Arduino and the 4 digit 7 segment led display – Anything Arduino Ep 21
In this arduino tutorial I explain how to work with the 4 digit 7 segment led display, and the difference between the four digit display and the one digit display, and how you can connect four one digit display to work just as the four digit one. I then show how to multiplex the common pins to be able to write different numbers to each digit. To see how the numbers are made watch Anything Arduino Episode 7 where I make the arduino sketch that we use and alter in this video.

thanks for the video!!!
Why can I only output 2 segments and extremely dim other ones
for some reason when I do this If for example I want it displayed on the second digit I need to turn the first, third, and fourth all on high to do that. does anyone know why this is?
Very nice work. Easy to understand. Thank you
Oh Sweden, that's where the accent comes from … sorry, we don't get out much … especially with the virus 🙂
Dumb! I'm drinking vodka so I'll be pretty happy pretty soon 🙂
Thank you very much! What I needed!
CAN YOU HELP? I HAVE A 4 SEGMENT CLOCK MODULE THAT HAS 3O WIRES ON THE BOTTOM AND AM HAVING PROBLEM GETTING PINOUT OFIT.
no sketch files
Please put a 550 ohms resistor at each led input or you will kill em all
Why is it that I have to flip all the high and low around to match what is being shown in tutorial? I have a Elegoo Mega2560 board.
You wrote a link on your description that redirects us to that Duinos page that has the sketch files (as expected). But when i clicked the link, and entered that duinos website i saw no sketch file. please let me know where to find it
Also works with Atmel 2560 project
Great video, very helpful. 🙂
nice tutorial……. respect from INDIA
Thanks for this!
In some cases for the D1,2,3 or 4 you should use LOW so it can run 😉
hi there can you help me about my 4 digit segment LED 5604 module. all I want is counter upto 0 t0 99.99
Could you please explain 3 digit 7 segment LED.
thank you man eaxctacly what i was looking for
pls do not use integers in places where you can easily use defines. this triggered me so hard
Good
Do you need to use dupont wires or can you the normal wires?
Thanks so much sir… Such a nice tutorial… Respect from Bangladesh
Please can some help send data to uno via wifi with android app
Please can you make a video how to send text from android app using wifi module with 7 segment display
How would i go about turning this into a digital clock? Yours is the closest i have come to understanding how to do this.
Thank you very much, a great explanation. you explain well.
Thanks. I am trying to make a video game device like a nintendo game and watch using arduino. I found this very helpful.
Very well explained and simple to understand. This is my first working project with arduino. I am also going to repurpose it into a small digital clock. Thank you for the great tutorial.
no sketch…

No resistors?
You'r helpful thanks
The code on your site is corrupt but I was able to figure out what is going on based on your training! You do man!
Who else doin this for rick and morty
can i read the output signal of arduino going at led display to another arduino ?????
Thx bruh
great vid! . .thanks – but why do you not use resistors before the LED?!
Really thank you
Where are your current-limiting resistors? Why are you connecting this display directly to Arduino outputs without resistors?
I need
Kodd send me😊😔
Norsk
anywone wachting this in 2019
Felt like I was being taught by Floki from Vikings! 😀
My display is not doing anything. I've dissemble it several times. Code is compiling fine. There is no power going to the display at all.
Hi, im trying to finish my project but im having trouble in my codes. How can i make the zero remain in the 1st tube after looping and so o , until it goes back to the first one and loop again? Thank you
am i the only one who knows that the website is broken
the website wont let me get/find the sketch
