I put the LEDs in the mold and soldered the ground together, then added positive rails for each color LED. Then I took it out of the mold and soldered it to the circuit board.
I also had to fix a couple of problems with my code (the pinout for the NodeMCU is confusing...)
Last, I painted over one of the on-board LEDs so that it wouldn't be so bright and distracting.
This was a fun little project that helped me to learn about how to use WiFi with Arduino boards.
Hope you liked my idea!

I set up an Adafruit IO feed and connected it to Weather Underground through IFTTT to send the weather every morning at 6:00 AM.
I connected the circuit to the internet and tested it with three LEDs to show basic weather (white=cloudy, yellow=sunny, blue=showers/rainy). I also 3D printed a mold/jig to hold the LEDs while soldering.
