Today I finished mounting the LEDs that I will use in my installation. I used the Arduino hardware to control the fade in and fade out and the time each LED is illuminated.
Here is the code I´ve used:
int Pin5 = 5; // Led 1
int Pin3 = 3; // Led 5
int Pin9 = 9; // Led 2
int Pin10 = 10; // Led 3
int Pin11 = 11; // Led 4 (the 'wave' goes Led: 1-2-3-4-5)
int Value5 = 0; //Value Led1
int Value3 = 0; //Value Led5
int Value9 = 0; //Value Led2
int Value10 = 0; //Value Led3
int Value11 = 0; //Value Led4
int analog0Pin = 0; // button to start wave
int val0 = 0; // variable to store the value read
int threshold = 512; // threshold for button
int timer = 100;
void setup()
{
pinMode(analog0Pin, INPUT);
pinMode(Pin5, OUTPUT); // sets the digital pin as output
pinMode(Pin3, OUTPUT); // sets the digital pin as output
pinMode(Pin9, OUTPUT); // sets the digital pin as output
pinMode(Pin10, OUTPUT); // sets the digital pin as output
pinMode(Pin11, OUTPUT); // sets the digital pin as output
Serial.begin(9600); // setup serial
}
void loop()
{
val0 = analogRead(analog0Pin); // read the input pin for button
Serial.println(val0); // debug value
if (val0 >= threshold) //
{
for(Value5 = 0 ; Value5 <= 255; Value5+=5) // fade in (from min to max) Led 1
{
analogWrite(Pin5, Value5); // sets the value (range from 0 to 255)
delay(30); // waits for 30 milli seconds to see the dimming effect
}
for(Value5 = 255; Value5 >=0; Value5-=5) // fade out (from max to min)
{
analogWrite(Pin5, Value5);
delay(30);
}
if (Value5 = 255) //
{
for(Value9 = 0 ; Value9 <= 255; Value9+=5) // fade in (from min to max) Led 2
{
analogWrite(Pin9, Value9); // sets the value (range from 0 to 255)
delay(30); // waits for 30 milli seconds to see the dimming effect
}
for(Value9 = 255; Value9 >=0; Value9-=5) // fade out (from max to min)
{
analogWrite(Pin9, Value9);
delay(30);
}
if (Value9 = 255) //
{
for(Value10 = 0 ; Value10 <= 255; Value10+=5) // fade in (from min to max) Led 3
{
analogWrite(Pin10, Value10); // sets the value (range from 0 to 255)
delay(30); // waits for 30 milli seconds to see the dimming effect
}
for(Value10 = 255; Value10 >=0; Value10-=5) // fade out (from max to min)
{
analogWrite(Pin10, Value10);
delay(30);
}
}
if (Value10 = 255) //
{
for(Value11 = 0 ; Value11 <= 255; Value11+=5) // fade in (from min to max) Led 4
{
analogWrite(Pin11, Value11); // sets the value (range from 0 to 255)
delay(30); // waits for 30 milli seconds to see the dimming effect
}
for(Value11 = 255; Value11 >=0; Value11-=5) // fade out (from max to min)
{
analogWrite(Pin11, Value11);
delay(30);
}
}
if (Value11 = 255) //
{
for(Value3 = 0 ; Value3 <= 255; Value3+=5) // fade in (from min to max) Led 5
{
analogWrite(Pin3, Value3); // sets the value (range from 0 to 255)
delay(30); // waits for 30 milli seconds to see the dimming effect
}
for(Value3 = 255; Value3 >=0; Value3-=5) // fade out (from max to min)
{
analogWrite(Pin3, Value3);
delay(30);
}
}
}
}
}
