Aux air regulator prototype Options

Well, it works on my desk and it works on 12v. Might get around to trying it in the car today.

Here are my routines so far. Anybody think of any other things I can try to address with the AAR? The temp sensor is ambient temp, about 3 or 4 inches from the block.

#define ADC_VREF_mV 5000.0 // in millivolt
#define ADC_RESOLUTION 6000.0
#define PIN_LM35 A0
// constants won't change
const int RELAY_PIN = D8; // the Arduino pin, which connects to the IN pin of relay

void setup() {
Serial.begin(9600);
// initialize digital pin as an output.
pinMode(RELAY_PIN, OUTPUT);

// get the ADC value from the temperature sensor
int adcVal = analogRead(PIN_LM35);
// convert the ADC value to voltage in millivolt
float milliVolt = adcVal * (ADC_VREF_mV / ADC_RESOLUTION);
// convert the voltage to the temperature in Celsius
float tempC = milliVolt / 10;
// convert the Celsius to Fahrenheit
float tempF = tempC * 9 / 5 + 32;

//High idle for ~4 seconds on every start up. delay is how long to wait before moving to the next instruction. Delay is in milliseconds
digitalWrite(RELAY_PIN, HIGH);
delay(4000);

//Hot start routine to address low idle when restarting hot
//will probably need to move that temp around to get this right
if (tempF >99){
delay(10000); //hotstart 10 second additional high idle
digitalWrite(RELAY_PIN, LOW);
}

//Warm start routine
if (tempF <90 and tempF >70){
digitalWrite(RELAY_PIN, HIGH);
delay(60000);
digitalWrite(RELAY_PIN, LOW);
}

//Cool start routine
if (tempF <70 and tempF >50){
digitalWrite(RELAY_PIN, HIGH);
delay(120000);
digitalWrite(RELAY_PIN, LOW);
}

//Cold start routine
if (tempF <50) {
digitalWrite(RELAY_PIN, HIGH);
delay(240000);
digitalWrite(RELAY_PIN, LOW);
}
}

void loop() {}
