4 Digit 7 segment display using Arduino

[@ElectronicsSimplified7]

The code is updated. If you have any request on altering the code or using it in an application like a digital clock. Drop in your queries to [e-mail]

[@jakis_gosc123]

Thanks guy, my 7 segment display working correctly now.

[@pentosdso3757]

very nice but please turn the volume from the music a bit down

[@sgayle]

can you set it like a timer? like 2 minutes and connect it to a lightbulb?

[@ElectronicsSimplified7]

Yes the timer works as a perception of vision. If you want that video. Please email me at [e-mail]

[@swishwack5983]

The code seems to have LOW, HIGH values inverted? f.e. number 1 has only pinC and pinB set to LOW, while those are the only pins that should be HIGH to make number 1. After reverting LOW to HIGH and vice versa it started to show me the numbers correctly. What am i missing? :D BTW thank you for the video and code - the best tutorial on the topic i found :)

[@ElectronicsSimplified7]

You need to identify the type of segmented display you are using. Anode or cathode. Everything changes based on that 😄

[@ElectronicsSimplified7]

In my video. I guess it's a cathode display (so all the values are inverted)

[@happyy6826]

Could i use this same wiring and just add in an mirco switch into the breadboard so when pressed it would light up as an scoreboard?

[@ElectronicsSimplified7]

This current circuit can't be used as a scoreboard

[@happyy6826]

@@ElectronicsSimplified7 Oh i see, do you happen to have a video for using this display as a scoreboard? Appreciate the reply.

[@shortsvideolover3315]

Which is the ground pin in the display??

[@mikey_spideyFT]

Breadboard

[@richardc4215]

Why is pinDP (segment 3) never used besides setting it as an output?

[@ct8463]

thank you sir for this amazing tutorial like and sunscribe

[@writingskills.1888]

Sir it is giving a compilation or library error.

[@ElectronicsSimplified7]

Download the library from the link in the description. The link will take you to the post. But the post has a sevseg.h library on top ... Please download it ... And put it in your Arduino/libraries/ directory

[@artelislt]

Tysm for the code

[@sebstudios-l1p]

How many ohms do those resisters have?

[@ElectronicsSimplified7]

Standard 1kohms

[@laurenwithhart1076]

Can you make a functioning alarm clock?

[@ElectronicsSimplified7]

Yes surely.

[@villepyykko6643]

Hi. I would like to use this on my chain throwing outdoor game score counter. There is like 4-6 different size holes where you try to throw the chain through. It would perhaps need some ir censors or something else what the chain would activate when it goes through the hole and give you that amount of score in the display what you have decided to give from each holes. Would you help me build that? If yes we can continue with mail..kind regards. -Ville

[@sharmisthakundu5877]

What are the values of your resistors you used?

[@ElectronicsSimplified7]

All 1k

[@ColvocBlue_12]

You can use 220 to 330 ohms resistor for each segment pin

[@alexanderalt265]

Can it do negative numbers?

[@marms1232]

yup, if the variable inputed to the display is negative it will display a - symbol

[@yalcinketenci2107]

Great tutorial thank you. I have one question how to highlight the dots as well?

[@thisoldjeepcj5]

Well explained tutorial. Thanks

Glad it was helpful!

how about 3 digits with keypad?

Hi, can you help me i want to make the 4digits of 14 segmments of the microwave mef 33 connecting in the bluetooth if i touch the letter a for example appear in the 14 segmment display

[@kevinmurphy3539]

Mine don't look anything like numbers. I rewired it again to be sure. What am I doing wrong

The code is a download file for PC and if that doesn't work. Now the code is on a webpage too, so you can copy it and use it. Cheers!!

Help i want to power up the 4 digits of 14 segmment display of the electrolux microwave mef 33 like the clock but with 58 on/off switchs like a flashlight 56 on/off switchs for a 4 digits of 14 segmment display and 2 on/off switchs for 2 dots , plis?

Sorry, but your voice is barely audible, the accent makes it harder to understand what you're saying, and - to top it off - the F(#)G music drowns it all! Please, re-upload it WITHOUT the nasty background music, will ya?

@@Bandicoot803 you’re mighty hostile to the person giving you free educational content. There’s no need to be passive aggressive and diminish his English abilities. I understand him just fine.

[@Bandicoot803]

@@me-ye6ld Free educational content is one thing. But providing it to the world in a decent way with thoughts about the receipients feels comfortable about it is a different story. These two factors have to harmonize in unison, which - obviously - in this video is not the case. That why I stated my opinion with common consent, something you certainly have to start gathering in order to make up your life. If you misjudge other people by doubting their skills, then I'm sorry that I can't help you regarding this. It's completely up to you. I happen to live in a free and democratic country where common opinion and press freedom are at upmost value, and I'm not allowing ANYONE to whittle these rights away from me.
