It's very personal to me :D
This is my one of the favorite project ever that makes me glad whenever I think of it. It is one of the interesting and complex project in which you have to implement :- ESP32 CIRCUITALS, CODE MAPPING AND CODE REFRAMING, KEY MAPPING, VALUE INTERPRETING, and USB DEBUGGING..... All of these into one project . It took me over 5 days to complete this project because not all time youtube works.. sometimes you have to do your own and i too did learn all this for completion of my project
I am basically building a simple alarm based on seeed esp32 c3 and it is dor training purpose. In future , I can do many stuffs like this
