  LED time piece • v03 • PWM 

  Went minimalist for this iteration of my timepiece.  My new role for this prototype is a vertical light projection, perhaps for use in a bedroom at night.

  Red Green and Blue mix together like a colored venn-diagram displayed on the ceiling, or perhaps a wall if angled as such.  It is a relaxing effect, and i think adding PWM to the fading of each LED (which is now down to a record-low 3!) added a lot to the overall piece.

  Here is my code. I approach the for loops in 2 different ways, one by straight forward execution after an if statement, and another by creating individual functions for each LED.  Using the function method, I can pass in random numbers that are decided earlier in the code.  Overall, really sloppy, and once I choose a method I feel most appropriate, I will stick to that one.

  Ira / Still counting sheep2… 

  I find the way to make my counting sheep prototype as a more compact book. I worked mostly on the hardware part, tried to find the most efficient way to connect everything together. I just started to figure out how Arduino's programming language works, so I still need to work a lot on it. For the next prototype I will mostly concentrate on the code part, and I will try to finalize the overlook itself.

  Passage of time v2.5 with Switches 

  I added switches to the fourth iteration of the passage of time. 1 rocker switch for on/off, 1 toggle switch which switches between 2 patterns, 1 momentary pushbutton switch that changes the pattern when the toggle switch is up. The switches are mounted on a separate short box with holes drilled using the dremel tool and attached to the bottom of the taller box. All the switches are hooked up to the Arduino using a breadboard.

  Ira / Still counting sheep… 

  Still counting sheep as a time passage project, but I decided try a totally different iteration.
  I've tried to make it a book with sheep. The prototype came out a little bit to big that I wanted it to be, and doesn't really have a feeling of holding a book.
  I do like the paper patterns, it makes the blinking light more softer ( as I already did in my first iteration).
  The code is still the same one, for the next step I really need concentrate in the code and the hardware.
