Introduction
The multi-function Learning board for Arduino has many of features which makes it ideal for beginners who just want to experiment and learn, or just as a general purpose board for more advanced uses. It has provisions for ADC experiments, General Purpose I/O experiments, Segment Displays, Communications and more.

Features

Plug and play with Arduino Uno or Mega
4 digit 7-segment LED display module
4 x surface mount LEDs
1 x 10K adjustable precision potentiometer for trying ADC experiments.
3 x Independent push buttons

LED Blink Program

To connect the multi function board with Arduino Uno,the user should simply plug or mount it to the Uno board.The program given below is one of the example to do with the multi function board.The user can do various experiments depending on their use.

void setup()
{
  pinMode(13, OUTPUT);
  pinMode(12, OUTPUT);
  pinMode(11, OUTPUT);
  pinMode(10, OUTPUT);
}
void loop()
{
  // led On
  digitalWrite(13, LOW);
  delay(100);
  // led Off
  digitalWrite(13, HIGH);
  delay(100);
    // led On
  digitalWrite(12, LOW);
  delay(100);
  // led Off
  digitalWrite(12, HIGH);
  delay(100);  // led On
  digitalWrite(11, LOW);
  delay(100);
  // led Off
  digitalWrite(11, HIGH);
  delay(100);  // led On
  digitalWrite(10, LOW);
  delay(100);
  // led Off
  digitalWrite(10, HIGH);
  delay(100);
}

POTENTIOMETER Code

/* Define the analogue pin used to read the potentiometer */
#define PotPin 0

void setup()
{
 Serial.begin(9600);

}
/* Main Program */
void loop()

{
 Serial.print("Potentiometer: ");
 Serial.println(analogRead(PotPin));
 
 /* Wait 0.5 seconds before reading again */
 delay(500);
}

Buzzer Test code

/* Define the analogue pin used to read the potentiometer */
#define POT_DIO 0

/* Define the digital pin used to control the buzzer */
#define BUZZER_DIO 3

#define OFF HIGH
#define ON LOW

void setup()
{
 /* Set the buzzer pin to an output and turn the buzzer off */
 pinMode(BUZZER_DIO, OUTPUT);
 digitalWrite(BUZZER_DIO, OFF);

}

void loop()
{
 /* Read the current position of the 10K potentiometer and use it
    as a time delay */
 delay(analogRead(POT_DIO));
 
 /* Turn the buzzer on for 20ms and then turn it back off again */
 digitalWrite(BUZZER_DIO, ON);
 delay(20);
 digitalWrite(BUZZER_DIO, OFF);
