Run two DC motors forward, backward, and at any speed with a single L298N module — the workhorse H-bridge behind every small robot, conveyor demo, and remote-controlled car project.

Difficulty: Breadboard. Estimated build time: about 35 minutes. Estimated parts cost: about US$6.80. 5-part bill of materials with live supplier pricing. A motor controller that lets you spin two DC motors independently in either direction at any speed you choose — without the motor noise or current draw destroying your MCU.
