How to Create OFF Delay Timer in Arduino ||OFF Delay timer without disturbing program Urdu||Hindi

[@NREnterprises777]

Thank you 💐💐

[@santidebroy2654]

It's very nice. Thank u for it.
But sir I need in thise little bit change....
I want when button released second will be zero but timer will start without button released.

[@AESGreenPlant]

Thanks for this important timer design.

This what exactly I was looking but instead of press button I want use digital read , like if the water level reached high the buzzer will on for 10 seconds plz tell me what changes I hv to do

​​@Automation House why when the switch is in the high position the timer keeps going on and off the LED? does the reset function not work?

[@automationhouse8613]

Yes dear the rest of code will be stay in working seimulteneusly... program will not be stuck in timer code

[@shogunvanrepi3555]

@@automationhouse8613 but in your video when the switch button is pressed for a long time the led will light up and when released the timer will start counting again in other words the switch button functions as a reset button. But when i tried it, it didn't work. Please your solution

@@automationhouse8613 I don't use a switch/push button as an input, but make a connection from +5V pin to digital pin no. 5, does this have any effect?

Sir below is my code for automatically water level indicator using ultrasonic sensor but I want to add buzzer if the water reaches full tank for 10 seconds then it the buzzer should stop

Hi dear what will the code if button is pressed or high and LED will be high again this LED will off while switch is on ,

[@automationhouse8613]

Just read the status of led through digitalRead command and change the state at rising edge while pressing the input...

[@ObaidullahKakar]

@@automationhouse8613 actually I am working on Bluetooth remote here where I have to give the command for bulb to become on but i need this bulb should off after 3 seconds, like for car porch
No need to to make it off by pressing another button ,
Simply auto off bulb after Bluetooth on

[@automationhouse8613]

@@ObaidullahKakar then u should use timer to make it auto off after 3sec
