Alignment: Keep the wheels balanced for straight driving.
Support: A caster wheel or glide surface at the front/back ensures stability.
POWER SUPPLY
Voltage: Commonly 6–12V for DC motors.
Battery Packs: 9V blocks, AA batteries, or Li-ion packs.
Regulators: Some motor driver boards include a 5V regulator for powering the Arduino.
REVISIT
▶ A DC motor converts electrical energy into mechanical energy through electromagnetic interactions.
▶ A motor often draws more current than an Arduino pin can handle.
▶ Drivers use an H-bridge circuit, letting you reverse polarity for forward/ reverse spinning.
▶ Shields the microcontroller from electrical noise and voltage spikes generated by the motor.
▶ The Adafruit Motor Shield is a great and quick way to control DC motors, servos or even stepper motors.
