Χαρακτηριστικά

PiGlow is a spiral nebula of 18 coloured, individually-controllable LEDs for your Raspberry Pi. Use it for all sorts of things. And, of course, it fits inside a Pibow case!

This diminutive board is compatible with all 40-pin Raspberry Pi models, and can be controlled really simply with our PiGlow Python library.

Use PiGlow for mood lighting / ambience, monitoring the status of your system, scripts, or daemons, Twitter mentions or emails, VESA-mounted behind your monitor or TV, or a zillion other things!

There are tons of things you can do with it:

Mood lighting / ambience
Showing current system load
Notify you of events like mentions in tweets or incoming e-mail
Feedback the status of scripts/daemons running on your Pi
Works great when VESA mounted to provide a cast against a wall
...and pretty much anything else you can think of!

Software

Our PiGlow Python library makes controlling PiGlow a piece of cake. You can control the brightness of the different colour groups of LEDs, the arms of the nebula, or individual LEDs - flexible! There's also a handful of examples to show you what can be done.

ΣΗΜΕΙΩΣΕΙΣ

Photo-sensitivity warning: flashing, strobing, and patterns of lights may cause epileptic seizures. Always take care and immediately stop using if you feel unwell (dizziness, nausea, affected vision, eye twitching, disorientation).

18 coloured LEDs (3x each red, orange, yellow, green, blue, white)
Driven by the SN3218 8-bit, 18-channel PWM LED driver
Uses I2C (address 0x54)
PiGlow pinout
Compatible with all 40-pin header Raspberry Pi models
Python library
Comes fully assembled

This board uses the SN3218 8-bit 18-channel PWM chip to drive 18 surface mount LEDs. Communication is done via I2C over the GPIO header with a bus address of 0x54 (Python example code provided). Each LED can be set to a PWM value of between 0 and 255.

If you just want some Python code to start tinkering with please check out our GitHub repository which also includes the full datasheet for the IC used on PiGlow.
