The joystick module contains dual potentiometers that generate analog signals corresponding to its horizontal and vertical movements. The Arduino Nano reads these continuous analog voltage inputs, processes the data, and translates them into appropriate Pulse Width Modulation (PWM) signals to adjust the rotational position of the servo motor in real-time.
Why Build This

Skills You'll Learn
Reading analog sensor data from a joystick
Controlling servo motor angles with PWM signals
Integrating input devices with actuators
Basic electronics wiring and debugging
Safety Precautions
Ensure correct power and ground connections to prevent short-circuiting the Arduino Nano or the joystick module. Double-check servo motor current requirements to avoid drawing excessive power directly from the microcontroller's 5V pin. Always disconnect power before making any modifications to the wiring schematic.

Frequently Asked Questions
For small servos under light loads, the Arduino's 5V pin may suffice, but it is recommended to use an external power source for the servo to prevent voltage drops and microcontroller resets.
You can use the standard Arduino Servo library included in the Arduino IDE to easily control the servo motor angles.
Yes, you can map the X-axis to one servo and the Y-axis to a second servo for two-axis directional control.
