I think that it's fair to consider Arduino's complicated history (the legal battles, the Wiring history, etc.) while also acknowledging how revolutionary it's been to hobbyist electronics. I'm not sure what would be improved by trying to avoid Arduino at this point. Especially considering that it has spawned a very large and versatile ecosystem: all of the open source libraries that have been created for it (some random amazing ones: [0], [1]), the compatible shields and accessories [2], tutorials & courses, etc. It remains an extremely important and useful platform, and for good reason.

NTSC color requires a precise frequency, but if you're fine with just black and white, you can generate NTSC B&W using an Arduino Nano (16 MHz 8-bit processor) and a couple resistors and crocodile clips and an RCA cable. (PAL B&W is similar and also possible.) There are even libraries that make it super easy; I have used this one: https://github.com/Avamander/arduino-tvout (IIRC I needed to fix a couple things to get it to compile). With Raspberry Pi Picos and their 133 MHz clock rate it seems it's possible to even generate HDMI (and there are youtube videos demonstrating this). I recently bought a couple crystals to generate the NTSC color subcarrier frequency. The Arduino Nano only has 2 KB of RAM so it's a very tight fit but I'm daydreaming about running a tiny BASIC interpreter on it like to build something similar to an old 80s compu
