I bought an arduino kit and immediately realized that I still fucking suck at programming. Why won't you compile, you cunt?! Just make the light blink for fucks sake! I also realized I've no idea what I'm going to use it for. I was thinking, some sort of programmable dildobot, like a big floppy dong that I can set loose in public that will sense movement and chase after people. I need ideas. They don't need to be practical.
You could automate light, heat, water, and fertilizer for your tomato plants.
