Controlling LEDs with 4 ultra sonic sensors

Other Hardware Sensors

Hi there,

I managed to solve that problem that i had before but have managed to get myslef into a silly situation: I am now at a gallery installing my work and I have not sorted out the problems with the code that I had before I made my sculpture itself! Too much to think about I think!

So I could really use some help!

The code

#include "Wire.h"
#include "SRF02.h"

SRF02 srf02[4] = { 
  SRF02(0x70, SRF02_CENTIMETERS),
  SRF02(0x71, SRF02_CENTIMETERS), 
  SRF02(0x72, SRF02_CENTIMETERS),
  SRF02(0x73, SRF02_CENTIMETERS)
};

unsigned long nextPrint = 0;

void setup()
{
  Serial.begin(9600);
  Wire.begin();
}

void loop()
{
  SRF02::update();
  if (millis() > nextPrint)
  {
    Serial.print(srf02[0].read());
      Serial.print(",");
      Serial.print(srf02[1].read());
      Serial.print(",");
      Serial.print(srf02[2].read());
      Serial.print(",");
      Serial.print(srf02[3].read());
      Serial.println();
      nextPrint = millis () + 1000;
}



// When sensor's 70, 71, 72 & 73 take a reading between 0-50 turn on LED strip on port 5.

if (srf02[0].read() >=0 && srf02[0].read() <= 50)
     digitalWrite(5, HIGH);
if (srf02[1].read() >=0 && srf02[1].read() <= 50)
     digitalWrite(5, HIGH);
if (srf02[2].read() >=0 && srf02[2].read() <= 50)
     digitalWrite(5, HIGH);
if (srf02[3].read() >=0 && srf02[3].read() <= 50)
     digitalWrite(5, HIGH);

// When sensor's 70, 71, 72 & 73 take a reading between 50-100, keep on LED strip 5 and also turn on the LED strip on port 6.'

if (srf02[0].read() >=50 && srf02[0].read() <= 100) {
     digitalWrite(5, HIGH);
     digitalWrite(6, HIGH);
}
if (srf02[1].read() >=50 && srf02[1].read() <= 100) {
     digitalWrite(5, HIGH);
     digitalWrite(6, HIGH);
}
if (srf02[2].read() >=50 && srf02[2].read() <= 100) {
     digitalWrite(5, HIGH);
     digitalWrite(6, HIGH);
}
if (srf02[3].read() >=50 && srf02[3].read() <= 100) {
     digitalWrite(5, HIGH);
     digitalWrite(6, HIGH);
}


// I would be happy to have this communication going first but ultimately I actually want 
// the readings to fade in and out my LEDs, see below:

// 'When sensors 70, 71, 72 & 73 take readings 0-50 fade in LED strip on port 5, 0 being the lowest, 50 being the brightest.

if (srf02[0].read() >=0 && srf02[0].read() <= 50)
     analogWrite(4, map(srf02[0].read(), 0, 50, 0, 255));
if (srf02[1].read() >=0 && srf02[1].read() <= 50)
     analogWrite(4, map(srf02[1].read(), 0, 50, 0, 255));
if (srf02[2].read() >=0 && srf02[2].read() <= 50)
     analogWrite(4, map(srf02[2].read(), 0, 50, 0, 255));
if (srf02[3].read() >=0 && srf02[3].read() <= 50)
     analogWrite(4, map(srf02[3].read(), 0, 50, 0, 255));


// When sensors 70, 71, 72 & 73 take readings 50-100, keep strip 5 on its brightest and fade in strip on port 6, 50 beng the lowest, 100 being the brightest.'


if (srf02[0].read() >=50 && srf02[0].read() <= 100) {
     digitalWrite(4, HIGH);
     analogWrite(5, map(srf02[0].read(), 50, 100, 0, 255));
}
if (srf02[1].read() >=50 && srf02[1].read() <= 100) {
     digitalWrite(4, HIGH);
     analogWrite(5, map(srf02[1].read(), 50, 100, 0, 255));
}
if (srf02[2].read() >=50 && srf02[2].read() <= 100) {
     digitalWrite(4, HIGH);
     analogWrite(5, map(srf02[2].read(), 50, 100, 0, 255));
}
if (srf02[3].read() >=50 && srf02[3].read() <= 100) {
     digitalWrite(4, HIGH);
     analogWrite(5
     , map(srf02[3].read(), 50, 100, 0, 255));
 }
}

My problems:

  1. For some reason when the sensors read above 100 the light in port 5 just stays on all the time. I beileve that i need to state in the code when sensors read above 100 keep both lights in ports 5 and 4 off.
  2. The lights don't appear to fade in or out - please can you indicate in the code which bit is that states the fade in and out and how to alter it.
  3. i would also like to know which bit in the code indicates the sensor readings as i may need to tweak these. Please can you point this out to me aswell.

If you or anyone else can help me, I would most appreciate it.

Thankyou,

Aphra
