1.Learning goals

Children can use a ultrasonic module and a micro:bit to make a distance detector to see how far you are from me.The jumper wire cap of the power supply module connects 5V to OFF to output 5V voltage.

2.Preparation

Hardware:

●  1 X Micro: bit Board

●  1 X Micro USB Cable

●  1 X Micro:bit breakout

●  1 X Male to male cable

●  4 X Female to male cable

●  1 X 830 holes breadboard

●  1 X Ultrasonic sensor

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.

3.Connection

Connection line according to the upper drawing.

Note: Ultrasonic sensor must work at 5V, and micro:bit GND must be connected to GND of ultrasonic sensor.
