Materials:

Ikea: Metod/ Maximera 40cm (490.243.06)
Ikea: Trofast (800.892.39)
Ikea: Utrusta 40cm(802.046.73)
Ikea: Variera Drawe mat (800.128.53)

Trixie 2-Way Cat Flap door
Arduino Uno single-board microcontroller
Adafruit PIR motion sensor
Adafruit Neopixel Stick 8x
Metal Pushbutton

Some cables and a plastic box that previously housed a soldering iron from Biltema.

Description:  

I wanted to hide the cat litter box in our small bathroom. Only problem was that it was so well hidden and odor free that I forgot it all the time! :( . Problem was then solved with a programmable micro-controller, motion sensor and a led strip with 8x individual controlled led’s that could change colors. Led strip work as a counter and change colors based on how many times the cat enters the cabin. It resets the counter when the button is pushed.
1-4x   = Green
5x     = Orange
6-7x   = Red
8x     = Pulsing Red and Orange

Future update plans:
* Larger and higher plastic litter box.
* Fancier wiring.
* Add a GSM module to the controller and make it send text SMS when the box needs to be emptied, or when the cat breaks a certain visit/day/time pattern.

    Thanks!!

    It has really fulfilled the purpose it was made for, no odor and have never forgotten to clean it. Also have updated the “hack” quite a lot since the post was made. New litter box and new controller box. Dunno how to update the images and description here tow.

    You should sell (or get a patent on) this idea, especially if you get the app working ^^ awesome!

  8. Cassie says:

    Brilliant. This is very Instructables worthy.

    Very compressive. You should post in on instructables.com with schematics and code. I also have the same problem and certainly going to do the same now I see this.

    Cheers.
