Very nice tutorial! I want to build a digital clock which synchronizes to internet time. Not sure where to start. I love your large displays. I want to add the colon (two dots) between the pairs of digits. Maybe display seconds, although extra work and cost probably is not worth it.
This is the Video I've been looking for. I want to use this as a count down timer for our Archer Club, but I need to set the time in minuites and seconds. for example if I need 4:10sec. Can it do that. Also when the count down timmer reaches 30Seconds I want to turn the LEDs colour yellow and when it reaches 0 mins. I want it to turen Red. Thanks for sharing.
Hi! I've a similar project in mind, just wondering: how many led/meter did you take? 30led/m, right? what power supply did you use to work with that much leds? In my case I would need to have 3 digits for hours, 2 digits for minutes and 2 for seconds(so 7 total), if I use like segment of 14 cm/segment, 7 segment/digit, it's something around 686cm. If I check my WS2812B provider, it's 9w/meter, so something around 63W. With a 5V tension, it implies something around 13A, which seems enormous. Did you had similar issues?
Hi Alistair, awesome tutorial video! My son (14) would like to make a two digit LED board with 8" sized digits. He would like to make it portable, so needs to have a rechargeable 5V LiPo battery. Could you provide some recommendations or advice for him? Thanks, Andrew
Thanks for your great tutorial. I built my own 7-segment display following your instructions. Unfortunately, the timer always stops counting - at different times, sometimes at 1 minute 13 seconds, sometimes at 3 minutes and then starts again from the beginning. Could you give me a tip as to why this could be?
Love your tutorials! In this one, I was wondering how to add the colon to the display. I'd need to adjust the code, of course, to light it and keep it lit throughout. But you'd have to 3d print the colon so you could wrap the LEDs around it, be it a circle or square. Like to know your take on it! Thanks again, Alister.(Not sure of the spelling of your name!?)
Yeah, definitely! My enclosure was based on a remix of this design, which already features a colon so you could probably use that one (or something very similar!): www.thingiverse.com/thing:3136688
A suggestion ... Instead of coding in the LEDs as part of the strip, you could do two LEDs separately on their own Arduino pin to change color with the rest of the digits. Or, if you didn't use the color changing aspect, you could just use two LEDs (non-neopixel) that are just connected to power, since they would be on all of the time. Just a thought!
I have designed a 6-digit 7-segment display for dynamic indication of the address and data of a laboratory microcomputer, which requires only six bytes (8051) to write to. However, the display contains 12 chips and a diode matrix with 34 diodes. Can anyone suggest a way with fewer chips for such an indication? A prerequisite is that they must not be programmable microcircuits(the project involves the creation of a microcontroller system WITHOUT the use of programmers).
Your Google Drive Frame.stl model is bad. Ultimaker Cura says "The highlighted areas indicate either missing or extraneous surfaces. Fix your model and open it again into Cura." The model from Thingverse does not have the opening for the wires and seems like your model from Google Drive is exactly what I am looking for. Do you have a Fusion 360 file for this model?
Hi! This is exactly what I was looking for. I'm designing a two-player, two digit score board with a two-digit shot clock in the middle and I love the idea of using the WS2812B strips. I was wondering if there is an easy way to scale up/down the size of the digits. Say, for example, I wanted to make the shot clock in the middle the size in your project (4 LEDs/segment) but wanted to flank it with two score counters on either side that were smaller, using only 3 LEDs/segment. Can you maybe point me in the right direction to do something like this?
Ahub Oktevs, I wanted to make a watch according to your instructions. Unfortunately, the 300 line keeps showing me the error: RTC' was not declared in this scope RTC.read(Now); I'm a beginner and I don't know how to solve this problem.
I have found this very interesting. I am hoping to build a cricket scoreboard during the winter. Would these digits be visible from a wide angle and can the digits be made a bit bigger?
This is awesome, I have been looking at how to create a set of lap counters for long distance swimming at my club. The cost of lap counters are very expensive and this could be a great way of doing it. I will need to house two digits in a waterproof case counting down in twos from 60 (or 32 for 800m). My initial thoughts was to have them with internal rechargeable battery packs and to swap out the Arduino for a ESP32 so that I can trigger counter for each lap independently. I am a bit of a noob to all of this but do you think my idea sounds achievable?
I couldn't find them either. His words in the video were "anything greater than about 6.3V & about 1000 micro farads." From my limited research I think you just need more voltage than the circuit (that's why 'at least' 6.3V) I found a variety pack with some 10V 470uf capacitors in it. They seem to work fine.
Awesome!, great tutorial and detailed explanation. I whish I could get some advice on turning this into a Dominoes scoreboard, that is how I found you here.
This tutorial is brilliant, thanks for it, finally it helps me to understand the LED strips programming. How could I contact you if I would like to do more stuff like this? Thanks a lot
Hi Leigh, you can find the download here: drive.google.com/drive/u/1/folders/1QjP0X0SCyLuz6ssbjkV6EwPs4TFJ1ZTz It was removed following a v. confusing legal issue with Patreon - because I was using 3D models that had been based on a previous CC-licensed design (even though that was perfectly allowed under the licence!), I was informed that I had to remove the project from my subscription Patreon because it was felt I was "charging" for someone else's work... even the Arduino code which is entirely my own!
@@PlayfulTechnology Wow! The crazy part is the code is really the only thing the full DIY person requires, is your own work, and, charged accordingly! You just can't win. Thank you all the same, I'll drop some cash in your Patreon.

