Thank You so much ! Best gift for Christmas

Nice Video!
Can i buy a timer like this, which is working with a battery and a button? I just need a countdown going down from 15 minutes each time the button is pressed.

Is it possible to add a tick to this program? The only ones that I have seen use a delay.

How can I start stop and reset it from a node red dashboard

At 8:22 You say if you want something to happen at the end of the countdown you can place it in the loop function but the loop function in your video is outside the frame so where should it be placed? xD I have tried a few options but it never plays at the end, it just resets.

thank you good sir. you remind me that unsigned long exist :D so i've been trying to make a timer with 8 hours but fail since i declare it as int >< but watching you inspire me hahaha thank you really :)

Great video mate, I was looking for something like this. Also if use that code in a "bomb type puzzle case" how would you change the code to subtract 5 mins from the clock for a "wrong" input (not completing understanding Arduino code yet). Any help would be great. Thanks.

[scjewell]

The unsigned long variable timeRemaining has to be long. An unsigned long never becomes negative and timeRemaining always remains positive, meaning you can't break out of the countdown loop. This is the answer to the questions below as to how to stop the time.

Just How do I make a beeper sound when the time is over? some help

Is the code possible to be used on a 4 digit led strip made clock/timer?

[davidmora]

Hi Sr. nice video and well explained, can you add to the timer a 4x4 Keypad to choose the time that I want? and how to do it? I study electronic 20 year ago, so I just started with Arduino, but has been so hard to understand things, I'm not. programming person, so can you help me with that?

[gangadhars]

Hello Sir.. I am new to Arduino, I am planning to do project which will glow the light when the timer reaches 0 and I want this to be done for one your clock which is 31536000 seconds to 0 seconds.. need your input.

Nope, the original countdown works, but the adjustments in code for the minute/sec countdown produces no display, although the code did compile - same hardware setup for the 5000 second countrdown

Hi there!
Thank you for the video and the explanation!
Some why, my separator is ":" not showing
