The problem was that i tried to power it with 5,07V form a transformer and it didnt work... maybe there wasnt enough current...

Anyone? :-/

I'm a new ArduinoBT owner and I'm trying to get a darn program uploaded onto it... My board is powered by a 4,5V Duracell battery (well.. i actually measured 4,74V on the bat), i have Widcomm BT drivers
I downloaded the 0010 software and had some problems and deleted it and tried 0009... same here, and now i'm runing on 0008.
I paired the board with my pc, connected to it and ran the 0008. Loaded the Blink sketch, and when i press upload, the bt just crashes and in a few seconds its up again... the program says that the board was not found and it cannot upload to it and it says i need to reset it... Then I hold the reset button for 5seconds or so and right after i release it i click upload... the same happens...
IDK what to do anymore... Help me please!

Edit: I forgot to mention, that i already checked the COM port

eh... i just changed the variable names so its more understandable here, but it seems that i forgot a few smiley-wink
and yyes, i does compile... its prolly like Daniel said about the resistors.

Thank you smiley-wink

I just recieved my Arduino board so I'm still trying simple stuff, so don't laugh :-/

I was trying to make a led light light up, whenever you press any of the 4 buttons, but when the program starts first there is a weak light, and when I press a button it lights up a little bit brighter. I just dont get it... I tell the board to keep the pin low when there are no buttons pressed. What is the problem?

Here is the code (the buttons are attached to pins 9-12 and the led is on 13):

int ledPin = 13;
int firstPin = 9;
int secondPin = 10;
int thirdPin = 11;
int fourthPin = 12;
int one = 0;
int two = 0;
int three = 0;
int four = 0;

void setup()
  pinMode(ledPin, OUTPUT);
  pinMode(firstPin, INPUT);
  pinMode(secondPin, INPUT);
  pinMode(thirdPin, INPUT);
  pinMode(fourthPin, INPUT);  
void loop()
  one = digitalRead(whtPin);
  two = digitalRead(bluPin);
  three = digitalRead(redPin);
  four = digitalRead(yelPin);
  if(one == HIGH || two == HIGH || three = HIGH || four = HIGH)
    digitalWrite(ledPin, HIGH);
  else { digitalWrite(ledPin, LOW);}

Hi wayoda!

I have just one little question... where do I get the documentation?  :-[

Hi! I would like to implant my Arduino in some C# applications, but I just can't find any libraries for it. If there is anyone out there who has one, please share it with me  smiley-wink

Thank you ;D

I just got my Arduino BT, and tried to hook it up to the transformator... i tested the voltage with a multimeter first and it said exactly 5,07V. The LED didnt light up... the website says 5,5V is the limit,but it didnt work...  then i hooked it ut to two 1,5V batteries (around 3V together) and it worked... Why doesnt it work at 5V?

i wanna hook up a serial lcd on the arduino, and at the same time interface my comtuter over bluetooth... is that even possible, considering, that the pins 0 and 1 are actually connected to the bluetooth module... could this be done? or maybe solved with I2C? help me out pls
