Over the summer of 2017, I decided to take summer classes for the first time in my life. My department, HCDE was offering a pilot course for Internet of Things - basically a course with a lot of creative product design with some great software/hardware introductions.
For the midterm I took on an idea that I have had for a while - basically, a light switch panel that has a responsive RGB LED that indicates the weather based on your location. I utilized two different ESP8266 Feather Huzzah's to make the communication happen through MQTT and a little bit on Node Red. One ESP was dedicated to the sensors and *sending* data to MQTT - I used a motion sensor and a light sensor. The motion sensor worked as an on/off switch: no motion for 10 minutes = no light, unless the light sensor was reading units less than 20, then the LED turns red and stays on.
I used Node Red's dashboard function while testing out some of the intitial phases of the project but moved away from it in the final stages of the project.

*the buttons represented the switch - I took the panel off my wall and really couldn't take the switch as well.
