This week the Diwali festival starts so it is time to decorate your home with beautiful diyas
. To add a little bit of originality to it Elektor.Labs has come up with a great diya that you can build and program yourself. Slow animations, fast blinking or simply as a multi-color lamp, it is all possible with this design. And for those who don't celebrate Diwali, this project is also perfect for Christmas.
The Diwali or Deepavali festival
is the Hindu festival of lights that celebrates the victory of light over darkness. Diwali – celebrated in many countries all over the world – doesn’t have a fixed date and this year it happens to begin on November 11th. Similar festivals like Yalda and the Roman Sol Invictus were celebrated in ancient Europe and there are probably many more examples to be found in other cultures. It is all about light and the people you love.
we play a lot with light and LEDs and every year we dream up new circuits that have no other purpose than to please the eye. For Diwali we propose a lamp
consisting of 11 red, 11 yellow and almost 11 green LEDs placed in a circle (32 LEDs in total). The LEDs are controlled by an ATmega328 microcontroller (which is the same as the one used on an Arduino Uno) that you can program yourself.
BTW, did you know that November 11th is Singles’ Day in China? That it is Armistice Day in many European countries to commemorate the victims of World War I? That the Carnival season begins? That Demi Moore was born on 11/11? Do you need any more reasons to power up our 11-11-almost-11 LED circle
