4 Digit 7 segment display using Arduino

#display #digit #segment

Code:

Library:

(Please check the post for all the details. you will need to add the library sevseg before running the code)
The 4 digit 7 segment display in an intermediate level project for beginners. This project is mainly focused on how to connect the seven segment display with the Arduino and mBlock. Once you have learnt the connection and the logic of working. Nobody can stop you from reprogramming the segment display.

To get started we will need an Arduino (Uno or whichever one you have that would not make a difference). But ideally as the number of pins increase on our Arduino boards the capability is higher and better projects can be built.

Thanks guy, my 7 segment display working correctly now.

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?

[shortsvideolover]

Which is the ground pin in the display??

[sgayle]

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

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

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

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 :)

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

[ct]

thank you sir for this amazing tutorial like and sunscribe

[writingskills.]

Sir it is giving a compilation or library error.

[sebstudios-lp]

How many ohms do those resisters have?

[sharmisthakundu]

What are the values of your resistors you used?

[GuilhermedaSilvaCaetano]

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?

Jesus love u🙏🙏

[laurenwithhart]

Can you make a functioning alarm clock?

[yalcinketenci]

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

[kevinmurphy]

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

it says this:

what do i do

[adviktripathy]

Compilation error: conflicting declaration 'int D1'

[girijagolla]

How can I execute without external library
