In this project I am focusing less on the electronics and more on the programming. In my job we are required to know Morse Code, and sometimes learning it can be challenging. I programmed my arduino to flash the led on pin 13 in relation to the Morse Code.

I only have letters and numbers programmed into it, no prowords yet. My next step is to add serial communications so I can change the message or change the words per minute on the fly. I ordered at bluetooth module and I will be able use my phone to control it too. Maybe some more things later but that’s the plan for now.

Here is the code if you want to try it out.

News about the event

• Downtown Oshawa News – I was interviewed
• Digital Journal

This circuit opens and closes a stairway down to a dungeon and moves some stairs out to prevent jumping at the last step.

Check out the flickr set for the day. And I made 2 panoramic photos on my Photosynth page.

Don’t forget to visit the park website for some information about the park. Then go and put your hiking boots on and visit the park.

Anyway here is some news.
-new phone, samsung galaxy s. (but you already knew that).
-broke my leg during basic traning and it’s almost healed now.
-living in Quebec now, but still don’t know any french.
-spent too long at basic, almost 9 months now… something that should have been only 3 months.

I wrote this in march but forgot to hit the publish button. Sorry for that.

This photo is from a trail in the north end of Oshawa, right behind the airport (also known as “Airport Trail”). I was walking along and seen this monarch just sitting there.

I love this camera so much. On the original photo I can zoom in to 100% and see every little detail.
