Hey, I recently started research on my arduino project to make a automated water system (without the soil moisture detector) and i was trying to figure out how to connect all the different components. some people say i need to use trasistors and diodes and other people say that i need to use relays. I don't really know what the best method is, can somebody help me please?
List of components i have bought:
-5v water pump
-bread board & jumper wires
The goal is basically just a single arduino with a water pump (5v).
