Neopixels

I was wondering that it was possible to connect an neopixel ring(16) directly to the ez b4? If so, where do i connect the com port to ? tnx

Looks great! Can't wait to throw out the Uno I have running my Neo Pixel Ring.

Yes DJ, that looks exactly right. Thanks for the video:) The neopixels rope is sold at adafruit, right? The only problem is that they only seem to sell 1 metre lengths. I need at least 20 metres of LED rope for my project. Does anyone know if its available?

Man you will need a lot of amperage for that. I would recommend splitting the strands across many 5 volt power supplies.

Think about that each neopixel has 3 led's. And unlike the ez-robot RGB 8x8 or RGB Eyes, neo pixels are "always on". The ez-robot rgb 8x8 or rgb eyes uses a pulse width technique in which only 1 led is on at a time. Neopixels do not have that option.

So if there are 3 led's per neo pixel...and you have 2,000 neo pixels. That's actually 6,000 led's! EAK

I can tell you that the 8x8 display in my video has 64 neo pixels, which is 192 LEDs. At 150 brightness, it draws 1.6-1.7 amps!

Is this a future piece of hardware to be the bridge between the EZ-B and Adafruit Neopixel products...this would be very much appreciated!:)
