Wait for the loading of the library. After the loading is successful, the following figure is shown:
Block code parsing
▶ 1: 
The module returns a value that is the numeric input value for P11. When the keyboard on the sheild is clicked, a low level is returned, indicating that the keyboard value on the sheild can be read.
Usage:
Press any keyboard on the sheild, the microbit dot matrix displays 0, otherwise displays 1.
Because the P11 is also mapped to the microbit Buttom B, the keyboard value of the sheild can also be read through the microbit Buttom B.
▶ 2: 
Read the keyboard values on the sheild.
Usage:
Press any key on the sheild, and the microbit dot matrix displays the key value.
Key value: U = 16, D = 8, L = 4, R = 2, OK = 1
▶ 3: 
Clear the display on the 4-digit nixtube of the sheild.
▶ 4: 
4-digit nixie tube displays numeric values.
Floating-point number display range: 0.0 to 999.9
Integer range: 0 to 9999
Usage:
▶ 5: 
Let one of the 4-digit nixie tubes display the number.
Parameter 1: 0 to 3, the position of the nixie tube to be lit.
Parameter 2: 0 to 15 (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F), characters to display.
Usage:
▶ 6: 
A display segment in a nixie tube.
▶ 8: 
Let one of the 4-digit nixie tubes display a segment.
Parameter 1: 0 to 3, the position of the nixie tube to be lit.
Parameter 2:
Usage:
The 4th digit tube display 2 segments.
▶ 9: 
Light an LED in the strip.
Parameter 1: 0 to 8, the position of the LED to be lit.
Parameter 2: 
(0: OFF, 1: ON)
Usage:
▶ 10: 
Controls the brightness of the RGB LED on the sheild.
Parameter 1: Red LED, green LED, blue LED.
Parameter 2: 0 to 1023, brightness.
▶ 11: 
Initial temperature and hygrometer.
▶ 12: 
Read the temperature and humidity values and verify that the values are correct. Execute this block at a frequency greater than or equal to 2 seconds.
▶ 13: 
Get the temperature or humidity value.
Usage:
▶ 14: 
When the ultrasonic module is connected to the Sensor interface of the sheild, the measurement distance value of the ultrasonic module can be read. The unit is centimeter.
Usage:
▶ 15: 
The value of the infrared receiver, microphone or sliding resistor on the sheild is read through the I2C protocol.
Usage:
Infrared receiver (NEC)
Microphone
Sliding resistor
▶ 16: 
When the fan module is connected to the fan port on the sheild, it is used to control the steering and speed of the fan module.
Parameter 1: CW = clockwise rotation.
Parameter 2: CCW = counterclockwise rotation.
▶ 17: 
Read the key value on the sheild, return 0 when the key is pressed, otherwise return 1. This key is connected to the P5 pin of the microbit.
▶ 18: 
Reads a byte of data from the memory of the sheild.
Parameter: 0 to 16, Address of the memory.
▶ 19: 
Write a byte of data to the memory of the sheild.
Parameter 1: 0 to 16, Address of the memory.
Parameter 2: 0 to 255, Data to be stored in memory.
Usage:
4 digit nixie tube display 255.
