Homebrewing bubble counter

Bubble counter for monitoring fermentation process. I cracked open [one of these](https://www.aliexpress.com/item/33004482943.html?spm=a2g0s.9042311.0.0.27424c4dsiZIjQ) to make them wider. Afterwards just place it in this rig connect to esp8266 and you should be ready to go. If anyone interested I can share code.

Idea came from [this guy](https://www.programmingelectronics.com/homebrewing-arduino-student-project/)
