Shipped this project!
The thing i built a countdown timer prop bomb. It counts down displays it on a screen as well as LED’s blinking and a speaker playing (optionally you can use the relay which triggers when the timer hits 0). The hardest part was to get the relay to work since i used a WEMOS d1 mini (esp8266) and it didn’t quite have enough power to use the relay and all the other digital ports. I fixed this by using an external power supply for the relay, i also added a manual trigger, but removed it before the completion of the project.
Wokwi dev log, added Wokwi circut. Had to change some parts since they werent on Wokwi and the code is also adjusted. I couldn’t get it to work, but all functionality is shown in the video below.

Been testing for hours, but got nothing out of it. Found that hardware change was they key. Changed the 5v and gnd and then it worked.

I’ve just made the code a bit more stylish, added a readme and tested some hardware especially the relay.
