How to make a Heating and Cooling Jacket

Step 15 Code

You will need to test out your circuit with the code to make sure you have it working before you put it all in. This code should run both of the circuit switches; you will have to modify it to run just one system at a time. For help on this you can look on the Arduino website.


int ledPin = 13; // LED is connected to digital pin 13
int sensorPin0 = 0; // temperature sensor is connected to analog pin 0
int sensorValue0; // variable to store the value coming from sensor a0
int sensorPin1 = 1; // temperature sensor is connected to analog pin 1
int sensorValue1; // variable to store the value coming from sensor a1
int sensorPin2 = 2; // temperature sensor is connected to analog pin a2
int sensorValue2; // variable to store the value coming from sensor a2
int sensorPin3 = 3; // temperature sensor is connected to analog pin 3
int sensorValue3; // variable to store the value coming from sensor a3
int sensorPin4 = 4; // temperature sensor is connected to analog pin 4
int sensorValue4; // variable to store the value coming from sensor a4
int sensorPin5 = 5; // temperature sensor is connected to analog pin 5
int sensorValue5; // variable to store the value coming from sensor a5
int fanRelay = 7; // fan relay is connected to digital pin 7
int heatRelay = 3; // heating coil relay is connected to digital pin 6

// Output

int greenPin = 9; // Green LED, connected to digital pin 10
int bluePin = 10; // Blue LED, connected to digital pin 11
int redPin = 11; // Red LED, connected to digital pin 9


// Program variables
int redVal = 255; // Variables to store the values to send to the pins
int greenVal = 0; // Initial values are Red full, Green and Blue off
int blueVal = 0;



void setup()
{
pinMode(ledPin, OUTPUT); // sets the ledPin to be an output
Serial.begin(9600); // initialize the serial port
digitalWrite(ledPin, HIGH); // turn the LED on
pinMode(redPin, OUTPUT); // sets the pins as output
pinMode(greenPin, OUTPUT);
pinMode(bluePin, OUTPUT);
pinMode(fanRelay, OUTPUT);
pinMode(heatRelay, OUTPUT);
digitalWrite(fanRelay, LOW); // sets fan relay to off
digitalWrite(heatRelay, LOW); // sets heat coil relay to off

}

void loop() // run over and over again
{

Serial.println("Sensor Values:");
sensorValue0 = analogRead(sensorPin0); // read the value from the sensor
Serial.println(sensorValue0); // send that value to the computer
sensorValue1 = analogRead(sensorPin1); // read the value from the sensor
Serial.println(sensorValue1); // send that value to the computer
sensorValue2 = analogRead(sensorPin2); // read the value from the sensor
Serial.println(sensorValue2); // send that value to the computer
sensorValue3 = analogRead(sensorPin3); // read the value from the sensor
Serial.println(sensorValue3); // send that value to the computer
sensorValue4 = analogRead(sensorPin4); // read the value from the sensor
Serial.println(sensorValue4); // send that value to the computer
sensorValue5 = analogRead(sensorPin5); // read the value from the sensor
Serial.println(sensorValue5); // send that value to the computer


int sensorAverage = (sensorValue0+sensorValue1+sensorValue2+sensorValue3+sensorValue4+sensorValue5)/6; // average the sensor values


if (sensorValue0 < 215) // cold phase of fades
{
if (redVal < 255) redVal +=15; // Red down
if (blueVal > 0) blueVal -=15; // Blue up

}
else if (sensorValue0 > 215) // warm phase of fades
{
if (redVal > 0) redVal -=15; // Red up
if (blueVal < 255) blueVal +=15; // Blue down
}
if (sensorValue0 < 215) // active cold phase
{
digitalWrite(heatRelay, HIGH); // activate heat
digitalWrite(fanRelay, LOW); // deactivate fans
delay(2000); // wait

}
if (sensorValue0 > 215) // active warm phase
{
digitalWrite(heatRelay, LOW); // deactivate heat
digitalWrite(fanRelay, HIGH); // activate cold
delay(2000); // wait

}


//Debug

Serial.println("Sensor Average:"); // send that value to the computer
Serial.println(sensorAverage); // send that value to the computer
Serial.println("Check Color Value:");
Serial.println(redVal);
Serial.println(blueVal);



analogWrite(redPin, redVal); // Write current values to LED pins
analogWrite(greenPin, greenVal);
analogWrite(bluePin, blueVal);
