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.
- 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)
- 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.
