Hello
I'm trying to make a simple program using Arduino UNO that controls a slide door
It's very simple containing the following steps :
A sensor which should give 5v when motion detected then the door must open until receiving a 5v from another sensor called (endopen) then it will close until receiving a 5v from another sensor called (endclose)
But I'm having problems using While and If statements, the door must remain opening whenever (sensor) value is HIGH
The following code cause the both (opendoor) and (closedoor) remain HIGH even without (sensor) high value:
int opendoor = 2;
int closedoor = 3;
int endopen = 4;
int endclose = 5;
int manopen = 6;
int manclose = 7;
int sensor = 8;
void setup()
{
pinMode(opendoor, OUTPUT);
pinMode(closedoor, OUTPUT);
pinMode(endclose, INPUT);
pinMode(endopen, INPUT);
pinMode(sensor, INPUT);
pinMode(manopen, INPUT);
pinMode(manclose, INPUT);
digitalWrite(opendoor,LOW);
digitalWrite(closedoor,LOW);
Serial.begin(9600); //begins serial communication
}
void loop() {
digitalWrite(opendoor,LOW);
digitalWrite(closedoor,LOW);
if (digitalRead(sensor) == HIGH ) {
do
{
digitalWrite(opendoor,HIGH);
digitalWrite(closedoor,LOW);
Serial.print("Opening");
}
while ((endopen) == LOW);
}
else if (digitalRead(endopen) == HIGH)
{
do
{
digitalWrite(opendoor,LOW);
digitalWrite(closedoor,HIGH);
Serial.print("---Closing----");
}
while ((endclose) == LOW);
}
else if (digitalRead(endclose) == HIGH)
{
digitalWrite(opendoor,LOW);
digitalWrite(closedoor,LOW);
Serial.print("---Closing----");
}
else
digitalWrite(opendoor,LOW);
digitalWrite(closedoor,LOW);
}
I'm beginner at programming ... Excuse me
thanks in advance
