Dear,
I'm a beginner in the Arduino world, and can't solve a particular issue on my own.
I have a 12V geared motor that operates a slide door. On the door i have 2 microswithes that stops the motor when at the end of the travel and activates a door LED light to indicate the state.
I've used a GREEN LED to indicate that the door is CLOSED and a RED LED to indicate it is OPEN.
I have integrated another LED, which should come on when the door is neither full open or full closed. So, this AMBER led is indicating a TRANSIT situation.
Now, i've been testing around with several IF, Else and IF statements, but i never get it to work like i wish. Whenever the door is in transit, both the GREEN and RED led's should be OFF and the AMBER on. Once at eiher side end-of travel, the AMBER Led should go out, and either the FULL OPEN RED led or the FULL CLOSED GREEN Led should come on.....
My actual code looks like this:
#include <math.h>
#include <Dusk2Dawn.h>
#include <EEPROM.h>
#include <Wire.h>
#include <RTClib.h>
//Define what pins are used
const int doorUpSensorPin = 4; // reedswitch door open
const int doorDownSensorPin = 5; // reedswitch door down
const int doorDownMotorPin = 10; // wind motor down
const int DoorUpMotorPin = 9; // wind motor up
const int builtInLEDRED = 12; // LED indicating door closed (microswitch on pin 5)
const int builtInLEDGREEN = 8; // LED indicating door OPEN ( microswitch on pin 4)
const int transitledAmber = 7; // LED indicating door in TRANSIT ( neither of the microswitches active)
const byte CloseDoorManual = 3; // Close door by hand
int buttonstateclose = 0;
int currentMins;
int sunrise;
int sunset;
DateTime now;
//Are We Debugging?
const bool debug = true;
//Do we need to set/adjust RTC?
const bool setRTC = true;
//Define RTC
RTC_DS1307 rtc;
//define the location / timezone for dusk2dawn (this is yourcity, countrycode 2 digit)
// change yourcity an fill in coordinates and timezone
Dusk2Dawn Kapellen(51.31483014538207, 4.458376022992936,+1);

//Set the mode the pins will operate in.

// //Lets just set the date/time when setRTC = true.
if (setRTC)
{
//write PC date and time while uploading and when setRTC = true
rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
//uncomment line 71 to write date and time manually into RTC when line 38 setRTC = true. For testing sunset/sunrise
//rtc.adjust(DateTime(2020, 7, 23, 7, 9, 20));
}
}

}
// the loop function runs over and over again until power down or reset

if (debug){
Serial.println();
Serial.println("SERVO LOOP");
}
//Get the Date/Time from the RTC
now = rtc.now();
//Get Sunrise/Sunset for the current year/month/day as INT's that equate to minutes from midnight that he sunrise/sunset will occur (THE TRUE is passing in Daylight Savings Time!)
sunrise = Kapellen.sunrise(now.year(), now.month(), now.day(), true);

//lets start comparisons, if the door should be up....
//delay of 30 minutes after sunset time to make sure all chickens are inside before closing the door.

}
}
//Wind The Door Down
void lowerDoor() {
digitalWrite(doorDownMotorPin, HIGH);
digitalWrite(DoorUpMotorPin, LOW);
if (debug) {
Serial.println("Door moving DOWN");
stopDoor();
}
}
//Stop the Door
void stopDoor() {
digitalWrite(DoorUpMotorPin, LOW);
digitalWrite(doorDownMotorPin, LOW);
if (debug) {
Serial.println("Door Stop");
}
}
//Close door manual
void ManualClose() {
digitalWrite(doorDownMotorPin, HIGH);
digitalWrite(DoorUpMotorPin, LOW);
if (debug) {
Serial.println("Door Closing Manual");
while ( digitalRead(doorDownSensorPin) == LOW)
digitalWrite(transitledAmber, HIGH);
stopDoor();
}
}
What do i need to do, to get it work???
ps, there's also a manual override switch, that allows me to CLOSE the door manually....
Thanks in advance for the tips and help.
