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.

                    ▶   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.
