First of all, it is my first topic and i want to say hi to you all!! Secondly, i am really a terrible noob and sorry for that :(
I need to make a smart greenhouse project with Arduino Mega 2560, and i found a video to help me with my servomotor(MG996R) which will start working when raindrops module detect rain and 12v DC Fan which will start working when LM35 sensor calculates the weather as hot. However, my third actuator, 5V DC Mini Water Pump, which needs to become turned on when soil humidity sensor measures the soil as dry, is where i am left without an opinion. All the water pumps people use is 12 V, so i dont know which specific components i should use. I researched a bit and found that people use transistors and diodes for it. Which ones should i use and how to make the connections?
I would appreciate if someone helps me what components, specifically, should i buy and how to connect them together with Arduino 2560? It would be great if you can draw it, like with fritzing or something.
Thanks if you read this far :)
