When we setup Idovers board all we did was load the sketch and read pin 4. he was never attached to my project board.

I jumpered pin4 to pin6 and used pin6 in the sketch and all is well.

I have since put my shield back on and everything is now good to go. I just cant use pin 4.

btw i am on Vista as well.

there really isnt. I was using a shield. and part of it wasnt working.

After tracing everything out i detected that pin4 was going high but just barely. So i simplified the code down to the bare minimum and posted it here.

I then uploaded it to someone elses board and found the same thing.

They then expanded the program to try out 3-4 interfaces and saw the same thing.

We checked it with a meter, any pin but 4 would go high for a second and read 5v.

pin 4 would go high and read about 1.5. ALso wanted to note that all testing was done on a bare arduino no shield attached.

decimilia...

i tried it on mind and another guys at the user group i was at today...

we also added pins 3 6 7 all of them produced 5v as expected.

So i have created a shield that uses pin 4 and discovered a problem.

Code:

int outRam = 4;

void setup() {
  
   pinMode(outRam, OUTPUT); // Fire Ram output
  }

void loop (){

          digitalWrite(outRam, HIGH);
            delay(1000);
         digitalWrite(outRam, LOW);
         delay(1000);
 }

What i see when pin 4 goes high there is minimal voltage on it only like 1-2 volts. if i change the pin to 12 or any other pin there is no issue. I duplicated this on 2 seperate arduinos. and this is with no shield just measuring the the voltage on the pin.

On pin 12 i obviously see it go to 5v.

Thanks for the help.

How about if i build it. ill send you one and you can code it?

Zitron, If you want to help me put together a board ill Order 2 and send you one for free...

I thought about making an arduino shield, but the i would prefer to have it as small as possible and just run a wire since its going to be on top of your head or glasses.

We can use the LIS302DL - $12.95 sparkfun
and the LISY300AL Single axis Gyro - $11.95 sparkfun

that lisy300al should give you about 100x better capabilities of controlling drift.

COuldnt you use a dual axis Gyro only and skip the accelerometer?

just wondering about wayts to simplify.

the Atmega 328 TQFP package with preburned bootloader?

im trying to make a really small board and would not like to build something else to burn 5-6 boards.

Thanks for the link. I think i can survive with those kit

Sorry for the typo on the 86000 as well

CANCELED!

seeing as how nobody sells a large pack of resistors cheap with the variety i want. i am going to do my own.

I have a supplier that can do 100 each of 86 different types of resistors 1/4 watt carbon film  for $28.

That is 86,000 resistors for $28.

I need 10 total people to join, i have 3 so far, I have offered this to the atlanta arduino group

Once i have 7 People Commit to buying, They can send me $28 via paypal. and should recieve their resistors in about 2 weeks.

Sorry US shipping only.
