The PWM output from Arduino’s pins D5 and D6 are connected to the motor driver input pins IN1 and IN2.The X and Y pins are analog output that’s connected with Arduino’s analog pins A0 and A1.The Vcc pin is given a 5V supply from the Arduino board and the GND pin is connected with the board’s ground. The joystick has five interfacing pins: Vcc, GND, X, Y, and button.The circuit is built using three major building blocks with an Arduino NANO board, a two-axis resistive joystick, and an L298 motor driver:
It uses a two-axis resistive joystick using an Arduino NANO development board to control an L298 motor driver. The project given below demonstrates using a joystick to control the speed and direction of a DC motor. In some, only the direction of the motor is altered (such as for RC toys) whereas in other applications, both the direction and speed are varied (such as for video camera cranes, jog controls, etc.). There are many other applications as well, where the DC motor that drives the load is controlled by a joystick. Remote-controlled (RC) toys, such as planes, helicopters, boats, cars, etc. The joystick control method for DC motors is currently used in several different applications, including as:ġ. So, users can control the DC motor speed in this way. When the joystick is moved up or down, the motor rotates in the same direction - either forward or in reverse.Īdditionally, the further away from the center the joystick is pushed (in either direction), the faster the motor speed will be in that same direction. How it works: when the joystick is at the center position, the DC motor stops. But another option that’s gaining popularity is controlling the speed and direction of a DC motor by using a joystick. PMW has become a commonly used method to do just this. This means that the DC motor speed varies with the pulse width. And, to vary the DC motor speed, a pulse-width modulation (PWM) signal or wave must be applied to it.Īs the pulse width increases, the average voltage applied to the motor will also increase - and vice versa. To change the direction of the motor, however, the supply it receives must be reversed. Much like the name suggests, DC motor controllers control the speed and direction of a DC motor.
