Code for Raspberry Pi project to sync LED lights to real-time weather data, pulled from the WeatherUnlocked api every 5s (adjustable).

WIRING CONFIGURATION:
Note: It is possible to use your own custom pin out number, but do be sure to update the .env file to reflect these changes.
Sign up for the free WeatherUnlocked api and receive your app key and app id.
Install node.js and npm on your pi. Verify installed correctly with:
node -v
npm -v
Run on your local proj directory, run:
npm install
Fill out the appropriate .env file values.
Access your pi's unix/bash shell via ssh or directly.
Run the pi config script on your pi while in your project's directory to install pigpiod:
chmod u+x pi-config.sh
./pi-config.sh
Boot pigpiod (if you ever run into permission or 'already running' errors for setting pin values, run this script to reboot pigpiod):
chmod u+x boot_pigpiod.sh
./boot_pigpiod.sh
To test, I have included a script to set the lights to a desired RGB value. Run this script with ./set_lights.sh <red_rgb_val> <green_rgb_val> <blue_rgv_val>. Ex) to test the lights, set them to all red:
chmod u+x set_lights.sh
./set_lights 255 0 0
Given all installation is correct, then began the LED weather sync service with:
chmod u+x WEATHER_LED_SYNC_SERVICE.sh
./WEATHER_LED_SYNC_SERVICE.sh
OR the tides LED sync service with:
chmod u+x TIDES_LED_SYNC_SERVICE.sh
./TIDES_LED_SYNC_SERVICE.sh
Feel free to mess with some other scripts in the repo. For example, for random strobe, run:
chmod u+x disco_lights.sh
./disco_lights.sh
To set a one time random rgb color:
chmod u+x set_random.sh
./set_random.sh
For police sirens:
chmod u+x police_sirens.sh
./police_sirens.sh
Shut lights off (all values to 0)
chmod u+x lights_off.sh
./lights_off.sh
You can use command node rand-1to255.js to generate a single random value [0,255] or node random-rbg.js for a full random rgb value. Pipe or input the output to your bash script appropriately.
I have configured my pi to run the WEATHER_LED_SYNC_SERVICE.sh on startup which has proved to work very well.
