“Some plants require much care and attention. This can be difficult if you’re about to leave your home for a longer period of time. This issue could be solved with an innovative automatic plant watering system, which also measures the moisture level of the soil, regulating the amount of water received by the plant. The system could be manufactured by using a 3D printer, but we will focus on using items commonly found in most households, since not so many people own a 3D printer. The items you will need are: an Arduino Uno (or any other Arduino compatible board), jumper wires, a breadboard, two nails, a push button, 30cm of IV tube, a servo motor (doesn’t need to have much torque), a 10k resistor, a 4.7k resistor and a 10nF ceramic capacitor. The 10k resistor and ceramic capacitor are used to hardware debounce the push-button. The button is used more for debugging purposes, by actuating the system manually, by the push of a button.”
