Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The board module contains definitions of the pins and peripherals specific to the board."

A block of code is set as follows:

from machine import Pin
import utime
led = Pin(25, Pin.OUT)
while True:

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

while True:
    led.toggle()
    utime.sleep(1)

Any command-line input or output is written as follows:

>>> print("Hello World")

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: "An impulse can be created from the Create impulse tab on the left."
