Pwm#

Initializing the Pwm Class #

A Pwm Output is created by using the following constructor:

Pwm(port)

This constructor uses one parameter:

Parameter	Description
`port`	The 3-Wire Port to use for the Pwm Output, 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 Pwm Class constructor.

# Create the Brain.
brain = Brain()
# Construct a Pwm Output "pwm" with the Pwm class.
pwm = Pwm(brain.three_wire_port.a)

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

The state(value, units) method sets the state of the PWM.

Parameters	Description
value	The new value to set for PWM output, from -100 to +100 percent.
units	Optional. The only valid unit for pwm output is `PERCENT`.

Returns: None.

# Set PWM output to 50%.
pwm.state(50)
