Sample Project Basic in Microbit

Show Icon

This project will use the show icon feature of Micro:bit to display various icons on the LED screen based on user input or certain conditions. This feature is very useful for creating interactive displays that are easy to understand, such as providing visual feedback, creating simple animations, or displaying device status. For example, you can display a smile icon if the device is in good condition or a heart icon when the user provides certain inputs such as pressing a button.

This project is suitable for beginners who want to understand how Micro:bit can respond to user input and display visual information. With a little creativity, this project can be expanded for various applications, such as simple games, weather indicators, or educational tools for children.

Projects to be created:

Mood Icon Display: Display smiley, sad, or heart face icons based on A, B, or A+B button input.

Block Code:

A button: Display smiley face.
B button: Show sad face.
A+B button: Show heart icon.
