Street Lighting System

ashishpandey · February 14, 2018, 1:56pm

I have implemented a model for smart street lighting. All things are working fine. Just a small issue i found in my model. I have set a delay of 3 secs for LED's. So what happen is If a vehicle passes through first IR sensor and it glow 2 or 3 lights. When vehicle goes through the next IR sensor, It first waits for 3 seconds to over for IR1 and then glow the lights. Hope you have understood what i want to say? So my question is how i can avoid this issue?

I'm sure you can fix this by making changes to your (unspecified) IR sensors or in your (unposted) code.

Don't use delay(). Use the blink without delay method for timing. Then your code won't block and will be responsive.

Why no code tags?

What code tags? Can you explain as i am new here.

You you can lookup the code. Any modifications on that?

wvmarle · February 14, 2018, 2:42pm

Several delay(2000) calls there. That is a prime candidate for the problems you described. Get rid of those, use millis() based timing instead (see the Blink Without Delay example).

ashishpandey · February 14, 2018, 4:07pm

Can you explain me where to use the conditions for mills as i am not getting where to use it

ashishpandey · February 14, 2018, 6:07pm

Still i am not getting the correct coding for this. Any more Help ?

ashishpandey · February 14, 2018, 7:06pm

I am using 5 IR sensors. When first IR sensor detects the vehicles 2 LED's should be on. When second IR sensor detects the vehicle 2 respective LED's should be on and so on. But i have set a delay for 3 seconds and because of that LED's takes time to glow because of the previous LED's.. I know this is happening because of the delay. As you guys have suggested to use millis(), I tried to do it but was unable to do. Can anyone suggest me where to use milli() and how can i avoid the delay problem. My sketch is given below:

I had a look on all these posts but believe me for a beginner it is very confusing. I am totally confused where should i use what. Can any one have a look on my sketch and correct it for me

LarryD · February 14, 2018, 7:30pm

  if(isObstacle1 == HIGH)
  {
    Serial.println("OBASTCLE !! at sensor 1");
    digitalWrite(LED2, HIGH);
    delay(3000);
  }

Why do you want to delay for 3 seconds here?

LarryD · February 14, 2018, 7:34pm

When first IR sensor detects . . ..

Detects what, when, how?

Why are you asking for help in another thread?
This not only wastes our time but is very rude!

What is the purpose of each delay() in your sketch?
