internal protection - though it may be an overkill to use it, thank you
10  Using Arduino / Project Guidance / Re: Interfacing sixaxis controller to arduino via bluetooth module on: January 06, 2013, 10:44:44 am
Thank you for replying, I mean the Sony playstation 3 sixaxis dual shock 3 wireless controller. I don't know how to figure out the protocol and I can't find it while searching. I think I found something but I can't understand it can someone explain it "wiki.ps2dev.org/ps3:hardware:sixaxis" and this "wiki.tinyclr.com/index.php?title=PS3_Controller" thanks again in advance
11  Using Arduino / Project Guidance / Interfacing sixaxis controller to arduino via bluetooth module on: January 06, 2013, 08:10:16 am
Hi, I recently bought a bluetooth module (HC-05) (I think its the one seeed use for their bt breakout module thing) and I want to use it to connect my arduino uno board to a sixaxis controller. I need a link to the protocol the sixaxis use to connect and send data so I could implement it in my code. I can manually pair it to any bt address I want with my pc. The bt module can be configured as master or slave.

13  Using Arduino / Installation & Troubleshooting / Arduino Uno R2 (USB device not recognized) on: December 29, 2012, 12:50:34 pm
I left my arduino for a while then when I came to connect it to the computer it says "USB device not recognized" so I thought the problem is with the pc then I connected it with the laptop it said the same. I think the arduino's atmega8 (responsible for usb to serial) got it's code damaged or has burnt out because the L13 led flickers when I reset the main atmega328 so its not the main chip. I also can't find the code for this atmega8 can anyone post it please ? windows7,uno R2,windows xp (laptop), arduino worked before on both machines. PLEASE HELP ASAP, THANK YOU.

While I can measure coil resistance with a multimeter, how can I measure the drive voltage?
