pwmd

pwmd exposes the Linux' sysfs PWM interface to DBUS.

Why

PWM controllers are often used for LEDs. Playing around with LEDs is fun and it's also super easy to control them, thanks to a simple sysfs based API the Linux kernel exposes. Only drawback: your hacky script needs root privileges to use it.

With pwmd you can use DBUS to control LEDs without root privileges. Under the hood, pwmd uses the sysfs API - it exposes this part of sysfs to user-space via DBUS, without running the risk of scripts causing mayhem to other parts of sysfs.

Getting started
