users can enter text up to 250 letters and it will decode it into morse code and play it on a buzzer. Users can choose the speed the morse code is being played.
It is a must to look at this documentation for WIFI in general https://esp32.implrust.com/wifi/web-server/wifi.html
To check if the morse code actually works I highly recommend https://morsecode.world/international/decoder/audio-decoder-adaptive.html site.
