Robotics Motor Control in Robotics
Motor control requires: (1) power supply (enough current for motor), (2) motor driver (interfaces microcontroller to motor), (3) PWM signal (varies speed).
The L298N is a popular dual-motor driver. It has two motor outputs (each controlled by 2 pins: direction + speed). PWM on the speed pin ranges 0–255 for 0–100% power.
Differential drive (two motors, independent control) is standard for mobile robots. Left/right speed difference = turning.
