Sure why not?.....
Who learns to drive in a Porsche or a Lamborghini..??
(I'm thinking... have the hygrometer prongs inserted in the soil of one of my bonsai pots and when the soil gets on the dry side the arduino detects this and then throws a relay that starts the watering/misting system - and then shuts off when the soil gets wet...)My question: do I need an interface between said Hygrometer Module and Arduino...??
