Change pins for dosing pumps

[Norberto Pinheiro]

Hello Fernando,
I wish all is well with you

I need to change analog pins to digital pins for dosing pumps.

if I change this:

Code: Select all

const int dosadora1 = A9;      // Bomba dosadora 1
    const int dosadora2 = A10;     // Bomba dosadora 2
    const int dosadora3 = A11;     // Bomba dosadora 3
    const int dosadora4 = A12;     // Bomba dosadora 4
    const int dosadora5 = A13;     // Bomba dosadora 5
    const int dosadora6 = A14;     // Bomba dosadora 6

for this:

Code: Select all

**************** PCF8575TS **********************************
    const int dosadora1 = 1;      // Bomba dosadora 1
    const int dosadora2 = 2;     // Bomba dosadora 2
    const int dosadora3 = 3;     // Bomba dosadora 3
    const int dosadora4 = 4;     // Bomba dosadora 4
    const int dosadora5 = 5;     // Bomba dosadora 5
    const int dosadora6 = 6;     // Bomba dosadora 6


all of this:

Code: Select all

digitalWrite(dosadora1, HIGH);

for this:

Code: Select all

PCF8575TS.digitalWrite(dosadora1, HIGH);

and everything like this:

Code: Select all

 (analogRead(sensor1)<400)


for something like this:

Code: Select all

(analogRead(sensor1)==LOW)


everything will work?

sorry my English
thanks in advance

Hi!

Firstly the best way to know if a code is fine is sending to board and test it.

If you have changed the setup as explained here should be right.

Remember that pin numbers for PCF8575 goes of 0 up to 15.

Regarding analog pins check it: http://arduino.cc/en/Reference/AnalogRead

Best regards.
