I know i should learn and make myself the code, but i need this working by the end of this month, so, i pray for anyone that could look to the code and change it to work the same way but with a LCDkeypas instead of a typical LCD, it would really help me guys, and i promise i will learn when i got time.

Well is something like that

Bruno Cunha

Well that remains a problem, the relay keeps turning in and off even if i dont press the button...

Bruno Cunha


int potPin = A1;
const int buttonPin = A2;

void setup() {
Serial.begin(9600);
pinMode(ledPin, OUTPUT);

pinMode(buttonPin, INPUT);

}

void loop()
{
int buttonState = digitalRead(buttonPin);

int val = analogRead(potPin);
long tempo = (val*19.550342131);
Serial.print(tempo);
Serial.print("tempo:");

// read the value from the sensor
if (buttonState==HIGH) {

digitalWrite(ledPin, HIGH);
delay(tempo);
digitalWrite(ledPin, LOW);
} else {}; // turn the ledPin off

delay(500);
}

Like this

Hi,´
I have this timer, where when a button is pressed it activates a relay for some time, the duration is regulated by a potenciometer.

int potPin = A1;
const int buttonPin = A2;

void setup() {
Serial.begin(9600);
pinMode(ledPin, OUTPUT);

pinMode(buttonPin, INPUT);

}

void loop()
{
int buttonState = digitalRead(buttonPin);

int val = analogRead(potPin);
long tempo = (val*19.550342131);
Serial.print(tempo);
Serial.print("tempo:");

// read the value from the sensor
if (buttonState==HIGH) {

digitalWrite(ledPin, HIGH);
delay(tempo);
digitalWrite(ledPin, LOW);
} else {}; // turn the ledPin off

delay(500);
}

Thats the code, my problem is that when i press de button, the arduino stops reading the code while it is counting, can anyone show me a way to keep running the code, but counting the time?
Thank you

Bruno Cunha

Hi, i have this project where i control the the time (0-20 s) that a relay is actuated, i have a button to turn the relay and i want another button to turn off the relay in any moment, like a emergencie button. I though about running a parallel program but i dont know if it possible, here is the code.

"
int potPin = A0;
int ledPin = 13;
const int buttonPin = 2;

void setup() {
Serial.begin(9600);
pinMode(ledPin, OUTPUT);

pinMode(buttonPin, INPUT);

}

void loop()
{
int buttonState = digitalRead(buttonPin);

int val = analogRead(potPin);
long tempo = (val*19.550342131);
Serial.print(val);
Serial.print("tempo:");

// read the value from the sensor
if (buttonState==HIGH) {

digitalWrite(ledPin, HIGH);
delay(tempo);
digitalWrite(ledPin, LOW);
} else {}; // turn the ledPin off

delay(500);
}
"

Well i need to finish this Project until the end of this month so o dont have time to learn, im learning arduino but slower, i dont want a magic code just nisto way of programing the switch buttons to change the time, or where tofind

Bruno Cunha

Hi,
I´m on a irrigation system and i´m using a ds3132 module and a LCD keypad, well i searched a lot and i didnt find a way to change de hour using the switch buttons, for example, i have de lcd showing 6 am as the time it start to irrigate i want to be able to change that hour, so i dont need to disturb the code. I dont really know programing so that´s my problem, please help, thank you for your time.

Bruno Cunha

Yes it worked, i tried something similar before but i did "celsiusA -5" i didnt know i need a variable.I think its solved, thank you very much :)))

Bruno Cunha

celsius1 is the value read by the sensor anda cesliusA is the value regulated by the potenciometer. One question, what is the purpose of the "#define HYSTERESIS 5"?

Bruno Cunha

Hi, so im trying to make a a project with the arduino, where i have this:
-Potenciometer
-temperature sensor
-Relay

So the goal is to read the temperature of something that is heating and turn that off at a certain value that is regulated with the potenciometer.This Is simple , but i want to do something like turn off at 100ºC and only turn that on again at 95ºC. How can you help me? This is the code:

// Relé ligado ao pino 7

int porta_rele1 = 7;
//Relé ligado ao pino 8
int porta_rele2 = 8;

float celsius;
const int porta_sensor1 = A0; // sonda 1 ligada ao pino AO
const int porta_sensor2 = A2; // sonda 2 ligada ao pino A1
const int porta_pot1 = A1; // potenciometro 1 ligada ao pino AO
const int porta_pot2 = A3; // potenciometro 2 ligada ao pino AO

void setup()
{
//Define pinos para o rele como saida
pinMode(porta_rele1, OUTPUT);
pinMode(porta_rele2, OUTPUT);
//Define pinos dos sensores como entrada
pinMode(porta_pot1, INPUT);
pinMode(porta_pot2, INPUT);
pinMode(porta_sensor1, INPUT);
pinMode(porta_sensor2, INPUT);
//Estado inicial dos reles - desligados
digitalWrite(porta_rele1, LOW);
digitalWrite(porta_rele2, LOW);

analogReference(INTERNAL);
Serial.begin(9600);

Serial.begin(9600);
pinMode(porta_pot1, INPUT);
pinMode(porta_sensor1, INPUT);
pinMode(porta_pot2, OUTPUT);
pinMode(porta_sensor2, OUTPUT);
}

void loop()
{
int value1 = analogRead(porta_sensor1); //valor lido na sonda 1
long celsius1 = value1/9.31;
int value2 = analogRead(porta_sensor1); //valor lido na sonda 2
long celsius2 = value2/9.31;
Serial.print(celsius1);
Serial.print(celsius2);

int valueA = analogRead(porta_pot1);
int valueB = analogRead(porta_pot2);

long celsiusA = valueA/9.31; // 10 mV por graus C.
Serial.print(celsiusA);
long celsiusB = valueB/9.31; // 10 mV por graus C.
Serial.print(celsiusB);

if(celsius1 <= celsiusA)
{

digitalWrite(porta_sensor1, HIGH); // aquecedor no pino 9

}
else
{

digitalWrite(porta_sensor1, LOW); // aquecedor no pino 9

}
