Just a fun side electronic project, an Automatic Fishing Reel Spooler(not for when you are on the lake, but before when you are putting line on the fishing reel).

Improvements and fixes

For the fishing line distance measuring, i was planning on having a measuring wheel with magnets glued to them, and when fishing line was reeled on to the new fishing reel it would spin and activate a hall sensor and for each pulse a distance would be added to the counting, issue is when i had printed the measuring wheel and then glued magnets, i realised that the hall sensor only activated on one polarity, which i didn't know. To not have this issue blocking the development of the webserver i instead removed and put that part of the project in pause for later testing and adding in later. So in the future i want the user to be able to set a X amount of meters of line to be only feed to the reel via the webserver interface.
For now it uses TCP communication, issue is that since status update is wanted on the webserver to know the device position and state, TCP is a bit blocking on the ESP32, meaning i would prefer to maybe use UDP or some other communcation type to not block the device but to know the status of the device in the future.
Could make the webserver interface better looking and user friendly, for now it's in the most basic form, issue i wanted to reduce file size since i had limited 400kb memory on the ESP32-C3
Instead of hosting a webserver i could develop a desktop .NET program that talks to the ESP32-C3 devices
