We've made more than 100 kinds of electronic modules into Crowtail modules. They include a
variety of sensors, displays, inputs and outputs modules, communication types include I2C,
UART, digital or analog, which aim to provide more options to fully meet all needs for your
electronic projects! All modules can be used by simply connecting them to the Crowtail- Base
shield for Micro:bit with Crowtail cable, which is a huge improvement over the previously
troublesome jumper connections.
Crowtail – Modules
Electric lights are ubiquitous in our daily life which we can't even leave. It was the invention of
the electric light that marked the human society's entry into the electric era, and made people
welcome the light in the dark night. Here, we will learn how to use the LED and control it’s on
and off.
Learn how the LED work and use it to make a blinking light.
Learn how to run the code forever.
Learn how to output logic high and low signals.
Learn how to pause the code.

LED is the best choice to help you learn I/O pins. What you need to do
is connecting the LED module to the port of the base shield, then
download the program to the Micro:bit. Besides the very basic usage,
you can make the LED blink with the frequency you want, or adjust
the brightness with PWM. Actually, LED is the most popular used for
human interface.

Note:
When you connect a high-power device, such as a motor, you need to connect a 12V
power supply to the board.
