mitcho : I see your BT is "100M" , it like the one I used, and I have try the  9v battery, but it only can work about 30 minutes ,then the voltage will down to 7.5v , then the BT can't work well .

Now I use three li batterys(3.7v,700mAh) , the voltage of them is 10.8v , and it can work above 4 hours.

Hi ! mitcho , I write to arduino with the bluetooth everytime now , you should make sure that :
when you write to arduino , I icon of bluetooth should be green , because the bluetooth connect will cut off when the com of bluetooth is closed 10s.

Yes, you can Write your program to the arduino board using wireless bluetooth, I do it every time , it works well. And wiring board can do it also , just disconnect USB , and connect the BT to the serial0 , then it will work.

Thank you beltran!

It looks better now!

I always want to contribute something what I can do for Arduino , because Arduino give me much happy time and the people here are very friendly , but I am not good at AVR and JAVA, so can't do the useful thing , only share some experience about using Arduino.

Thank you beltran!

I have add the way I use to the wiki , Sorry about my English , I hope I can explain it clarity, if you have any difficulty , you can leave a responses in my blog :http://eiart.net/blog/archive/232

And I hope someone speak English well can help me to fix some English syntax in the wiki , thank you!

Hi! I want to add something about "Director&Arduino" to wiki ,but it need username and password, and I can't find the "register" , can anyone help me ?

I see the "Arduino + Director" , the post there need a "SerialXtra" ,but it not free(it cost $75), I know a free way to use Director communicate with Arduino, that is use "ActiveX" , there is "MSComm" free for all windows users, I have a post about it in my blog: http://eiart.net/blog/archive/232  but it is in chinese , I want to add a english one to the Arduino playground, but I can't edit it.

Hi !
I only write some articles in my blog about it (but only in Chinses) : http://eiart.net/blog/tag/robot

It's a net control robot , you can control it , see it ,  receive the date from it  in the browser(with flash player)

but the server is just my PC , so I can't open it all the day.
and I make a video of it , you can see at : http://www.eiart.net/robot/   but it is big (30M, 20min)

If you want to try , you can leave a time(the time here is  UTC+8)as a reply here(english) : http://eiart.net/blog/archive/218
then at that time we arranged , if I open my server , you can try to  control my robot.

 The big board used to control the motor of my robot , you are so luckly  smiley-wink,  you can use 5v to power modem , it make things very easy , if I live at USA , I will buy one modem like yous , but I in China , the postage is very costly  smiley-sad

Hi ! mitcho . I only know little English ( I'm a Chinese) , my email : fallen11
  • gmail.com , hope I can explain  clarity in English.

and my moden is very small : 1.5cm*2cm , you see in my pic is the whole board.

Hi! mitcho , I had already add a bluetooth modem to Arduino last month , and it works very well , you can see the pic :

I don't know your bluetooth modem works at 3.3v or 5v , my modem is work at 3.3v ,so I need to turn 5v to 3.3 .  the leaved things is just connect the pin0(Rx) of Arduino to the TX of your modem , pin1(Tx) of Arduino to the RX of your modem , than connect the BT to your PC or PDA , you can get the date from Arduino and can send date to it just like there is a series cable , and you can use  Arduino IDE  to download program to the board via BT modem .
41  Forum 2005-2010 (read only) / Frequently-Asked Questions / how to set up an interrupt service routine? on: March 30, 2006, 01:10:07 am
Hi ! I see a post here : http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1143470863
Oliver Keller say :"I set up an external interrupt service routine, that's listening on pin 8 (the only pin that can do that on an arduino board). "

I very want a way to set up an interrupt service routine in Arduino ( timer interrupt and external interrupt ) I see his code :
<code>
void irHandler(void){
// external interrupt service routine

  timeL = ICR1L;  // read time since last reset
  timeH = ICR1H;
  pattern[count]= (timeH << 8 ) | timeL;
  //pattern[count] = millis();   //another attemp, I don't which is more clever
  count++;
  somethingHappend = 1;
}

timerAttach(TIMER1INPUTCAPTURE_INT, irHandler); //attach service routine
</code>

but I can't find the cmd "timerAttach" in Arduino , Is there a way to set up an interrupt service routine?
if somebody know that , could you tell me a example ? thank you !

and I see the PinMapping : http://www.arduino.cc/en/Main/PinMapping
the int0 and int1 is pin2 pin3  , how to use them , and why Oliver Keller say :"that's listening on pin 8 (the only pin that can do that on an arduino board). "?

thank you !

Hi ! we can get it work now ! smiley-wink

if you want to use "2-Pin Ceramic Resonator" ,  you need to add two "27pF" between XTIN, XTOUT and GND, then it will work well !

And maybe there is mistake in the CAD file , the USB " + "and "-" are  opposition !!!   I cut down the "USB head" and link them opposition, then it can work.

sorry about my poor english , there some pic of it :

Hi ! I see the "FT232BM USB UART IC Data Sheet" carefully today.
The added circuit of your board is for the "TXLED" and "RXLED" , so they are not a needments of this board , isn't it?  

and I can't find a "1M resistance" for the "3-Pin Ceramic Resonator" in the board , but there is one in "FT232BM USB UART IC Data Sheet : http://www.ftdichip.com/Documents/DataSheets/ds232b18.pdf"

if we want to use "2-Pin Ceramic Resonator" , could we add two "27pF" between XTIN, XTOUT and GND?

Thank you!

Hi !

we make the USB board in "http://www.potemkin.org/uploads/Pid/arduino_usb.zip"

and we find it is very different from your USB board in "http://arduino.berlios.de/index.php/Main/USBAssembly"

can it work ? or it is 1.0 and yours is 2.0?   Can it use the newest bootloader?

and we can't find "OSC, 6MHz oscillator, 3-pin" , can we use "2-Pin Ceramic Resonator" instead?

And could you open the CAD files of yours board ?
we are in China, the postage is too costly for our workshop , so we want to make it in China, Thank you!

Hi! sorry about my poor English.

RX at P0 , and TX at P1 , I use the "TTL" direct control a serial camera or a BT module , it work well!

RX-- device's TX
TX-- device's RX
Gnd-- Gnd

if the device is use Rs232 ,you may need a "3223" to conversion TTL to RS232

sorry about my poor English. I hope you can understand me .
