MicroPython is a reimplementation of the Python programming language that targets
microcontrollers and embedded systems.
Microcontrollers are computers shrunk onto a single, very small chip. Embedded systems
are computers that function within a larger mechanical or electrical system.
Embedded systems often use microcontrollers.
This book introduces, explores, and explains MicroPython through four typical yet
different devices,1 all of which have a microcontroller at their core.
Such devices are very different to other sorts of computer. Most computers contain
lots of parts: memory, storage, and processing are physically separate components
containing various specialist chips. They may also contain additional parts for sound,
graphics, and networking capabilities. Such computers are significantly more powerful
than the resource-constrained, microcontroller-based devices used in this book.
