Hello world. I am here. Neo pixels blocky

[cadcygnus]

Ok, what I am trying to do is make Cylon eyes for my new robot. This is my first time here so be easy on me if I come off like a newbie.

I can get the blocks to work somewhat in Otto Blockly. But the problem is two-fold. I may not understand how the blocks should be stacked or used? The second problem is in understanding what parts of the code it writes are available for me to use. I can get the lights to work in the Arduino code. I just watched a video on how to add // these marks to the code to disable it. Here is something close to what I am shooting for. I also tried to add this code to a blocky in otto blockly that says add code here. It just went blank. I Love blockly and would greatly appreciate any help here. I am not a programmer I am a designer

`#include

ifdef AVR

include <avr/power.h>

endif

define PIN 6

// Parameter 1 = number of pixels in strip // Parameter 2 = Arduino pin number (most are valid) // Parameter 3 = pixel type flags, add together as needed: // NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs) // NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers) // NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products) // NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2) // NEO_RGBW Pixels are wired for RGBW bitstream (NeoPixel RGBW products) Adafruit_NeoPixel strip = Adafruit_NeoPixel(60, PIN, NEO_GRB + NEO_KHZ800);

// IMPORTANT: To reduce NeoPixel burnout risk, add 1000 uF capacitor across // pixel power leads, add 300 - 500 Ohm resistor on first pixel's data input // and minimize distance between Arduino and first pixel. Avoid connecting // on a live circuit...if you must, connect GND first.

Hi @cadcygnus this is great we will work on this for the next release, feel free to create other issues for more blocks request.

thanks

Hi @cadcygnus

We have fix the bug with neopixels it should work now in the latest version https://github.com/OttoDIY/blockly/releases/tag/v1.4.0

You can replicate that code by using one of the examples already that come with the software
