I got an idea for the "Make It Grow" Contest, but I had a problem, my soldering iron broke. I ordered a new one but it hasn't arrived yet!
After carefully thought about the project I decided to go with it but instead of solder the components to the PCB I would used the breadboard and my Palm Arduino for the project.

I called this project "Desktop Bonfire."
I used Lego Bricks and Plates to make frames (or bonfire) around my Palm Arduino with the tiny breadboard attached on top of it. I used 5mm LEDs (Red, Yellow, and White) as a combination of the color of the fire lid at the bonfire.
Then I added the straws for the soda (I got it from the fast-food vendor, and it is a perfect fit to 5mm LEDs, picture in Step 2) on the LEDs to make the LEDs glow more than usually and make light  from LEDs more visibility.

I connected all the LEDs to available PWM (Pulse Width Modulation) pins - D3, D5, D6, D9, D10 and D11. And I programmed the Arduino to randomly brighten or dim the LEDs, as the effect of the bonfire (Arduino sketch is available in Step 4.)

By looking at it, it does make me feel like sitting around a warm bonfire during the short day in Winter.
