EmotivBCI - Mental Commands Yes/No

README.md

Mental Commands yes/no example:

This flow allows you to use Mental Commands to express YES or NO as text and voice. After deploying the flow, open http://127.0.0.1:1880/ui on a new web browser tab to view the result.

How to import example:

To import this example to Node-RED:

1. Start Node-RED in your Terminal or cmd window
2. On your web-browser, go to http://127.0.0.1:1880 to open Node-RED
3. On the top-right screen, go to Menu/Import/Clipboard and paste the contents of the JSON file below in "example directory".
4. This examples require:
   On cmd/terminal, go to ~/.node-red and enter these commands (local install):
   a. EmotivBCI Node-RED Toolbox: npm install node-red-contrib-emotiv-emotiv-bci
   b. Node-RED dashboard: npm install node-red-dashboard
   

Since all BCI Node-Red flows and other Emotiv applications share one instance of Cortex Service, so you should only run/deploy one flow at a time.
