Interfacing Piezo Element

C/C++
int sensoroutput = 4; // the analog pin connected to the sensor
int ledoutput = 0; // pin connected to LED
int THRESHOLD = 100;
void setup()
{
pinMode(ledPin, OUTPUT);   // this function is used to declare led connected pin as output
}
void loop()
{
int value = analogRead(sensoroutput);  // function to read analog voltage from sensor
if (value >= THRESHOLD)                    // function to check voltage level from sensor
{
digitalWrite(ledoutput, HIGH);
delay(100); // to make the LED visible
}
else

} 

Interfacing Servo Motor

C/C++
#include <Servo.h>

Servo myservo;  // create servo object to control a servo
// twelve servo objects can be created on most boards

int pos = 0;    // variable to store the servo position

void setup() {
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object
}

void loop() {
  for (pos = 0; pos <= 180; pos += 1) { // goes from 0 degrees to 180 degrees
    // in steps of 1 degree
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(15);                       // waits 15ms for the servo to reach the position
  }
  for (pos = 180; pos >= 0; pos -= 1) { // goes from 180 degrees to 0 degrees
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(15);                       // waits 15ms for the servo to reach the position

 Pin 1 to Vout (pin 11 on Arduino)
 Pin 2 to GND
 Pin 3 to Vcc (+5v from Arduino)
