News 1130 article re Dillon and me

Dillon and Daddy with the torch!

They let Dillon join be for the back stretch were it wasn't crowded.

Bell Team out in force!

Many thanks to the team for coming out to cheer me on!

Kevin, Justin, Norm, myself, Ryan & Rich.
Missing: Mark and Wallace

Thanks to my folks, Ame, Nash, Harm, Mira, Catherine, Matthew & Michael for coming as well!

First Arduino Sketch - USB/LED morse code generator

I recently got a Duemilanove - of course I wanted to try it out, but all my "bits" are in storage while the basement is renovated.  So, what is something interesting that only uses the built-in LED and the USB serial interface?     Decided to try a morse code generator with adjustable delays to match the proper WPM timing.

//what to do when you only have the builtin led and usb and all your other bits are in storage
//morse code of course!
// set pin numbers:
const int ledPin =  13;      // the number of the LED pin

int incomingByte = 0;
char buffer[1025];
int buffercount=0;

// the follow variables is a long because the time, measured in miliseconds,
// will quickly become a bigger number than can be stored in an int.
long interval = 240;           // interval at which to blink (milliseconds)
int wpm = 5; //stabdard is how many time paris is sent in a min.  Paris is 50 dots durations using standard timing

void setup() {
  Serial.begin(9600);
  // set the digital pin as output:
  pinMode(ledPin, OUTPUT);     
  buffer[1024]='\0'; 
}

void dot()
{
    digitalWrite(ledPin,HIGH);
    delay(interval);
    digitalWrite(ledPin,LOW);
    delay(interval);
}
void dash()
{
    digitalWrite(ledPin,HIGH);
    delay(interval*3);
    digitalWrite(ledPin,LOW);
    delay(interval);
}


void dotdash(char *s)
{
  Serial.println(s);
  for(int i=0;i<5;i++)  //5 as morse has 1-5 ._ per letter
  {
    if(s[i]=='\0')
    {
      break;
    }
    else if(s[i]=='.')
    {
      dot();
    }
    else if(s[i]=='-')
    {

  }
  delay(interval*3); // intra-char delay

This post is to create an area for Lisa to post updates!

Welcome!

Hi and welcome!

We have recently switched our website to blogger, so please let me know if anything is broken!

I'll post my technical musings here....

Thanks,
