• 1 - Bouton

#include <Servo.h>

Servo myservo;                      // create servo object to control a servo

const int servoPin = 9;             // Digital PWM pin used to control the servo
const int buttonPin = 8;            // Digital pin to attach the button

int val = 0;                        // variable to read the value from the button

void setup() {
  myservo.attach(servoPin);         // attaches the servo to "servoPin"
}

void loop() {
  val = digitalRead(buttonPin);     // gets button current state 
  if (val == 0) {                   // checks if the button is pressed
    myservo.write(120);             // lifts finger
  }
  else {
    myservo.write(10);              // lowers finger
  }
  delay(30);                        // waits for servo to get there
}

• 2 - Photo-interrupteur

#include <Servo.h>

Servo myservo;                      // create servo object to control a servo

const int servoPin = 9;             // Digital PWM used to control the servo
const int photoPin = 8;             // Digital pin used to control the photo interruptor

int val = 0;                        // variable to read the value from the photo interruptor

void setup() {
  myservo.attach(servoPin);         // attaches the servo to "servoPin"
}

void loop() {
  val = digitalRead(photoPin);      // reads value from photo interruptor 
  if (val == 1) {                   // check if the photo interruptor is blocked
    myservo.write(120);             // lifts finger
  }
  else {
    myservo.write(10);              // lowers finger
  }
  delay(30);                        // waits for servo to get there
}

• 3 - Photorésistance

#include <Servo.h>

Servo myservo;                            // create servo object to control a servo

const int photoResistPin = A0;            // Analog pin used to connect the photo resistor 
const int servoPin = 9;                   // Digital PWM used to control the servo

int light = 0;                            // variable to read the value from the photo resistor pin

void setup() {
  myservo.attach(servoPin);               // attaches the servo to "servoPin"
  pinMode(photoResistPin, INPUT);         // puts the photo-resistor pin in INPUT
}

void loop() {
  light = analogRead(A0);                 // reads value from photo-resistor
  light = map(light, 0, 1023, 180, 0);    // scales it to be usable by the servo
  myservo.write(light);                   // sets the servo position according to the value
  delay(30);                              // waits for the servo to get there
}

• 4 - Joystick

#include <Servo.h>

Servo myservo;                            // create servo object to control a servo

const int joystickPin = A0;               // Analog In pin used to connect the joystick
const int servoPin = 9;                   // Digital PWM used to control the servo

int rotation = 0;                            // variable to read the X or Y value from the joystick


void setup() {
  myservo.attach(servoPin);               // attaches the servo to "servoPin"
  pinMode(joystickPin, INPUT);         // puts the joystick pin in INPUT
}

void loop() {
  rotation = analogRead(A0);                 // reads value from joystick
  rotation = map(rotation, 0, 1023, 180, 0);    // scales it to be usable by the servo
  myservo.write(rotation);                   // sets the servo position according to the value
  delay(30);                              // waits for the servo to get there
