Snips Skill NeoPixel

Requirements

Arduino Board
NeoPixel Ring 24

Configuration

We made a library to use the Arduino board as an actuator of the Raspberry Pi. We would recommend you to use an Arduino Micro as it is more than enough for the purpose. Here are the steps to configure it:

You install the Arduino IDE (here) it will help you upload the code into the Arduino.
Clone/Download the Neopixel Ring library into the Arduino library folder.

*/documents/arduino/libraries

Clone/Download our Snips_lights library into the same Arduino library folder

Note: if you have Arduino running, you would need to restart it for the libraries to load and show under the Examples menu.

Open the Snips_lights library example called home:

Plug your Arduino board
Pick your Arduino board under Tools > Board and upload the example via the Arduino IDE.

Mount

In order to see the NeoPixel reacting to voice you will need to solder it with the Arduino board first. Here we show you with an Arduino Micro:

First you need to solder the Neopixel ring and the Arduino Micro. Start to solder red and black wire to the 5V and Gnd pins of the Neopixel Ring then solder a color wire to Data pin.

Then solder the red and black wire to the 5V and GND of the Arduino Micro, and the Data on pin 6.

Snips Manager

It is recommended that you use this skill with the Snips Manager. Simply add the following section to your Snipsfile:

skills:
  - package_name: snipsneopixel
    pip: https://github.com/snipsco/snips-skill-neopixel
    params:
      arduino_port: <ARDUINO_PORT>
    dialogue_events:
      - event: session_started
        action: |
          {%
          print("->>>> Session started <<<<-")
          snips.skill.listening()
          %}
      - event: session_ended
        action: |
          {%
          print("->>>> Session started <<<<-")
          snips.skill.stand_by()
          %}

On your Pi the <ARDUINO_PORT> should be /dev/ttyACM0 but we can double check the connection as follows:

Plug Arduino to Raspberry Pi using the proper USB cable
Run ls /dev/tty* on your Raspberry Pi terminal. The result should be content /dev/ttyACM0 which will mean that you are good.

Usage

You can use the NeoPixel skill as follows:

from snipsneopixel.snipsneopixel import SnipsNeopixel

neopixel = SnipsNeopixel(<ARDUINO_PORT>)
neopixel.loading()
