Raspberry Intelligent Fan

Mini Fan

To make the intelligent fan, we will use the Grove - Mini Fan, which consists of a motor drive board, DC motor, film blade and Grove connecting cables, as shown in the figure below. In general, motors can be divided into DC motors and AC motors according to the different input currents. Here, we use a DC motor. DC motors can realize the mutual conversion of electrical energy and mechanical energy so that electricity supplied to the motor can be used to drive other mechanical components.

A DC motor is composed of a stator and a rotor. The main function of the stator is to produce a magnetic field, and the main function of the rotor is to produce electromagnetic torque and induced electromotive force. In short, the DC motor works according to the principle that a conductor which carries an electrical current experiences a force in the magnetic field. Motors are widely used in our daily life, such as in industry, agriculture, and other applications where power is needed.
