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

It's fairly easy to hook up, let me know if you need anymore help.

Are Neopixels a brand new product? I'd love to use them too. Thanks for the great work so far, guys. Has anyone made an LED rope work yet? If so, a video zooming in on the wiring and some code would be awesome.

Do we need to program the Arduino AND the EZB V4 to control the lights properly? Also, what are you guys doing about isolating power? I have a 12V servo, eighteen 7.5V servos, four 6V servos and now I need the lights and Arduino, which I guess are both 5V. My 12V46A power supply can have a voltage reducer attached to it, or I could use separate power supplies for everything....

Anyway, if you figure it out, a video with all the connections would be awesome :)

Dont know about the Neopixels but... if your power supply has the capacity there is little reason why you can't use regulators to add more devices of different voltages. Just leave some overhead voltage when you're done adding. The only issue you may run into is electronic noise from devices effecting each other. You'll see this in twitching servos, weird noise in audio. Electronic noise travels on the neutralsite and ground. There's a few fixes for this issue. One would be to run the noise makers off a different power supply and don't have any grounds tied between the two.

Thanks for the advice. What do other people use for various voltages?

It totally depends on the device needing the voltage. Common voltags are 3.3, 5, 4.7, 6, 7, 12. You need to be equally conserned with how many amps your connected devices will draw. Add up all the amps all your connected deviced are rated for combined. That number can't be more than your regulators or power supply is rated for. Leave your self a little overhead just in case.
