Move up Delete Move down

Reflection

Wiring process was fairly simple. However, realizing ambient effect through code was tricky. Through this project, I could become more familiar with coding in the Particle platform and using physical computing languages. Also, using the Particle function and Serial Monitor made the process more responsive.

Image of console monitor. I like the pattern it generates.

Call result from the IFTTT.
