Display Twitter messages on a string of Christmas lights (inspired by that one Stranger Things scene)
- HiLetGo ESP8266
- A strand/sequence of (at least) 26 WS2812 LEDs (search for "addressable Christmas lights", make certain they are WS2812 compatible)
- Wallpaper and black paint
Hang a strand of addressable LEDs, starting at the letter Z snaking up through I to Q, then up to H through A. Assuming a strand of exactly 26 pixels, see the Pixel Map for which pixel index corresponds to which letter.
Create the following file with your secret WiFi credentials and Twitter handle:
const char *SSID = "ithurtswhenip";
const char *PASSWORD = "hunter";
String PATH = "TwitterNameHere";In firmware/firmware.ino, set *SSID *PASSWORD to the SSID and password of your WiFi network.
If your light strand doesn't correspond exactly to each letter, e.g. you have a strand of 50 lights with some being unused between each letter, set PRECISE to false and change the values in the method lightPreciseLetter to match your lights' positions.
Deploy this application to Heroku, or feel free to use strtw.herokuapp.com. I'll keep it freely available as long as the rate limit doesn't get hit.
- Lights stopping after a period of time (20-40min): This could be due to a memory leak in 2.4.x. Try installing ESP8266 version 2.3.0 within the Board Manager.
