Creating and Editing Code

One of the best things about CircuitPython is how simple it is to get code up and running. In this section, we're going to

cover how to create and edit your first CircuitPython program.

To create and edit code, all you'll need is an editor. There are many options. We strongly recommend using Mu! It's

designed for CircuitPython, and it's really simple and easy to use, with a built in serial console!

If you don't or can't use Mu, there are basic text editors built into every operating system such as Notepad on Windows,

TextEdit on Mac, and gedit on Linux. However, many of these editors don't write back changes immediately to files that

you edit. That can cause problems when using CircuitPython. See the

If you want to skip that section for now, make sure you do "Eject" or "Safe Remove" on Windows or "sync" on Linux

after writing a file if you aren't using Mu. (This is not a problem on MacOS.)

Copy and paste the following code into your editor:

import board

import digitalio

import time

led = digitalio.DigitalInOut(board.D13)

led.direction = digitalio.Direction.OUTPUT

while True:

led.value = True

time.sleep(0.5)

led.value = False

time.sleep(0.5)
