I Used 9 LED to blink on and off delay(100ms) in arduino nano, and i attached two Digital Input pin to my arduino nano (D11, D12)
I am using Blynk app to send the signals into Digital Input Pin to arduino , BUT When i send the off signal to the Digital input pins , the Loop doesnt End Instantly *They wait for the Whole loop and then its end *
BUT i want , when i will send the LOW signal to the output the loop will end instantly
please help me ...... get me enlightened
if it is an iteration loop such as while or for you can use
break;
if it is loop() function you can use
return;
thanks for your reply , i am new in arduino , can you help me to put "return" in correct place in the source code , here is my code ...
//From ESP8266 we will run 10 LED
int digiPin = 11;
int digiPin2 = 12;
int ledPin = 2;

int ledPin7 = 8;
int ledPin8 = 9;
int ledPin9 = 10;
// select the pin for the LED
int pinVal = 0;
int pinVal2 = 0;

The problem are that many delays in your sketch. Your input pin is only read once in the loop after all the blinking is done.
You must rewrite your sketch without delays. See the example 'BlinkWithoutDelay'. Or you can use a library with time-functions, which maybe a little bit easier
Use millis() for timing instead of delay() to avoid the code blocking waiting for the delay()s during which it can do nothing else
See Using millis() for timing. A beginners guide - Introductory Tutorials - Arduino Forum and Demonstration code for several things at the same time - Project Guidance - Arduino Forum and the BlinkWithoutDelay example
Hello
I have read your sketch to understand what your intention is.
I think you would like to have a gallery of flash lights controlled by the the input switches digiPin and digiPin2. That will not work in all cases the
else {
digitalWrite(ledPin , LOW);
digitalWrite(ledPin2 , LOW);
digitalWrite(ledPin3 , LOW);
digitalWrite(ledPin4 , LOW);
digitalWrite(ledPin5 , LOW);
digitalWrite(ledPin6 , LOW);
digitalWrite(ledPin7 , LOW);
digitalWrite(ledPin8 , LOW);
digitalWrite(ledPin9 , LOW);
}
will inhibit all other LED actions.
Well I think a collection of timers and a small FSM will be a proper start point to do this job.
One quick and dirty option is to write a 'myDelay()' function that checks the button while waiting for time to expire. If the button is pressed, have it return 'true'. If the time expires, have it reurn 'false'. Then, in your code, replace "delay(100);" with
if (myDelay(100)) return;
The 'return;' statement will exit from loop() which will then be called again and will detect that the button is pressed.
bool myDelay(unsigned long delayTime)
{
unsigned long startTime = millis();
while (millis() - startTime <= delayTime)
{
if (digitalRead(digiPin) == LOW)
return true;
}
return false;
}
One man's quick and dirty is another's clever.

Thank You So MUCH
in which part i will put this code ???
Like I said:
What part of that did you not understand?
