Micro:bit Math Project

This project uses four micro:bits to set up a math equation for the user to calculate and then enter into the primary micro:bit to check.

The project is very simple on the requirements:

• Four micro:bits
• Optional micro:bit mounting location

With the plan in mind - there is one primary micro:bit and three secondary micro:bits. The primary micro:bit does all of the control, sending of the numbers and math. The three secondary micro:bits are only for the display of two numbers and the math symbol.

The main breakdown of the code is as follows:

1. Starting the program with the two numbers, symbol, state, guess and answer variables
2. The program starts waiting for the user to activate the math question.
3. By pressing A and B together it will go into the next part - randomly picking of the numbers and math symbol and then sending those values to the secondary micro:bits
4. The secondary micro:bits display the values and symbol and wait until the user pick the correct answer, using A and B to raise and lower their guess.
5. Use A and B together to 'lock in' their answer.

Code is included in the next step but users are invite to try it out themselves.

The code for the four micro:bits are included here for your pleasure.
