Here the code below I am dealing with ESP 8266 & a DF Player is for the analog input triggering purpose But here when I use to trigger the A0 input in series with a resistor value via earth line It simply starts triggering the file repeatedly with a very high triggering speed Unless and until I r…

Try the https://docs.arduino.cc/built-in-examples/digital/StateChangeDetection/ example and replace "on" with "E": /* State change detection (edge detection) --Altered to print "E" instead of "on" Often, you don't need to know the state of a digital input all the time, but you just need …

Ya this is for digital pin and I worked already on it But same thing I want to have for analog input in case of DF Player only. The reason I mentioned, where it triggers the audio file with high speed repeatedly That is the only matter !!!!!

[image] King_RAJ_Enters: But same thing I want to have for analog input... Here's the same thing adapted to do a threshold on an analog input: /* State change detection (edge detection) --Altered to print "E" instead of "on" --And with a 512 threshold applied to an analogRead(A0) …

OK done ! Now I want to remove the operation which is happening while we are releasing the push button That I want to remove or omit completely Just the press of push button ll be there As I have to merge the code with DF player So if it ll trigger twice like this then surely it ll trigger a f…

[image] King_RAJ_Enters: Now I want to remove the operation which is happening while we are releasing the push button Good luck!

A function something like this (derived from your very last code) const int buttonPin = A0; // the pin that the pushbutton is attached to const int ledPin = 13; // the pin that the LED is attached to // Variables will change: int buttonPushCounter = 0; // counter for the number of button pre…

@King_RAJ_Enters does not say, but the destination of the journey seems to be using a kludge, or a kluge, of resistors forming a voltage divider in order to develop N number of button ~~states~~ pressed events.

For any who will help him, I suggest the AceButton library, and an article there outlining the steps to take for using a resistive ladder.

I am reminded of the great thread that put some light onto use of the ESP a/d convertor in the context of voltage divider multiple buttons:

HTH anyone helping the King.
