I purchased 4 meters of neopixel LEDs from adafruit. I was going to try to make my ambilight work on all HDMI devices but changed my mind. Can I use the adafruit neopixel LEDs with the data pin from the pi?
Can I use LEDs without a clock pin on a pi?

Thanks. Would I need to get a 3.3 to 5v converter?

You might need the level converter - in theory it's required but it works for some people.
Don't use those bidirectional level converters on Ebay.
Use some sort of 74hct chip (like the 74hct125)There are 2 led device drivers for the ws2812 leds. Pwm or spi.

I think I'll play it safe and get the adafruit brand one.
So all I need is to download the latest version of osmc and Hyperion and enable that in osmc. Then what is the default data pin on the pi for the output?

From memory - pwm is gpio 18
Spi is the SPI MOSI pin -
Thank you for the start!
