Outcome

A weather indicator: Use a DC motor fan with the neopixel LEDs to be a cue when the weather is not good. Video

Move up Delete Move down

Process

I attempted to build a weather indicator that uses wind force to blow up a soft fabric along with LED lights. Yet the fan was not powered enough to blow up the plastic bag so it didn't show the movement prominently.

Reflection

I tried to make the fan work and the LED light up at the same time. Yet, it seems there were some problems with the for statement embedded in another for statement. I assume it causes the for loop for the LED to complete first, and then the for loop for the fan starts.
