Control a Pump with Arduino

This video tutorial explains how to use a DC pump with an Arduino for various projects like irrigation and hydroponics. It covers the importance of understanding pump specifications, such as flow rate and power requirements, and demonstrates how to use Tinkercad for simulating Arduino circuits. The tutorial introduces transistors for controlling pumps and explains how to connect external power supplies for pumps requiring higher voltage. Finally, it shows how to control pump speed using a potentiometer and the analog write command.

What should you consider when purchasing a DC pump for an Arduino project?
