-New Innovators: Lab 1

Difficulty Level (1-5)

Level 2

Time To Complete

Approximately 15 minutes

Challenge Description

Make one LED to blink on low power for two times, wait for 3 seconds, and blink on high power for one time. The LED will blink continuously.

Hint

Every second is 1000 for delay function

Answer

Code: int ledPin = 13;  void setup()  {    pinMode(ledPin, OUTPUT);  } void loop()  {   digitalWrite(ledPin, LOW);   delay(1000);   digitalWrite(ledPin, LOW);   delay(3000);   digitalWrite(ledPin, HIGH);   delay(1000); } Photos:

This lab will teach you how to make music with piezo element.

Equipment:
-1 piezo element 
-1 wire (any colour) 
-2 wires (black) 
-1 Arduino UNO 
-1 breadboard 
-1 USB cable

Program Details:
-Download Arduino here

Time to Program and Complete:
-Approximately 30 min

Results:
-The pins under the buzzer were not in the correct holes, but after I fixed them the buzzer made music

Photo/Video:

Program:
int speakerPin = 9;
int length = 15; 
char notes[] = "ccggaagffeeddc ";
int beats[] = { 1, 1, 1, 1, 1, 1, 2, 1, 1, 1, 1, 1, 1, 2, 4 };
int tempo = 300;
void playTone(int tone, int duration) 
{
  for (long i = 0; i < duration * 1000L; i += tone * 2)
  {
    digitalWrite(speakerPin, HIGH);
    delayMicroseconds(tone);
    digitalWrite(speakerPin, LOW);
    delayMicroseconds(tone);
  }
}
void playNote(char note, int duration)
{
  char names[] = { 'c', 'd', 'e', 'f', 'g', 'a', 'b', 'C' };
  int tones[] = { 1915, 1700, 1519, 1432, 1275, 1136, 1014, 956 };
  for (int i = 0; i < 8; i++)
  {
     if (names[i] == note) 
    {
      playTone(tones[i], duration);
    }
  }
}
void setup()
{
  pinMode(speakerPin, OUTPUT);
}
void loop()
{
  for (int i = 0; i < length; i++)
  {
    if (notes[i] == ' ') 
    {
      delay(beats[i] * tempo);
    }
    else
    {
      playNote(notes[i], beats[i] * tempo);
     }
    delay(tempo / 2);
  }
}

Arduino Lab 4: Potentiometer (Twist Pot)

Purpose:
This lab will teach you how to make one LED blink faster or slower when you turn the potentiometer.
Modified: The modified version will make the LED fade when you turn the potentiometer.

Equipment:
-1 potentiometer (10k ohms)
-1 330 ohm resistor
-1 LED (any colour)
-1 wire (red)
-1 wire (black)
-4 wires (any colour) 
-1 USB cable 
-1 breadboard 
-1 Arduino UNO

Program Details:
-Download Arduino here

Time to Program and Complete:
-Approximately 35 min (for 2 parts)

Results:
-There were some spelling mistakes in the code, but after I fixed them it worked completely fine.

Photo/Video:

Modified Program

Program:
int sensorPin = A0;
int ledPin = 13;
int sensorValue = 0;
void setup()
{
  pinMode (ledPin , OUTPUT);
}
void loop()
{
  sensorValue = analogRead(sensorPin);
  digitalWrite(ledPin , HIGH);
  delay(sensorValue);
  digitalWrite(ledPin, LOW);
  delay(sensorValue);
}

Program Modifications:
--Modified version-- To make the LED fade when we turn the potentiometer.

int sensorPin = A0;
int ledPin = 9;
int senorValue = 0;
void setup()
{
  pinMode(ledPin, OUTPUT);
}
void loop()
{
  int value = analogRead(sensorPin) / 4;
  analogWrite (ledPin, value);
}

Helpful Tips:
-Check spelling
