It doesn’t matter if you connect the wire to the positive (cathode) or the negative (anode) terminal of the battery.
Note that for power sources, the cathode and anode are marked opposite to that of diodes and other electronics. In them, the cathode is the positive terminal and the anode is the negative one.

Discover the fun of DIY electronics with your child in this self-paced, beginner-friendly online course, where parents and kids work together to build a rotating LED strip display!
Designed for those with no prior experience, this project-based course walks you through the entire process of assembling a spinning LED display that uses persistence of vision to create a glowing clock.
The goal of this lesson is to build a simple circuit to control the motor. We’ve split the steps into small tasks.
If any step is unclear, there’s a 3D model at the end that shows what the finished circuit looks like. Feel free to take a peek.
