eyeblink | addressable LED animation for NeoPixels and the Particle | Augmented Reality library

I have created multiple html5 canvas using instantiation mode in P5JS. I am using Neurosky mindwave EEG sensor to activate and deactivate canvas one by one. Neurosky mindwave EEG sensor can detect user's eye blink which I am using as input. When user blinks, it should activate one canvas and deactivate another canvas and vice-versa.I am using Neurosky mindwave EEG sensor to activate and deactivate canvas one by one.

Just to check if my code logic works, I used mouse pressed input to switch between the canvas and it worked perfectly. But, when I used it with the sensor it didn't work.

What I did - I have created multiple HTML5 canvas using instantiation mode in P5JS. I have used node-neurosky node module to capture the eyeblink data from the sensor. Node Module

What worked - When I launch the app it takes the eye blink as input for the first time and activate the another canvas but when I blink again it doesn't deactivate the current canvas and activate another canvas. I have tried printing flags to check the code and it is doing fine. Eyeblink gets detected every time when I blink but it doesn't switch the canvas.

What didn't work - When I tried to use eye blink strength directly into the sketch.js it didn't work then I created another boolean variable eyeclick which also didn't work.
