Outcome

Move up Delete Move down

Outcome

Using Neopixel, along with its electrical connection & IDE interface, is explored in this lab.
Connecting online apps and Particle IDE through IFTTT is also a major objective.
The setup is shown here while multiple functionality videos are detailed in the process below.

Move up Delete Move down

Process

Different exercises are done to show different capabilities:
Ex 1. Turning Neopixel on
Ex 2. Turning Neopixel on & cycle through different colors
Ex 3. Turning Neopixel on & off one pixel at a time
Ex 4. Inputting RGB value the web interface
Final. Turning Neopixel on 15 minutes before calendar meeting starts
