As I told before: https://github.com/FernandoGarcia/Ferdu ... a.ino#L207

A prototype shield or screw shield is needed to connect all devices.

from arduino mega board
the pins for led

Code: Select all

const byte ledPinUV = 8;         // Pino que liga os leds violeta
const byte ledPinBlue = 9;       // Pino que liga os leds azuis
const byte ledPinWhite = 10;     // Pino que liga os leds brancos
const byte ledPinRoyBlue = 11;   // Pino que liga os leds "royal blue"
const byte ledPinRed = 12;   

and for timer1 2 3 etc?

can i work timers without PCF8575?

Yes, only swap the pin numbers with a free pin in your system.

If you won't use wavemaker you can make like this:

Code: Select all

const byte temporizador1 = 80;
const byte temporizador2 = 81;

const byte wavemaker1 = 45;
const byte wavemaker2 = 46;


Change to:

Code: Select all

const byte temporizador1 = 45;
const byte temporizador2 = 46;

const byte wavemaker1 = 80;
const byte wavemaker2 = 81;


In your case the pin 7 is free too so you can make like this:

Code: Select all

const byte temporizador3 = 7;

hi fernando again...

Hi!

What's your problem?

The posts above are not clear?

Best regards.

in lines

Code: Select all

const byte temporizador1 = 5;       // P5       // Pin that turns on the timer 1.
const byte temporizador2 = 6;       // P6       // Pin that turns on the timer 2.
const byte temporizador3 = 7;       // P7       // Pin that turns on the timer 3.
const byte temporizador4 = 8;       // P8       // Pin that turns on the timer 4.
const byte temporizador5 = 9;       // P9       // Pin that turns on the timer 5.

i change the pins

Code: Select all

const byte temporizador1 = A5;       // P5       // Pin that turns on the timer 1.
const byte temporizador2 = A6;       // P6       // Pin that turns on the timer 2.
const byte temporizador3 = A7;       // P7       // Pin that turns on the timer 3.
const byte temporizador4 = A8;       // P8       // Pin that turns on the timer 4.
const byte temporizador5 = A9;       // P9       // Pin that turns on the timer 5.

are that correct? and the old pins a5 a6 a7 a8 a9 i change with these 5 6 7 8 9 ?

Which part of this text you don't understand?

Code: Select all

//****************************************************************************************************

// Do not change this part if you have not a PCF8575 installed.


You should change this part according to what I told above.

Code: Select all

const byte temporizador1 = 80;           // Pino que liga o timer 1.
const byte temporizador2 = 81;           // Pino que liga o timer 2.
const byte temporizador3 = 82;           // Pino que liga o timer 3.
const byte temporizador4 = 83;           // Pino que liga o timer 4.
const byte temporizador5 = 84;           // Pino que liga o timer 5.
const byte solenoide1Pin = 85;           // Liga a reposicao de água doce.
const byte alimentadorPin = 86;          // Pino que controla o alimentador automático.
const byte skimmerPin = 87;              // Pino que controla o skimmer
