I'm trying to build a very simple, stupid light switch for my grow light. Essentially, I want to turn on the light, if it gets too dark outside, so that my plants can survive the northern winter.
Since I'm a software guy, my first thought was an ESP32, but that seems excessive.
My current approach would be something like this:

In conjunction with a relay, both powered by a USB-PSU.
If the light level is low enough, the logic DO pin should send a signal and that should be enough to trigger a small relay, so that the relay then closes the circuit to switch on the lights.
Is that idea completely stupid? With electronics, I'm usually missing something very obvious.
The lights themselves are already just usb powered and only draw 5W, so that shouldn't be problem.
What I'm concerned with is the actual switching. Is the logic signal "strong" enough to activate a relay? Would simple transistor maybe sufficient?
And that is a deeply deeply undemocratic thing to say.
You're taking away all agency from the voters. In what you're saying, voters are completely unable to understand anything and are led by elites against their own will. This is how Putin, Hitler, Xi think about their subjects.
There is manipulation, without any doubt, but every single voter in a free country, like the US, has the ability to see through that. They have all the information they need, they have the critical thinking abilities they need, but they choose not to use them.
Listen to interviews with Trumpets. They know, he's lying. It's clear to them. But they like the sentiment of his lies and that's good enough for them. They are to blame. And whoever chose not to vote against open fascism is also to blame.
I'm German, and the "We didn't know of anything!!!" quote of the willfully ignorant Germans 80 years ago is infamous here.
