sqlite_micro_logger_arduino VS TTS

There is a tiny SQLite library for Arduino that works with SD cards. I haven't used it myself, but it's probably easier to get an Arduino right now than it is to get a Pi, so it might be worth investigating.

Potentially interesting:

This is a heavily subsetted implementation of SQLite3 that can read/write databases (presumably on SD cards) from very small microcontrollers.

It presumably doesn't have the same ACID compliance properties, but with a single <1.5k source file, may represent a particularly efficient way to rapidly learn the intrinsics.

Now I'm thinking it could actually be interesting to see what drh thinks of this implementation (and any gotchas in it) because of its small size and accessibility.

Ive tried the same code which i use for the arduino but changed the gpio pin to 0(D3) on the node mcu. The code does get uploaded but didnt receive any audio output. What do I need to change in order for it to work. Here is the link to the library which does mention it supports esp8266. Here is the example code.

There is a really crappy-sounding text to speech library for arduino. I think it's a pretty good feat that the programmer was able to get this to run on an arduino at all, but it sounds even worse than the 80's text-to-speech chips.

There are also pure software TTS solutions available such as this library that claim to run on a plain Arduino Uno without much external hardware other than perhaps some form of amplifier. I have not used this library myself but it looks interesting.
