Learn How 4 Digit 7 Segment Displays Work

[@abdulazizali4395]

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

[@danirodriguez5665]

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

[@IgorPomaranskiy]

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!

[@yungsteezy4500]

best datasheet on the internet

[@aryamansetia6122]

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✌️

[@puneethkumar703]

hello Aryaman wokwi.com/arduino/libraries/SevSeg is the link for the free Arduino simulation page for seven-segment display. I hope it is interesting to you. Please give a like if you think the suggestion was good 👍😃😃🙏

[@cristinocanga]

This so brilliant Thanks for the explanation

[@babyayalew8059]

thank you you gave a rest for my Brain

[@hsjdiekkei]

Same bro

[@TRRailfan]

which pin is for the ground?

[@quinn2090]

All digits are connected to negative if you want them on

[@quinn2090]

Every other can be on positive for on

[@ColvocBlue_12]

It depends on the type of display you have, you can have a common anode display or a common cathode display.​@@quinn2090

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

[@fekaduabayneh1673]

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

[@aminekhaldi2004]

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.

[@user-kito-bunbunkitofriend]

What about DP?

[@D-ingus]

how is it grounded though?

[@andersdoesthings9309]

For 5641as it usually has 4 common anodes or cathodes, 6, 9, 8, 12.

[@D-ingus]

@@andersdoesthings9309 ah thanks. I appreciate the hasty reply

[@andersdoesthings9309]

@D-ingus dang, just stumbled upon thr video and saw this comment, thought I'd answer even though how late. Just to be helpful to maybe you and other people who read this comment.

[@D-ingus]

@@andersdoesthings9309 and i appreciate it

[@polycoder]

Quite helpful thank you very much

[@ehomen9310]

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

[@HikeYegiyan]

Thanks, this video helped a lot!

[@henriqueers]

Where's the pin for GND?

[@puneethkumar703]

The LEDs only need voltage difference between ANode and cathode to turn on. The Arduino pin connected to Anode will be driven high and the Arduino pin connected to the cathode will be driven low. By this, it is achieved, wokwi.com/arduino/libraries/SevSeg This link 👍👉 is the free Arduino simulation page for 4 digit seven segment display. for more such free simulations, visit: wokwi.com

[@lambdasun4520]

you tie the VDC - to the digit choice pins that are shown green in the video. Don't forget to put a resistor at the positive side or the LED's will burn.

[@Mr_Ioannis]

​@@lambdasun4520 So if u want to power (for example) the first digit, all the rest of the digits act as ground? Am i correct on this?

[@thevastenigma2464]

Great video!

[@percent2520]

How do you light up :

[@High-TechSolutions]

how about the colon?

[@milanganguly8751]

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

[@sudharakafernando4391]

Thank you!!!

[@bernardofernandez5682]

Thank you

[@Justbeingcris]

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

[@puneethkumar703]

hi there wokwi.com/arduino/libraries/SevSeg you can find the code as well as online Arduino simulation here: 😃👉 also more free Arduino simulations are here: wokwi.com

[@pabloramis8890]

And the longtek duplex display to lm8560????

[@andydoe5549]

I recommend all students who are doing ENG1013 to watch this

[@kausn2759]

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

[@kalyangautam7345]

Which pin is for D2 & D3 decimal point ?

[@dave4lexking]

4 digit 7 segment displays with a colon usually have additional pins. You'll have 7 pins for segments A-G and 4 pins for D1-D4 and a pin for DP as normal (12 in total) but you'll often find 2 more pins, which are for the colon (:) between digits 2 and 3.

[@michealmyers4515]

You can always google the pinout ,no need to remember

[@srmobi_fix_ittechyt2672]

A,B,C,D,E,F,G-D1

[@probhatisaha6056]

The dp pin (you can find it in the pin diagram shown at 0:40 )

[@jul371-y5p]

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