Speed & Direction with an H-Bridge

Control a DC motor with an L298N module.

Spinning Both Ways

A plain transistor runs a motor in one direction. To make wheels go forward and back, you need a smarter circuit called an H-bridge. 🔁

Why the H Shape

An H-bridge uses four switches arranged like the letter H. The motor sits in the middle, and flipping pairs of switches reverses the current through it.
