Introduction

In this article, I am explaining about controlling the ServoMotor using Potentiometer in Arduino. In this article, I will control the Servo Motor in the adjustment of Potentiometer.
Parts of the List
  • Arduino Uno
  • Potentiometer
  • Servo Motor
  • Bread Board
  • Hook up wires
Connection
Servo Motor
  • Connect the Vcc of the Servo Motor to the 5v of the Arduino Uno.
  • Connect the gnd of the Bluetooth to the Gnd of the Arduino Uno.
  • Connect the Vin of the Bluetooth to the 09 of the Arduino Uno.
Potentiometer
  • Connect as per the preceding figure to the Arduino board and the LCD Display.
  • The Vin is connected to the LCD display in 03.
Programming
  1. #include <Servo.h>
  3. const int servo1 = 3; // first servo
  4. const int servo2 = 10; // second servo
  5. const int servo3 = 5; // third servo
  6. const int servo4 = 11; // fourth servo
  7. const int servo5 = 9; // fifth servo
  8. const int joyH = 2; // L/R Parallax Thumbstick
  9. const int joyV = 3; // U/D Parallax Thumbstick
  10. const int joyX = 4; // L/R Parallax Thumbstick
  11. const int joyP = 5; // U/D Parallax Thumbstick
  12. const int potpin = 0; // O/C potentiometer
  14. int servoVal; // variable to read the value from the analog pin
  17. Servo myservo1; // create servo object to control a servo
  18. Servo myservo2; // create servo object to control a servo
  19. Servo myservo3; // create servo object to control a servo
  20. Servo myservo4; // create servo object to control a servo
  21. Servo myservo5; // create servo object to control a servo
  22. void setup() {
  24. // Servo
  25. myservo1.attach(servo1); // attaches the servo
  26. myservo2.attach(servo2); // attaches the servo
  27. myservo3.attach(servo3); // attaches the servo
  28. myservo4.attach(servo4); // attaches the servo
  29. myservo5.attach(servo5); // attaches the servo
  31. // Inizialize Serial
  32. Serial.begin(9600);
  33. }
  36. void loop(){
  38. servoVal = analogRead(potpin);
  40. servoVal = map(servoVal, 0, 1023, 0, 179);
  42. myservo5.write(servoVal);
  44. delay(15);
  45. // Display Joystick values using the serial monitor
  46. outputJoystick();
  48. // Read the horizontal joystick value (value between 0 and 1023)
  49. servoVal = analogRead(joyH);
  50. servoVal = map(servoVal, 0, 1023, 0, 180); // scale it to use it with the servo (result between 0 and 180)
  52. myservo2.write(servoVal); // sets the servo position according to the scaled value
  54. // Read the horizontal joystick value (value between 0 and 1023)
  55. servoVal = analogRead(joyV);
  56. servoVal = map(servoVal, 0, 1023, 70, 180); // scale it to use it with the servo (result between 70 and 180)
  58. myservo1.write(servoVal); // sets the servo position according to the scaled value
  60. delay(15); // waits for the servo to get there
  62. // Read the horizontal joystick value (value between 0 and 1023)
  63. servoVal = analogRead(joyP);
  64. servoVal = map(servoVal, 0, 1023, 70, 180); // scale it to use it with the servo (result between 70 and 180)
  66. myservo4.write(servoVal); // sets the servo position according to the scaled value
  68. delay(15); // waits for the servo to get there
  69. // Read the horizontal joystick value (value between 0 and 1023)
  70. servoVal = analogRead(joyX);
  71. servoVal = map(servoVal, 0, 1023, 70, 180); // scale it to use it with the servo (result between 70 and 180)
  73. myservo3.write(servoVal); // sets the servo position according to the scaled value
  75. delay(15); // waits for the servo to get there
  77. }
  80. /**
  81. * Display joystick values
  82. */
  83. void outputJoystick(){
  85. Serial.print(analogRead(joyH));
  86. Serial.print ("---");
  87. Serial.print(analogRead(joyV));
  88. Serial.println ("----------------");
  89. Serial.print(analogRead(joyP));
  90. Serial.println ("----------------");
  91. Serial.print(analogRead(joyX));
  92. Serial.println ("----------------");
  93. }
