DESTRUCTION OF THE WORLD!

We have now decided to concentrate on when people call to the phone to activate and start some kind of process but not controlling the process with their own phones.
We removed the vibrator from the phone and connected wires to the Arduino instead and programmed it so that it senses when someone calls because then signals are sent in the phone to activate the vibrator.
The arduino is then supposed to activate some kind of drawing robot that is all the time waiting for someone to call. Probably we will use the insides of a radiocontrolled or IR-controlled car with a pen attached to it.
We will see what happens. Time is not on our side.

Time to write about our project maybe?
We are now connecting a cell phone to a DTMF receiver and we are going to transform DTMF signals from the phone into digital input to the Arduino board. What we will make from this is yet unknown to the world but we do know that we want people to be able to call our phone and control something, some kind of output, by pushing the buttons on their own phones.
Everything with the Arduino board and receiver is set up and connected but we need things to open the phone and connect everything to it. Waiting, it's really terrible. Especially when we have to destroy the world before June.

So what is happening?
Here is a clue...

silly mistake...

Today we got fan-mail to our blog and it seems like someone saw what we were to tired and blind to see, the mistake in the second program for the digit display. OMG how could we miss that??? Maybe because it was over 27 C in the computer room and we were hallucinating seeing palm trees and lakes and floating animals in the air.

"Thomas said...
Hej! Ni löste det redan på andra försöket, men ni glömde ändra vilken array den skulle hämta pindata från. Dvs showone()-funktionen checkar i number1[] om den aktuella pinnen ska vara tänd, men sen har ni glömt ändra till number2, number3 osv på nästföljande funktioner.
Fast den sista lösningen var snygg! Optimerat och fint."

For you non-swedes I can tell you that what he wrote was that we missed to change to number2, number3 and so on...:

void showone() {

for(int i = 0; i <>
{ if (number1[i] == 1) {
digitalWrite(ledpins[i], HIGH) ;
}

else {
digitalWrite(ledpins[i], LOW) ;
}
}
}
void showtwo() {

for(int i = 0; i <>
{ if (number1[i] == 1) {
digitalWrite(ledpins[i], HIGH) ;
}

We should of course have written number2 here... Well we are happy with the program that turned out in our third try-out, it worked out well but we will check if the second program works with the changes next time we are gathered with our arduino board around a computer.
THANK YOU THOMAS! Everyone, write to us! We are happy for all tips and comments.

1, 2, 3......?

Our last project has been to have a lightsensor show with numbers the brightness in the room.

We wrote a serial program to find the range of the sensor. The range was from 0 to about 150. Our digit display can show the numbers 0 to 9 so we divided the range in to ten different segments. Then we programmed the Arduino to have the digit display show a higher number the brighter it is.

This is the first program:
________________________________________________________________________

//int ledPin = 13; // LED connected to digital pin 13
int analogPin = 5; // potentiometer connected to analog pin 3
int val = 0; // variable to store the read value
//int threshold = 80; // threshold
int ledPin1 = 8;
int ledPin2 = 10;
int ledPin3 = 2;
int ledPin4 = 3;
int ledPin5 = 4;
int ledPin6 = 5;
int ledPin7 = 6;
int ledPin8 = 7;
int numberzero[] = {1, 1, 1, 1, 1, 1, 0, 1} ;

void setup()
{

pinMode(ledPin1, OUTPUT); // sets the digital pin 8 as output
pinMode(ledPin2, OUTPUT); // sets the digital pin 10 as output
pinMode(ledPin3, OUTPUT); // sets the digital pin 2 as output
pinMode(ledPin4, OUTPUT); // sets the digital pin 3 as output
pinMode(ledPin5, OUTPUT); // sets the digital pin 4 as output
pinMode(ledPin6, OUTPUT); // sets the digital pin 5 as output
pinMode(ledPin7, OUTPUT); // sets the digital pin 6 as output
pinMode(ledPin8, OUTPUT); // sets the digital pin 7 as output

