// Functions

1. Button -
   * Button Class has function :
       a) onoff(int BUTTON_PIN, int LED_PIN); -
          Checks the button, if pressed led is put on.
          Else it is off.


2. Buzzer -
   * Buzzer Class has the functions :
       a) playmelody(int BUZZER_PIN, int Length, char note[], int duration, int tempo); -
          Play the melody that is entered in the note[] of string length : Length, duration of each note.
          And Tempo can be in the range of 300....

 * note      frequency       period
 * c          261 Hz          3830
 * d          294 Hz          3400
 * e          329 Hz          3038
 * f          349 Hz          2864
 * g          392 Hz          2550
 * a          440 Hz          2272
 * b          493 Hz          2028
 * C          523 Hz          1912

       b) playNote(int BUZZER_PIN, char note, int duration); -
          Plays the single note in the above frequency


3. Car -
   * Car Class has the functions(using simple DC Motor) :
       a) run(int pin1,int pin2,int pin3,int pin4,int s); -
           Runs both the motors with equal voltage and the speed of the motor can be selected with s
           s=1 => 25% Speed
           s=2 => 50% Speed
           s=3 => Full speed

       b) turn(int pin1,int pin2,int pin3,int pin4,int s); -
           Runs both the motors with unequal voltage to turn the motor and direction of turn can be selected with s
           s=1 => Left
           s=2 => Right


4. LED -
   * LED Class has the functions :
       a) on(int LED_PIN);
          Active high. LED is put on.

       b) off(int LED_PIN);
          Active low. LED is put off.
       c) blink(int LED_PIN, int time1, int time2);

          Active high and low. LED is put on in time1 and off in time2.
       d) fade(int LED_PIN, int time);
          From active low to high in time duartion of 'time' in 20 steps.

       e) bright(int LED_PIN, float bright);
          A constant brighten led with 'bright' in percentage.


5. Light -
   * LED Class has function :
       a) read(int LIGHT_PIN, int LED_PIN, int threshold);
          It reads the light amount and if the value is beyond a 'threshold' value it puts on the led.

6. Line_Follow -
   * Line_Follow has function :
       a) run(int int led, int LS, int RS, int LM1, int LM2, int RM1, int RM2)
          This function is a simple line follower, with 'led' as IR LED, 'LS' and 'RS' as Left and Right IR Sensor,
          LM1 and LM2 the left motor pins(LM1 +ve), RM1 and RM2 the right motor pins(RM1 +ve)

7. Rotary -
   * Rotary Class has function :
       a) angle(int ROTARY_PIN);
          It reads angle of the rotary sensor knob and prints it in the serial monitor.


8. Sound -
   * Sound Class has function :
       a) check(int SOUND_PIN);
          It reads the sound in the surrounding and prints its value in the serial monitor.


9. Temp -
   * TEMP Class has function :
       a) read(int TEMP_PIN);
          It reads the temperature and prints it in the serial monitor.


10. Touch -
   * Touch Class has function :
       a) onoff(int TOUCH_PIN, int LED_PIN);
          It reads the touch sensor and puts on the LED if touched and off is not touched(the sensor).


11. Ultra -
   * Ultra Class has function :
       a) start(int pin1)
          It sends the ultrasound from pin1

       b)  check(int pin2)
          It checks for the recieved ultrasound in pin2. The threshold value of detction is set as 1000(Analog read).
