Walking in a Winter Wonderland

A step back in time, to your childhood. Today, we’re making play dough! But conductive dough, with 15 LEDs, following the recipe from Technology Will Save Us.

You’ll need:

  • 15 mixed LEDs
  • Wires
  • Arduino UNO

For the dough:

  • Water
  • Flour
  • Salt
  • Lemon juice
  • Vegetable oil

1) Making the dough
The recipe for the dough is available on the TWUS website. Following those instructions, make some conductive dough (I’ll keep it white, to get a snowy feeling). I will use cardboard to keep the pieces apart, instead of insulating dough.

Leave the dough to cool down before modelling it. Once it’s cold enough, start by testing it with 1 LED:

Now, let’s try and make a snowman.

Prepare the shape of your snowman, then cut it in half, placing the cardboard between the two parts so that they don’t touch each other and create a short circuit.

Plug a few LEDs into it, and then wire it to your Arduino : The code is simple, declare the LED pin, set its mode to OUTPUT and its value to HIGH, and you’ve got a lit up snowman! (You could even make it blink…)

2) Winter wonderland
You can now make more characters and objects, such as an igloo, a tree, some stars… It’s up to you!
