Arduino Tutorial | Displaying Multiple Numbers on the 3 Digit 7 Segment Display [multiplexing]

Hello Engineers! In this video, I show you how to multiplex using the KYX 2381BS 3 digit 7 segment display tutorial. In other words, I go over how to display different numbers simultaneously by manipulating the delay between each number.

Hi and welcome to my channel! My name is Aary Kieu and I have a B.S in Electrical Engineering. I enjoy working with robotics and will be showcasing some of my projects here. I will also be posting engineering-related tutorials (ones I wished were available when I was starting out in Robotics).

❔ Questions/Suggestions
Feel free to let me know in the comments below. I will respond as soon as I can. Cheers!

Thanks for this. So the Arduino is directly supplying supplying the current for multiple LED's via pins 8, 9 and 12? That seems like it could be quite a bit.

What do the turnON and turnOFF functions look like?

I have 3 digit 7 segments with 11 pins. And, don't know what those pins are. And also, 1 digit 7seg with 8 pins. Is that worth for arduino programming?

I was trying to use your video to learn something and it seems like I am unable to do so. Your examples are not working, I found other ones that are working so connections are ok. Your methods are not clear, tabs, code in parts...
Can't you make a simple code that will work? Can you provide information such as Data, Latch, Clock pins, and then digits? Then your code would be useful not scattered all over the place.

When I built something similar to this myself my digits are just flashing across the 7 segment display and are unreadable, any tips?

Can you use it with a 74HC595 shiftregistor instead?

WOW .... Thank you
Hello pls kindly help me with the code .... i am not getting
please

Hi, I'm using a common cathode display (instead of common anode as you are using), and I've run into a bit of trouble turning each digit off. If I wire the cathode of each digit to an Arduino output, setting the output LOW can turn on each digit, but I am afraid setting the output HIGH to turn the digit off will produce too much reverse bias current and blow out the LED. Any suggestions to fix this?

I was searching online to see if a efficient method exist to do this but their really isn't it appears. Just glad I came to the same solution

I followed the link but can't find the code

How can we use it for 3 segment count down timer for 999 minutes

Can Arduino be directly connected to the display?
