Introduction
Instructions: Complete each step below to create a sketch of your Micro: bit expansion board prototype and put together a budget for prototyping materials!
Review: What was your problem statement?
Write your problem statement from Mission 1 below. It should be in the form of
“I need to create a ___ using the Micro: bit expansion board so
that ____ can. ____.”
What solution did you ideate?
In the space below, answer these two questions:
A. What was the winning “idea” from your brainstorming session in this
lesson?
B. How does this idea solve your user’s problem?
Sketch your idea!
Draw a rough sketch of your wearable idea below. (You can also draw your idea on a separate piece of paper and upload a photo of your drawing).
Consider the following:
- Where will the Micro: bit go?
- What prototyping materials will you use?
- What are your inputs and outputs?
- How will you wire your design?
- Will your design have case to house the electronics?

Let’s look at an example of a budget
In step 5, you will decide what materials you need to build your prototype. The total cost of your materials must not add up to more than 500 VilCoins!
Here is an example of a budget from a similar student project. Here, students had a budget of 1,000 Pesos to build a flashlight out of household items.
Create your own budget!
Fill in the table below with the quantity and cost of the materials you need to build your prototype! Make sure your total cost is less than 500 VilCoins!
Here is an example of a budget for this project (yours can be completely different!)
Not sure what some of the components do (like the soil moisture probe, or RGB LED)? Click here for a complete guide on the sensors available.

Total Cost
Answer the following questions:
A. What was your total cost?
B. Are you under the 500 Vicon budget?
C. Did you have to make any changes to your design based on the budget?
Optional Challenge
Do you have another idea for a Micro: bit prototype that could solve this problem? If so, draw it in the space below. If your original design doesn’t work out, you can always use this one as a backup.
