About this project

Solves the classic 'forgot to water the plants' problem: a soil-moisture sensor feeds an Arduino UNO R4 WiFi, which reports moisture levels to the Blynk app and lets the user switch a relay-driven water pump on remotely from anywhere. A nice touch is the onboard LED matrix, which displays a simple happy/neutral/sad face expression depending on how dry the soil currently is.
