yeh, i use microsofts calculator for conversions, open the calculator, click view, then programmer =] im off now, see what you can do, if you set the limits lower than you want, then you can prove the function by moving it about on your desk

 

Here is my final code:

// these constants describe the pins. They won't change:
const int groundpin = 18;             // analog input pin 4 -- ground
const int powerpin = 19;              // analog input pin 5 -- voltage
const int xpin = A3;                  // x-axis of the accelerometer
const int ypin = A2;                  // y-axis
const int zpin = A1;                  // z-axis (only on 3-axis models)
const int relay = 0;                  // Output for the relay

void loop()
{
  if(analogRead(xpin)>1101110111); 
  { do relay = 1 };
  else if(analogRead(xpin)<0010001001); 
  {do relay = 1 };
  else(relay = 0)
  if(analogRead(ypin)>1101110111);
  (do relay = 1);
  else if(analogRead(ypin)<0010001001);
  (do relay = 1);
  else(relay = 0)
  if (analogRead(zpin)>1101110111);
  (do relay = 1);
  else if(analogRead(zpin)<0010001001);
  (do relay = 1);
  else(relay = 0)
  // delay before next reading:
  delay(100);
  
}

And these are the list of errors that I get when I try to compile it:

Any advice you can give me to get rid of all these?

 

ah yes,

if(analogRead(xpin)>1101110111); 
  { do relay = 1 };

should be

if(analogRead(xpin)>1101110111) 
  { do relay = 1; }

same problem for all lines, too many semicolons..
your "else" needs to use curly brackets {} in fact you need to use curly brackets in all.. i.e...
if()
{
relay=1;
}
and it doesnt know what relay is.. i assume your compiler is like mplab when i say try #define relay A0, at the moment its just 0...

 

oh and try getting rid of the do.

 

I look at another digital output sample and after changing my code around came up with this

/*
 
 The circuit:
 analog 0: accelerometer self test
 analog 1: z-axis
 analog 2: y-axis
 analog 3: x-axis
 analog 4: ground
 analog 5: vcc
*/

// these constants describe the pins. They won't change:
const int groundpin = 18;             // analog input pin 4 -- ground
const int powerpin = 19;              // analog input pin 5 -- voltage
const int xpin = A3;                  // x-axis of the accelerometer
const int ypin = A2;                  // y-axis
const int zpin = A1;                  // z-axis (only on 3-axis models)
const int relay = 2;                  // Output for the relay

void setup() {
  // initialize the LED pin as an output:
  pinMode(relay, OUTPUT);      
  // initialize the pushbutton pin as an input:
  pinMode(xpin, INPUT);  
  pinMode(ypin, INPUT); 
  pinMode(zpin, INPUT);   
}

void loop()
{
  if(analogRead(xpin)>0001011110)
  { digitalWrite(relay, HIGH); }
  else if(analogRead(xpin)<0010100010)
  { digitalWrite(relay, HIGH); }
  else{digitalWrite(relay, LOW);}
  if(analogRead(ypin)>0001011110)
  { digitalWrite(relay, HIGH); }
  else if(analogRead(ypin)<0010100010)
  { digitalWrite(relay, HIGH); }
  else{digitalWrite(relay, LOW);}
  if (analogRead(zpin)>0001011110)
  { digitalWrite(relay, HIGH); }
  else if(analogRead(zpin)<0010100010)
  { digitalWrite(relay, HIGH); }
  else{digitalWrite(relay, LOW);}
  // delay before next reading:
  delay(100);
  
}

It compiles fine and doesn't throw any errors but i can move the accelerameter all over and smack in on my hand and nothing happens. Not real sure why that is

 

because.. 4g is ALOT.. to trigger 4g, thats.. 40m/s (4*g g=9.8m/s^2)
like i said, you might need to set it lower first, then set it up to your spec..
also, i dont know what you need to do to set it in 2, 4 6g modes?
<edit>
you need to set the microswitches.. set it to 4g, cos thats what we have been aiming for, thats 1 0 on the switches..
then adjust the values so you can have lower thresholds..
also, are you sure that relay is set to a port pin? i.e. an actual pin? no idea how you program an avr io port, but something to check

 

In the code that i just posted i changed the trigger to 1g to see if i could get it to work and that still didn't change a thing

ok, i suggest a hardware check.. comment out your if statement,
have:
relay=1;
delay(1000);
relay=0;
delay(1000);

assuming delay can accept 1000. that should toggle the relay output, so turn it on and off..

I think i may have found out what is going on. When i try to upload the program to the board it says upload complete and then throws the error code of:

avrdude: stk500_getsync(): not in sync: resp=0x00

I did a google search for the code and came up with some things to try. I'm going to try doing those and see if that helps at all

 

cool, report back!

 

Come to think of it I don't know if i even have everything plugged in to the correct place for it to be working right

 

DOH! well sort it out, double check, post images/schematic diagram type things here if you need

 

Ok, Here is a picture of the board with nothing connected to it.

http://www.flickr.com/photos/79051833@N03/6931667130/

The accelerometer is being connected to the three prong analog in ports 1 2 and 3. The relay is being connected to the digital three prong port 2. I believe that is how it is set up in the program but i can't be 100% sure

 

like i said, try a hardware check?
you should hear the thingy clicking? relay ==thingy

 

I can hear the thingy clicking when i first plug it in but it doesn't click much after that

 

thats just because the io is probbaly high, try an oscilloscope?
did you comment out the if statement? and put that relay=0 code i mentioned earlier?

 

Do you know how to remove programs that have been uploaded to the microcontroller. When i was installing the software for it the tutorial said to upload a blink program and for whatever reason that one worked and one of the leds keeps blinking regardless.

 

there should be an "erase" or erase flash button in the compiler/ide that your building your project in.. assuming it has identified the board is plugged in of course

 

Yeah i put

else{digitalWrite(relay, LOW);}

at the end of each if statement. I have the board hooked up to my usb drive of my laptop right now

 

no i mean, comment out the ifs, /* */ style, and just toggle the relay.. make sure the processor is controlling the io.. maybe i misunderstand whats going on here, think its bedtime!
