Above wiring diagram shows a system for controlling a DC motor's direction and speed using a joystick and an L298N motor driver. The L298N receives control signals from an Arduino-Nano microcontroller. The joystick gives user input for both direction (forward/reverse) and velocity (tilt angle) as well. Then the controller decodes these signals and sends command to the L298N driver. After that the L298N reads the commands as controlling current that is supplied to the motor. And enables it to detect direction and speed of motor from joystick position. By following the wiring diagram, you can understand the overview of the operational control of a DC motor using motor driver and joystick.
