About Me

I like to ride my bike. And I like programming arduinos.

Three Things I Learned During This Program

  1. The shorter leg on an led connects to ground.
  2. You should not put magnets by a computer
  3. There are a lot of different video formats that I didn't know about.

Monday's Project Log

You can change how long or fast the led blinks by changing the delay between digitalwrite commands.

Tuesday's Project Log

If you put magnets too close to a computer, you can cause it to crash.

Wednesday's Project Log

The video below was taken by Amirah. It would play in Chrome, but not on Firefox. To get it to work with Firefox, I needed to convert it. I used this command:

$ ffmpeg -i Robot.3gp -ab 64k -ar 44100 -strict -2 Robot.mp4

Then the html to show it on the page looks like this:

<video controls="controls" width="400">
<source src="Robot.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
