Growing plants with LEDs certainly works, I'm just wondering if the power of a USB port is enough
Is this a painting, or actual fruit?
If fruit, how long did it last until the apples turned brown?
there's no need for relays if you have low voltage
That's a good point. Also makes me wonder if those lights will actually make a difference when it comes to plant growth, given the low power.
It's not completely stupid. One pissible issue: when the light level is around the threshold, slight variations (think: cloud passing by) will cause the relay to switch back and forth quickly. This can be solved with some additional parts (keyword: hysteresis).
I would recommend using a microcontroller, it makes this problem easy to solve, plus you can have more logic to trigger the lights (eg time based).
Another thing is turning off: if it's purely based on light level, you need to make sure the sensor does not "see" any of the LED light, otherwise it thinks the sun is back up
Yeah, mini is the best! It is robust and has a ahape that makes it easy to figure out which way to plug it. I love it when i fet a device with a mini
That's a common misconception. The cybertruck's sails are designed to be pushed by a high-power stream of gasoline, not wind
