How To Control a Servo Motor using Joystick DIY Project by WTC Zone

 

To make a servo motor move using a joystick and Arduino Nano, follow these steps:

---

Components Required

1. Arduino Nano
2. Servo Motor (e.g., SG90 or MG996R)
3. Joystick Module
4. Jumper Wires
5. Breadboard
6. Power Source (USB or 5V external power)

---

Connections

1. Joystick Module:

   • VCC → 5V of Arduino Nano
   • GND → GND of Arduino Nano
   • VRx (Horizontal) → A0 of Arduino Nano
   • VRy (Vertical) → A1 of Arduino Nano (Optional if only one axis is needed)

2. Servo Motor:

   • Signal → D9 of Arduino Nano
   • VCC → External 5V power supply (if needed, depending on servo's power requirements)
   • GND → Common ground with Arduino Nano and joystick

Code for Controlling a Servo Motor using Joystick DIY Project by WTC Zone

#include <Servo.h>
// Create a Servo object
Servo myServo;
// Define joystick input pin
const int joystickPin = A0;
// Define the servo control pin
const int servoPin = 9;
void setup() {
  // Attach the servo to the defined pin
  myServo.attach(servoPin);
  // Start serial communication for debugging
  Serial.begin(9600);
}
void loop() {
  // Read the joystick value (0-1023)
  int joystickValue = analogRead(joystickPin);
  // Map the joystick value to the servo's angle range (0-180)
  int servoAngle = map(joystickValue, 0, 1023, 0, 180);
  // Move the servo to the mapped angle
  myServo.write(servoAngle);
  // Print the values for debugging
  Serial.print("Joystick Value: ");
  Serial.print(joystickValue);
  Serial.print(" | Servo Angle: ");
  Serial.println(servoAngle);
  // Small delay for stability
  delay(15);
}

Working Explanation

1. The joystick module's horizontal axis outputs an analog signal between 0 and 1023 based on its position.
2. This analog value is read by the Arduino Nano on pin A0.
3. The map() function converts the joystick's range (0–1023) to the servo motor's range (0–180 degrees).
4. The servo motor moves to the specified angle using the Servo library.

If the servo motor isn't moving, here are a few troubleshooting steps you can follow:

---

Step 1: Verify the Connections

1. Joystick:

   • Confirm the VRx pin is connected to A0 on the Arduino Nano.
   • Ensure the joystick's VCC and GND are properly connected to the Arduino Nano's 5V and GND.

2. Servo Motor:

   • The signal wire should be connected to D9 on the Arduino Nano.
   • Ensure the VCC and GND of the servo motor are connected properly.
   • If the servo requires more current than the Arduino can provide, use an external 5V power supply, and connect all GND pins (Arduino, servo, and power supply) together.

---

Step 2: Check the Power Supply

• Servo motors can draw significant current, especially under load. If you're powering the Arduino via USB, the servo might not receive enough power.
• Use an external 5V power supply or battery for the servo motor.
• Ensure the servo's power supply matches its rated voltage.

Step 6: Common Issues

• Wrong Pin Assignment: Double-check that the pins in the code match the actual wiring.
• GND Not Connected: Ensure all components share a common ground.
• Damaged Components: Test with another servo or joystick module if possible.

---

Tips

• If the servo motor jitters, try adding a capacitor (e.g., 10µF) across its power pins.
• Use an external power source for the servo if it draws too much current.
• You can extend the project to use the vertical axis (VRy) for another servo or other control.