4:30 It's good practice to add them why? What electrical effect does it 'solve'
where is the arduino code for this? ty
Awesome - love the simple solution of rgb strips with one data line and only 5v
Would this display be bright enough to see outdoors?
Hi!
Simply brilliant, I appreciate your work, thank you for all the efforts you take to make this wonderful project.
Where can I find the code for this?
Interesting project explained very clearly. Thank you. 👍
Great job, nicely explained....thanks! Very timely (no pun intended) as I am looking into escape room timers as we speak.

Can you update ?

Did you ever get them as the links are broken now too
The two links to the models have gone :(
I don't see this project on your Patreon website. Is there a way to get the sketch code, I just want some pieces of it for a different project?
How much power does it use?
Are you selling the complete materials project?

I also used 3-segment LEDs and modified the following lines:
#define NUM_LEDS_PER_DIGIT 21
#define NUM_LEDS 84
// matrix for 3 segment LEDs
const uint32_t digits[10] = {
0b000111111111111111111000, // 0
0b000111000000000000111000, // 1
0b000000111111000111111111, // 2
0b000111111000000111111111, // 3
0b000111000000111000111111, // 4
0b000111111000111111000111, // 5
0b000111111111111111000111, // 6

0b000111111111111111111111, // 8
0b000111111000111111111111, // 9
I hope this was helpful.
Can we please mention how satisfying the counter on the 7 segment display matches the video time... Anyone?
It's almost as if a second is a universal concept.. /rolleyes
Brilliant tutorial.... this is my first comment ever for any tutorial
Ahub Oktevs,

Thank you
Thank you for this tutorial, this is a brilliant idea. But is it possible to get this countdown timer on the edsim51 simulator?
How would you turn it into a clock?

Great work. I'm going to cut the strip and solder it with wires to save on wasting that single LED. It's so easy so why not?
Absolutely, you can do that instead!
super i like u r display program and definition 👍
Great work - thank you. Printing mine right now. Is there somewhere we can chat?
ignore me - found the Patreon link :-)

I am developing something similar with an ESP32 to make a goal counter, fouls, stopwatch for basketball, have you had any progress in your project?
I can seem to find 470 uf 6.3 capacitors. Can I use something else?

Dude thanks
I made my cloak whit wled + a D1 mini 👍
Nice. What software did you use to display the components.tnx
Fritzing.
@@PlayfulTechnology thanks
I dont have access to a 3d printer. Could I purchase the "pre-made" from you?
Just need the plastic parts, I can do all else
I am in the same predicament - don't have access to a 3d printer and would like to try my hand at this.
Where's the STL link?
It['s a remix of this design: www.thingiverse.com/thing:3136688
my friend asked how long its typicallly takes u to post the patreon only post
It normally goes up within an hour of the main video - it just takes me a while to gather together all the links and upload the resources!
@PlayfulTechnology Can you please post the code for this? I built the display and am now truing to get it to function.
pretty irritating that you're not providing the code.
nice !!!