// pinMode(ledPin, OUTPUT); // sets the digital pin 13 as output
Serial.begin(9600);
}
void loop()
{
val = analogRead(analogPin); // read the input pin

//Serial.print("the value of the sensor is: ");
Serial.print(val);
Serial.print("\n");

if (val < 15)
{
showzero() ;
} else if (val <30)
{
showone();

} else if (val < 45) {
showtwo() ;
}

// else if (val < 60) {
// showthree() ;
// }

else {

showthree() ;
}

delay(500) ;
}
void showzero()
{
digitalWrite(ledPin1, HIGH);
digitalWrite(ledPin2, HIGH);
digitalWrite(ledPin3, HIGH);
digitalWrite(ledPin4, HIGH);
digitalWrite(ledPin5, HIGH);
digitalWrite(ledPin6, HIGH);
digitalWrite(ledPin7, LOW);
digitalWrite(ledPin8, HIGH);

}
void showone()
{
digitalWrite(ledPin1, LOW);
digitalWrite(ledPin2, HIGH);

}

For some reason we could only get it to work from 0 until the number 3 so here you can see that we removed number 4 and couldn't continue with the program. We tried it in another way!

This is the second program:
________________________________________________________________________

//int ledPin = 13; // LED connected to digital pin 13
int analogPin = 5; // potentiometer connected to analog pin 3
int val = 0; // variable to store the read value
//int threshold = 80; // threshold

int number0[] = {1, 1, 1, 1, 1, 1, 0, 1} ;
int number1[] = {0, 1, 0, 1, 0, 0, 0, 0} ;
int number2[] = {1, 0, 1, 1, 1, 0, 1, 0} ;
int number3[] = {1, 1, 0, 1, 1, 0, 1, 0} ;
int number4[] = {0, 1, 0, 1, 0, 1, 1, 0} ;
int ledpins[] = {8, 10, 2, 3, 4, 5, 6, 7} ;

void setup()
{

for(int i = 0; i < 8; i++) {

pinMode(ledpins[i], OUTPUT) ;
}
Serial.begin(9600);
}
void loop()
{
val = analogRead(analogPin); // read the input pin

Serial.print("the value of the sensor is: ");
Serial.print(val);
Serial.print("\n");

if (val < 15)
{
showzero() ;
} else if (val <30)
{
showone();
} else if (val <45)
{
showtwo();
} else if (val <60)
{
showthree();

} else {
showfour() ;
}

delay(500) ;
}
void showzero() {

for(int i = 0; i < 8; i++) {

if (number0[i] == 1) {
digitalWrite(ledpins[i], HIGH) ;
}

else {
digitalWrite(ledpins[i], LOW) ;
}

}
}
void showone() {

for(int i = 0; i < 8; i++) {

if (number1[i] == 1) {
digitalWrite(ledpins[i], HIGH) ;
}

else {
digitalWrite(ledpins[i], LOW) ;
}
}
}
void showtwo() {

for(int i = 0; i < 8; i++) {

if (number1[i] == 1) {
digitalWrite(ledpins[i], HIGH) ;
}

else {
digitalWrite(ledpins[i], LOW) ;
}
}
}
void showthree() {

for(int i = 0; i < 8; i++) {

if (number1[i] == 1) {
digitalWrite(ledpins[i], HIGH) ;
}

else {
digitalWrite(ledpins[i], LOW) ;
}
}
}
void showfour() {
Serial.println("Starting showing four") ;
for(int i = 0; i < 8; i++) {

if (number1[i] == 1) {
digitalWrite(ledpins[i], HIGH) ;
}

else {
digitalWrite(ledpins[i], LOW) ;
}
}
}

This program we could only get to work to the number 0 to 1.
WHAT IS THE PROBLEM?

