That's because a toy engineering project is still an engineering project and will be way more work than you think it is, no matter how much work you think it is. It's hard to maintain that energy for long when it's not your day job (sometimes even when it is, tbh).
LOL. I often tell people online that they're better off downloading the free Arduino IDE or playing around with the Wokwi simulator until they have a good idea of what they want to build and whether or not it's within their capabilities before buying parts.
I've built a lot of custom arduino-based projects for other people and a substantial fraction of them are the "I bought a bunch of stuff, but I don't have time to learn how to program it" types.
