Learn How 4 Digit 7 Segment Displays Work

Looking to build an #Arduino based project with a 4-digit 7-segment display? Trying to make sense of all the pins on your display to get them to work? This video will walk you through how a 4-digit 7-segment works so you can correctly build your circuit and write code to run them.

This was so useful i watched a lot of tutorials and i understood it in less than 5 minutes!

Best video explaining how 7 segment displays work. Great job!

I spent the whole Sunday evening trying to figure out, how do force my code to display all 4 digits. :D Just to find this video, explaining that it's not technically possible without some 'animation' work.

So, it looks like I'll have to deal with timers and interruptions.

But this is a topic for another Sunday evening, I guess. :)

Thank you!

I could not find a better video. As it explains the important points and moreover saves time as it is short. Thus more time on designing my own project rather watching vedios✌️

Realy good video but i didn't get where to put the groud/power there is only 12 pins and no one of them is a gound

hi amazing video just wanted to say that either the order of digits is reversed (one on the right is D1 and on the left is D4) or the pins that are actually switched hope u can verify that later.

I coudnt even light up my 7 segment until this video 😂

thank you you gave a rest for my Brain

For some reason mine doesn't work. I turn on pins A and D1, but nothing happens... Could I have some help?

0:35 this 7 segment display is the transmitter (88:.88)

And the longtek duplex display to lm8560????

hey thank you this helped a lot i was wondering if you could do a video on how to code for a 4 digit segment display

D, E not work inductio cook
But led display no damege(seprate check)
Any Data problem?

[kalyangautam]

Which pin is for D2 & D3 decimal point ?

[andydoe]

I recommend all students who are doing ENG1013 to watch this

Well works for a brand new display
Bot for a scavenged 30pin one
