The rainbow LED changes in accordance with the color of the cards and it executes the defined functions accordingly(move forward,;change the color of the headlights at random; obstacles avoidance; line-following)

Let’s use micro:bit to make a game of avoiding bricks. It can control the spots by gravity to avoid the falling bricks. Once it touches the bricks, the game ends. Let's see how it works:

The Christmas day is coming now! Let’s make a candies ejector to send out candies to Children.

Now I’m going to use micro:bit to make a breathing light. The breathing light means that the light changes gradually from bright to dark under the control of a micro:bit, and it feels like a person is breathing. It is widely used in mobile phones and has become one of the selling points of new mobile phones of major brands, acting as a notification reminder. First look at the effect:

Cats are animals with strange tempers sometimes, they will run away from you while you want to touch them; and when you want to focus on your work, they just keep annoying you. Thus, I’m gonna make an automatic device with the help of the laser that is able to tease the cats.

It might be awkward for us to directly say “I love you” to our loved ones in Chinese culture, if you have a micro:bit in hand, how could we use it to express our love? Now I am gonna make a heart-beating icon in the micro:bit display as below:

I’d love to put this device in my box containing lots of bricks to get my cat away from it as it always carries them in its mouth or plays inside the box, I hope to scare the cat away with the sound and LED bricks.

It is set for people who are too busy to water the plants. With the help of the temperature and moisture sensor, the soil moisture sensor and the light sensor, it’s able to detect the status of the plants and have the data displayed on the OLED dispay, also, the LED would light on for reminding us of watering the plants.

Build a car with the bricks and drive it as the indicator says with the AI Lens.

Maybe many people have heard of arduino more than micro:bit, and even have used Arduino. Before the coming out of micro:bit, Arduino was hailed as the most suitable circuit board for maker education, because we can see that many manufacturers of maker products used Arduino UNO's 328P ...
