E-Textile Christmas Tree

This project involves the creation of an e-textile Christmas tree made out of felt and controlled by a BBC micro:bit. It enables learners to practice their iterative design, electronics and programming skills.

Resources Required:

  • 6 x 3mm LEDs (2 colours, 3 of each)
  • Felt (3 different shades of green)
  • Needle nose pliers
  • 3v coin cell holder with switch
  • 3D printed micro:bit holder (details can be found here)
  • Conductive thread
  • Sewing needles
  • Sewing thread
  • 3v coin cell
  • 2 x crocodile clips (for testing)

Optional:

  • Embroidery thread
  • Assorted buttons

Note: If you are unable to obtain/3D print the micro:bit holder you can use crocodile clips to connect to the micro:bit instead.

The following handout provides suggested steps in the creation of the project:

You will also need the shape template:

Ideas for Extending the Project

  • Sew a loop of ribbon to the top to allow it to be hung up.
  • Create a cardboard stand that could be slotted into the bottom of the tree to make it stand up.
  • Add a felt star to the top of the tree.
  • Create different light patterns that can be activated by pressing the micro:bit buttons.
