If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump ... are needed to build a relay-driver circuit. Yes, there is a chance to realize ...

First things first, there needs to be a way to turn the current control ... the control knob. An Arduino measures the temperature of the room via a DS18B20 temperature sensor which then has ...

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay, then plug in your fan, and you’re good to go. If that sounds ...
