Learn How 4 Digit 7 Segment Displays Work
Переглядів 105,519
4 роки томуLooking 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.

Best video explaining how 7 segment displays work. Great job!
@IgorPomaranskiy Рік тому
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✌️

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 👍😃😃🙏

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

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

@aminekhaldi2004 3 роки тому
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.

@milanganguly8751 Рік тому
For some reason mine doesn't work. I turn on pins A and D1, but nothing happens... Could I have some help?
@TRRailfan Рік тому
which pin is for the ground?
@quinn2090 4 місяці тому
All digits are connected to negative if you want them on
@quinn2090 4 місяці тому
Every other can be on positive for on
@ColvocBlue_12 2 місяці тому
It depends on the type of display you have, you can have a common anode display or a common cathode display.@@quinn2090

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

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

D,E not work inductio cook But led display no damege(seprate check) Any Data problem?
@kalyangautam7345 3 роки тому
Which pin is for D2 & D3 decimal point ?
@dave4lexking 3 роки тому
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.

The dp pin (you can find it in the pin diagram shown at 0:40 )
@henriqueers 3 роки тому
Where's the pin for GND?
@puneethkumar703 3 роки тому
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 2 роки тому
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 Рік тому
@@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?

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