Summary
In this chapter, we learned how to work with the limited filesystem of Micro:bit powered by MicroPython. We learned how to create, delete, read, and alter the contents of files on Micro:bit using MicroPython programs. We also learned how to work with the OS module in MicroPython and the MicroFS module of Python on our computer. We will use this knowledge in the upcoming chapters of the book when we need to install and work with external libraries for external hardware modules.
In the next chapter, we will explore the concepts of analog input and pulse-width modulation (PWM). Using these concepts, we will program a potentiometer, photoresistor, servo motor, red, blue, and green light-emitting diode (RGB LED), and joystick with microPython on Micro:bit.