BUT FINALLY we got it to work with a shorter program. HAPPY TIME WE LOVE LIFE AGAIN. Here is the program:

________________________________________________________________________

//int ledPin = 13; // LED connected to digital pin 13
int analogPin = 5; // potentiometer connected to analog pin 3
int val = 0; // variable to store the read value
//int threshold = 80; // threshold

int number[][8] = { {1, 1, 1, 1, 1, 1, 0, 1}, {0, 1, 0, 1, 0, 0, 0, 0}, {1, 0, 1, 1, 1, 0, 1, 0}, {1, 1, 0, 1, 1, 0, 1, 0}, {0, 1, 0, 1, 0, 1, 1, 0}, {1, 1, 0, 0, 1, 1, 1, 1} } ;

int ledpins[] = {8, 10, 2, 3, 4, 5, 6, 7} ;

void setup()
{

for(int i = 0; i < 8; i++) {

pinMode(ledpins[i], OUTPUT) ;
}

Serial.begin(9600);
}

void loop()
{
val = analogRead(analogPin); // read the input pin

Serial.print("the value of the sensor is: ");
Serial.print(val);
Serial.print("\n");

if (val < 15)
{
show(0) ;
} else if (val <30)
{
show(1);
} else if (val <45)
{
show(2);
} else if (val <60)
{
show(3);

} else if (val <75)
{

show(4) ;

} else
{
show(5);

}

delay(500) ;
}

void show(int n) {

for(int i = 0; i < 8; i++) {

if (number[n][i] == 1) {
digitalWrite(ledpins[i], HIGH) ;
}

else {
digitalWrite(ledpins[i], LOW) ;
}

}
}

________________________________________________________________________

As you see we only went up to 5 but you can see the principle.
You just have to write one {1, 1, 1, 1, 1, 1, 0, 1} like this for every number left (6-9) according to what needs to be lit to show it.

And continue writing the loop until the last thing would be:

} else if (val <135)
{

show(8) ;

} else
{
show(9);

Today we built an evil diskomachine with beautful noise and a blinking 8 with some other lamps. The speed and volume was changing with a lightsensor detecting the light. Happy time.

DISKO RECEPT

int earPin1 = 13; // earphone connected to digital pin 13
int ledPin2 = 12; // LED connected to digital pin 12
int ledPin3 = 11; // LED connected to digital pin 11
int butPin4 = 10; // button connected to digital pin 10
int butPin5 = 9; // button connected to digital pin 9
int butPin6 = 8; // button connected to digital pin 8
int butPin7 = 7; // button connected to digital pin 7

int analogPin = 3; // potentiometer connected to analog pin 3
int val = 0; // variable to store the read value

void setup()
{
pinMode(earPin1, OUTPUT); // sets the digital pin 13 as output
pinMode(ledPin2, OUTPUT); // sets the digital pin 12 as output
pinMode(ledPin3, OUTPUT); // sets the digital pin 11 as output
pinMode(butPin4, OUTPUT); // sets the digital pin 10 as output
pinMode(butPin5, OUTPUT); // sets the digital pin 9 as output
pinMode(butPin6, OUTPUT); // sets the digital pin 8 as output
pinMode(butPin7, OUTPUT); // sets the digital pin 7 as output
}

void loop()
{
val = analogRead(analogPin); // read the input pin

digitalWrite(earPin1, HIGH); // sets the earphone on
delay(val/10);
digitalWrite(earPin1, LOW); // sets the earphone on
delay(val/10);

digitalWrite(ledPin2, HIGH); // sets the LED on
delay(val/18);
digitalWrite(ledPin2, LOW); // sets the LED on
delay(val/18);

digitalWrite(ledPin3, HIGH); // sets the LED on
delay(val/20);
digitalWrite(ledPin3, LOW); // sets the LED on
delay(val/20);

digitalWrite(butPin4, HIGH); // sets the button on
delay(val/10);
digitalWrite(butPin4, LOW); // sets the button on
delay(val/10);

digitalWrite(butPin5, HIGH); // sets the button on
delay(val/40);
digitalWrite(butPin5, LOW); // sets the button on
delay(val/50);

digitalWrite(butPin6, HIGH); // sets the button on
delay(val/40);
digitalWrite(butPin6, LOW); // sets the button on
delay(val/40);

digitalWrite(butPin7, HIGH); // sets the button on
delay(val/25);
