可寻址LED#

初始化 AddressableLed 类 #

使用以下构造函数创建 AddressableLed：

AddressableLed(port)

此构造函数使用一个参数：

范围	描述
`port`	The 3-Wire Port that the AddressableLed is connected to, whether it’s a port on the `Brain`, or a `3-Wire Expander`.

A Brain or 3-Wire Expander must be created first before they can be used to create an object with the AddressableLed Class constructor.

# Create the Brain.
brain = Brain()
# Construct an AddressableLed "addled" with the
# AddressableLed class.
addled = AddressableLed(brain.three_wire_port.a)

This addled object will be used in all subsequent examples throughout this API documentation when referring to Accelerometer class methods.
