Please see the code at the project's page:

im floored that this works as expected. I have been bouncing between so many videos and tutorials lately that are garbage. This works perfectly and right away. Thank you for your effort.

This is a masterclass 😎. You explain everything, which is very useful for a beginner like me, your explanations are clear, your code is clear etc... It's the best tutorial on Youtube to do this project, and I'm really happy to have found it : ) (I had spent one hour to try to understand other tutorials ...)
Thank you so much : )

Thank you so much for the upload! The YouTube community has many sharp, knowledgeable, and creative minds that bails out a shulb like myself 😅

thanks for this, now i created my version of this instead of start reset up down button
..i made the start/stop ..anytime you want to stop the count it will stay the same number and thats the only time you can reset the counter...
if the counter running no button will function aside from the start/stop button...

Hello sir! Quick question, Where should I connect the buttons if im using an arduino UNO?

[itzelon]

This is great!! Thank you for uploading, your code was really useful 🙏

great project for board games by time, one question is the display of the segments is common anode or cathode? .Another question, is it possible to change pins 16 and 17 to pins 0 and 1 of an arduino and change pin 15 speaker to an analog pin ?, if we change it in the code? I want to make a timer for board games that need some time to perform the goal and use an arduino nano, thanks friend

this looks amazing, trying to get the best of my arduino and will definetely try this later, I hope it works!

[bryanh]

Great video it was very helpfull to get me started with arduino

[tripsgame]

I used Common Cathode 7s. It worked. Thankyou!

[djnava]

on the display the first digit lights up slightly, how can it be solved? thanks

[kevin]

Can be done with Arduino UNO use pins 1 and 0 for button pins 16 and 17 :)

Hi Dmytro, i stumbled upon this tutorial as this is the sort of project that i am looking for as a begginer. One thing i may ask is how to add a code to Pause the timer with the Start button (or essentialy making it a Start/Pause button)? Looking forward to your reply. Thank you.

in 10:41 i'm also getting the same digits in multiple positions, in my case, it's 3. I wasn't able to understand how that works, like what does he mean by turning digit 1, 2, 3 and 4 on and off? pls help

Awesome build ! is it possible to make it Up and Down counter ? ( you set your time ( ex 60 secs), press UP button or Down button then START it will count from 0 to 60 or 60 to 0 )

[biancorosso]

Hi, It's very useful project.it can use arduino uno?

[mikeramirez]

Not sure if you are still keeping up with this. I wanted to add 30 sec while the timer is counting down when I push the button, will this code work close to what I need? Would greatly appreciated your help.

Thank you, it's really helpful!!
