Task 40 - Article from YABB



This article was quite interesting. It is about a music LED visualizer which outputs different lights, when a song is being played. I was thinking about doing something similar for my major project, however it is a little confusing on how it is done. I will need to read up on it further.

Task 39 - Same As Task 38 With Different Output

//Program to output the value of your LDR whenever you press the button.

int buttonPin = 2; // the number of the pushbutton pin
int photocellPin = 0; // the cell and 10K pulldown are connected to a0
int photocellReading; // the analog reading from the analog resistor divider
int buttonState = 0; // variable for reading the pushbutton status
int count = 1;

void setup() {
// initialize the pushbutton pin as an input:
pinMode(buttonPin, INPUT);
Serial.begin(9600);
}

void loop(){

photocellReading = analogRead(photocellPin);
buttonState = digitalRead(buttonPin);

if (buttonState == HIGH) {
Serial.print("Reading number ");
Serial.print(count);
Serial.print(": ");
Serial.println(photocellReading);
delay(500);
count++;
}
else {
buttonState == LOW;
}
}

Task 38 - Program to output the value of your LDR whenever you press the button.

//Program to output the value of your LDR whenever you press the button.

int buttonPin = 2; // the number of the pushbutton pin
int photocellPin = 0; // the cell and 10K pulldown are connected to a0
int photocellReading; // the analog reading from the analog resistor divider
int buttonState = 0; // variable for reading the pushbutton status

void setup() {
// initialize the pushbutton pin as an input:
pinMode(buttonPin, INPUT);
Serial.begin(9600);
}

void loop(){

photocellReading = analogRead(photocellPin);
buttonState = digitalRead(buttonPin);

if (buttonState == HIGH) {
Serial.print("Analog reading = ");
Serial.println(photocellReading);
delay(500);
}
else {
buttonState == LOW;
}
}

Task 37 - Baud Rate

I have found with using the code from task 36, I could increase the baud rate upto 28800 before it started to become scrambled on the screen. The least amount of baud rate I could use was 9600, if I used anything less, the words became scrambled or wouldn't show anything on the screen.

Task 36 - Random Numbers with Mean

// Adam Randall - Random Numbers Program, generates 100 random numbers between 1 and 10 and display mean.

long randNumber;
int total;
int mean;

void setup(){
total =0;
mean =0;
Serial.begin(9600);
randomSeed(analogRead(0));
for (int i=0; i<100; i++){
randNumber = random(0, 10);
Serial.print(i);
Serial.print(": ");
Serial.println(randNumber);
total = total + randNumber;
delay(500);
}
mean = (total/100);
Serial.println ("The Mean is: ");
Serial.print(mean);
}

void loop() {
}

Task 35 - Random Numbers with numbers in front

// Adam Randall - Random Numbers Program, generates 100 random numbers between 1 and 10

long randNumber;

void setup(){
Serial.begin(9600);
randomSeed(analogRead(0));
for (int i=0; i<100; i++){
randNumber = random(0, 10);
Serial.print(i);
Serial.print(": ");
Serial.println(randNumber);
delay(500);
}
}

void loop() {
}
