SunFounder ESP32 Starter Kit
Current flows from the positive terminal of the battery through the circuit, through the copper brushes to the commuta-
tor, and then to the armature. But because of the two gaps in the commutator, this flow reverses halfway through each
complete rotation.
This continuous reversal essentially converts the DC power from the battery to AC, allowing the armature to experience
torque in the right direction at the right time to maintain rotation.

• 4.1 Motor (Arduino Project)
• 4.1 Small Fan (MicroPython Project)
• 2.9 Rotating Fan (Scratch Project)
