Hello, when we hold birthday parties, the lighting candles come to our mind for best wishes! If we have a micro:bit by hand, is that possible to make an electronic candle device with it? Here comes the case of blowing off the candle “fires” by sound.
Through the introduction of the turtle extension library in the previous article, we have learned the basic concepts of turtle graphics. In this article, let’s learn how to draw a helix with micro:bit. Press the button A to draw a helix on the LED screen, and press button B to eliminate the helix as the same way:
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:
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:
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.
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 ...
