Show HN: Plant watering system with Arduino Nano

Category: other

Tags: arduino, embedded, iot, automation, electronics

Score: 3.8/10 (Innovation: 3, Technical: 4, Documentation: 5, Utility: 3)

A hobbyist Arduino Nano-based automatic plant watering system using a capacitive moisture sensor and a MOSFET-driven pump controller. It's a well-documented personal project that demonstrates basic embedded electronics and low-side switching, but offers little novel technical contribution beyond a typical DIY tutorial.

Target audience: hobbyist makers and embedded beginners
