How to start?

Post by Adrianoecker »

Hello to all.
I want to create a similar project to this link below.
https://vimeo.com/87240498
Controlled by Softwar Lightjams.
But I do not know which unit should I buy Adafruit.
And what would be the necessary link to the video as everything works.
Thank you ...

[Moved to the "Glowy Things" forum]

I'd start by looking at our NeoPixel products. These are based on the WS2812 - (successor to the WS2811) and are available in many forms.

These can be controlled by an inexpensive processor such as the Gemma or Trinket

ok, thank you.

I wonder how I can control WS2812 with Adafruit Trinket - Mini?
Or not and the logic of thought?

There are various tutorials out there covering neopixels and Trinket/Gemma on the Adafruit learning site (if you search for neopixel, you will see quite a few). The place you should start is with the uber guide: https://learn.adafruit.com/adafruit-neopixel-uberguide.

On the Trinket (and Gemma), you are limited by the amount of memory in the processor. Given you have only 512 bytes of SRAM in those processors, I suspect anything with more than 100 neopixels (each neopixel takes 3 bytes of sram) will probably be problematical on the Trinket. If you have the Trinket, I would say get a few neopixels to play with, and then if you need to scale up, you might need to scale up your processor. If you haven't bought the trinket yet, you might start with an Uno or something similar to avoid having to switch machines mid-course.

If you are going to be dealing with a large scale display with several hundreds of neopixels, you will probably need to go up to the Teensy 3.1 (with the octows2811 shield meant for handling large number of neopixels) or the Fadecandy.

Even if you are only dealing with a hundred or so neopixels, you probably need to start paying attention to how you power them up, and the best practices in the uber guide.
