Wordle Like Light Up Badge

Wordle is a popular word game where you can share your results in the form of a graphic block chart. It shows your attempts at guessing the unknown word and gives you bragging rights in having determined that word in the least tries.

This is a badge that you can wear to display the results of the game.

This is just a prototype to create a light up badge to display Wordle results so it is only programmed to simulate gameplay for the animated lights. Further work is needed to really integrate this with the actual game or get results from a database.

I did not have a 5x6 LED matrix to use for the display lights so I gathered up all of my odd lengths of neopixel strips to wire up into matrix(really just one long strip with wires to connect the strip cut into segments for 6 rows. Each segment actually has more than 5 neopixels so that there would be spares to cut off if the soldering damaged the strip(soldering to the cut flexible neopixel strip requires more skill-solder pads are smaller and the plastic strip and tiny parts on there can be damaged with excessive heat or flexing). Test everything before using hot glue to add strain relief to the wires attached to the neopixel strip.

Neopixels are individually addressable LEDs so it requires a microcontroller to send out commands on what color to light up. A small battery pack makes everything portable.

I printed out a grid that I covered with clear packaging tape to give it some durability. It will serve to diffuse the neopixels a bit.

You can even create a 3D printed or lasercut badge to house or mount the electronics.

The current light animation that is running simulates Wordle.

5 letters are input - 5 bright white lights appear.

You then get the results back.

If the letter is used in the unknown word but is not in the correct position, a yellow light will appear.

If the letter is used in the unknown word and is in the correct postion, a green light will appear.

If the letter is not used in the unknown word, that space will dim out, looking gray.

Each row for 6 attempts is run.

When all the correct letters in the correct positions are determined, the entire row is green and will flash.

Further coding is to pass the correct green lights that appear on one row to the next.

So, you can use this as a start to simulate the full gameplay of Wordle, integrate with machine learning or artificial intelligence rules, store multiple results and analysis...

And light up those excess neopixels into a rainbow trail like Nyan Cat...the more you know...
