Delay output

Projects General Guidance
1

Good day! I would like to ask some help and guidance in making our project work.

our project is composed of 5 PIR sensors which are connected to pin 0 to 4 and pin 8 to 12 as output.
The idea is when a sensor detects movement the output will be delayed for a certain period of time.
For example, if sensor1 detected motion, output1 will "on" after 5 seconds.

The problem I'm getting my code is during this scenario:

i set the delay for 5 seconds. Then I triggered 1 sensor, then after 3 seconds I triggered another. The output delay with the first sensor is working but for the other sensor it seems it inherited the delay of the first sensor. What happened is both output turned on after 5 seconds. The second output suppose to turn on after 3 seconds after the output of the 1st sensor.

Here is my code

long runtime,Tdiff,prev = 0;

char set[32] ={

0x00,
0x01,
0x02,
0x03,
0x04,
0x05,
0x06,
0x07,
0x08,
0x09,
0x0A,
0x0B,
0x0C,
0x0D,
0x0E,
0x0F,
0x10,
0x11,
0x12,
0x13,
0x14,
0x15,
0x16,
0x17,
0x18,
0x19,
0x1A,
0x1B,
0x1C,
0x1D,
0x1E,
0x1F

};

int count = 0;

void setup() {

for(int ledPin1 = 0; ledPin1 <5; ++ledPin1){
pinMode(ledPin1, INPUT);

}

for(int ledPin = 8; ledPin <13; ++ledPin){
pinMode(ledPin, OUTPUT);
}

}

void loop() {

for(int x = 0x00; x <=31; x++){

if(PIND >= x ){
bilang();
if(count >=5){
count = 0;

PORTB = ~set[ x ];

}
}

}

}

void bilang()

{

runtime = millis();
Tdiff = runtime-prev;
if (Tdiff>1000)
{
count++;
prev = runtime;

}

}

sorry for the long post :drooling_face:

thank you :smiley:

sorry for the long post

If you would have bothered to read the "how to use this forum" sticky post you would have seen how to post the code correctly.
Never mind read it and modify your original post.

Second, do not use pins 0 & 1 because there are used for serial communications like uploading code.

Third, what you are trying to do is known as a state machine. It is not a thing for beginners as they find it complicated. However it is easy enough to understand. You need to remove all delays, because these are blocking and use the technique shown in the blink without delay example in the IDE.

The demo several things at a time shows how to manage different times using the BWoD technique.
