ScratchGPIO can control neopixels but your first have to install the Pimoroni UnicornHAT software.
Once you’ve done that, you can connect a set of neopixels up to the Pi 5V,Gnd and Pin12 and control them from Scratch
How to use
create a variable called AddOn and then make a little script
OnGreenFlag
..set AddOn to Neopixels (you can add a number on the end to tell if max num of neopixels – default is 64)
You can the nuse the following syntax
broadcast pixel 1 red (will turn 1st pixel to red) (valid colors are red/green/blue/magenta/cyan/yellow/white/off)
broadcast AllOff (turn them all off)
broadcast AllOn Blue (turn all pixels Blue)
Note change to pixelson/off in Scratchgpio8
