1.Learning goals

The children can use a fan and its drive board and a micro:bit to make a small fan. When the A key is pressed, the fan turns, and the fan icon is on the dot matrix; when the B key is pressed, the fan stops turning, and the dot matrix is still showing a love. Children, this class must have adults around. When fans turn, they can't touch fans.

2.Preparation

Hardware:

  • 1 X Micro: bit Board
  • 1 X Micro USB Cable
  • 1 X Micro:bit breakout
  • 5 X Male to male cable
  • 1 X 830 holes breadboard
  • 1 X fan
  • 1 X ULN2003 driver board

 

Then the micro:bit is connected to the computer through USB, and the computer will pop up a U disk and click the URL in the U disk to enter the programming interface. Input this URL https://github.com/lzty634158/yahboom_mbit_en to get the package.
