sensor.startSchedule() # No matter how many interrupt threads you have, you only need execute this line once The default Chinese character font size is size 1, which is 12*12 pixels. The font size increases with the increase of ext, font size=12*ext.

It can be used when it is set to the analog output mode (mode = PWM). Output 0~1023, and decompose 0~3.3V into 1024 ranges of voltage. Parameter: b. Use a text editor (VS Code recommended) to open main.py and then write a program to show a line of welcoming strings on the screen and save the program.First we need to be sure that if there's no special setting, Meowbit would run the main.py file once being powered. Thus we only need to put a mian.py program in the SD card. (When the SD card is not detected, the PYBFLASH drive letter of Meowbit is the internal Flash with only 2M storage. When an SD card is inserted and detected, the storage becomes larger.) Sample Program B 📋: The buzzer sounds when button A is pressed, it mutes when the button is released SD Card Slot (File storage in MicroPython mode, specialized Meow SD Bluetooth module extension in Arcade mode) Retro-styled games in a board smaller than your palm - that’s what the Kittenbot Meowbit is. Made specifically for the Microsoft make:code Arcade platform, this console allows anyone - from kids to adults - to easily enjoy retro games wherever they are, regardless of prior experience in both coding and game design.

buzzer.melody(CORRECT) # when playing this melody, press A to execute the operation of stop the buzzer to stop the melody Show Chinese characters (including English letters and numbers, but using screen.text() will have a better effect if showing non-Chinese strings). Parameter: The arrows point at the positive direction of the corresponding axial speed （the screen facing direction) The coordinates are in the upper left corner of the first character, the default is (0, 0) if it is not set

It can be used when it is set to the analog output mode (mode = PWM). Output the PWM duty cycle. It normally is used for controlling servos. The duty cycle in a cycle is calculated to control the angle accurately. Parameter: TFT Color Display, Dual LEDs, Light Sensor, Temperature Sensor, 6 Programmable Buttons, Passive Buzzer, SD Card Slot, Gyroscope, Expansion Pins, JacDac Port The Meowbit is a card-sized graphical retro game computer with allows you coding with Makecode arcade and Python. In other words, it can combines game programming, design while presenting learners the opportunity to learn mainstream programming languages like micropython. The Meowbit is a card-sized graphical programming video game console designed for kids of all ages. color: R, G, and B stand for red, green, and blue respectively. The range is 0~255, which is the standard RGB color value. If left blank, the default is color white, and the brightness value is 255. MicroPython supports standard Python file modules. For example, we can use built-in functions like open().

os.remove('xx') # xx is the file that exists in the current directory, needs to have a file extension like .txt

Conclusion

The buzzer stops playing. Can be placed in the button interrupt to stop the melody from playing; can also be combined with melody playing to create the effect that it sounds when the button is pressed, and mute when the button is released.
