Tutorial on how to make a Single digit 7 segment Count Up
HTML-код
- Опубликовано: 20 июн 2012
- In this video tutorial, we show you how to connect a single digit 7 segment display to a breadboard, connect the Vcc (power) and gnd (ground) jumper wires. As a prerequisite, you should read our brief tutorial to learn what a single digit 7 segment display is and how they work (www.jayconsyst.... All components can be located at www.Jayconsystems.com website, and are also included in the Arduino Starter Kits (beginner, and intermediate).
Part 1:

The code can be found on Part 2: www.jayconsyst...
My teacher said that this is very helpful tutorial

Tank very much Master..good.
It works, first go, amazing!
Thanks very much.
Good to hear! You're welcome😊
Your code on the website is missing. Please fix it!!
New to all this , but the LED was to bright , might burn out , so added a 1k ohm resistor to the ground lead and this worked ok. Not sure if that was the best way to do it ! . Anyone else do it this way ?.
Shouldn't you use resistors? Blowing 5V through that display will ruin it.
Thanks for the video, good work.
Hey below!! I think paying closer attention instead of lashing out might be helpful because the code is there! Try at least to make a little an effort. sheeeeez
Thanks for your video!
what type of 7 segments do you use?? anode or cathode?
I used arduino mega, I follow the pin configuration, 7segments pins (3 and 8) are connected to the gnd. I used the ur code and the code by brandon day but it doesn't seem to work on me
Wooow. That's great...keep it Bro
Thank you!
Great video and site. Was able to make this using a nano without any issues.
I have a 3 digit common cathode display i am trying to figure out how to wire properly. Could you explain a little more about wiring?
this tutorial is the most frustrating thing this side of the Mississippi
pin 1 = bottom left
pin 2 = bottom
pin 4 = bottom right
pin 5 = point
pin 6 = top right
pin 7 = top
pin 9 = top left
pin 10 = middle
if you put a current to the respective pins and have grounds connected, respective segments light up.
the config works with the first pin being bottom left, where the dot is facing you.
THANK YOU for sharing these . Very simple explanation and easy to folow . Do You have more video with Arduino ?. I am at the first steps with it and You way to explain was great and easy for me to understand . THANKS .
Be well and stay Safe .
Great video thanks
is the connections for a common anode display? im new to arduino
and im just a kid
Hi ...it did not work for me. I have arduino ATMEGA 8A which is an older version. can u tell me where lies the problem , everything is done as per your instructions in the video.
int bottomLeft = 2;
int bottomMiddle = 3;
int bottomRight = 4;
int dot = 5;
int topRight = 6;
int topMiddle = 7;
int topLeft = 8;
int center = 9;
void on(int num) {
digitalWrite(bottomLeft, (num == 2 || num == 6 || num == 8 || num == 0));
digitalWrite(bottomMiddle, (num == 2 || num == 3 || num == 5 || num == 6 || num == 8 || num == 0));
digitalWrite(bottomRight, (num == 1 || num == 3 || num == 4 || num == 5 || num == 6 || num == 7 || num == 8 || num == 9 || num == 0));
digitalWrite(center, (num == 2 || num == 3 || num == 4 || num == 5 || num == 6 || num == 8 || num == 9));
digitalWrite(topLeft, (num == 4 || num == 5 || num == 6 || num == 8 || num == 9 || num == 0));
digitalWrite(topMiddle, (num == 2 || num == 3 || num == 5 || num == 6 || num == 7 || num == 8 || num == 9 || num == 0));
digitalWrite(topRight, (num == 1 || num == 2 || num == 3 || num == 4 || num == 7 || num == 8 || num == 9 || num == 0));
}
void setup() { // Our setup routine
for(int i = 2; i < 10; i++){
pinMode(i, OUTPUT);
}
}
void loop() { // Loops forever
for (int i = 0; i < 10; i++) {
on(i);
delay(1000);
}
}
your a mad lad. Thankyou
7D instead 7C on num6. And thanks for tutorial.
Thank u man you helped me a lot :)
Thanks Bro
thank you sir.
Would be nice for a higher resolution video, great work tho, thanks
9 years :D
cool, but the numbers are too bright, is it possible to give less power to the display?
it might be too late but you could and should use resistors if you dont want to damage the display
ser do you have a .js code for this. i really need it for our exam
dear sir
could you please help me for fix voice in arduino
Why is it so blurry
there's no code @ the link!
Optimized Code. Took 45 minutes to from "How do I do this, let's watch the tutorial" to testing this optimized version out and posting it here.
int bottomLeft = 2;
int bottomMiddle = 3;
int bottomRight = 4;
int dot = 5;
int topRight = 6;
int topMiddle = 7;
int topLeft = 8;
int center = 9;
void on(int num) {
digitalWrite(bottomLeft, (num == 2 || num == 6 || num == 8 || num == 0));
digitalWrite(bottomMiddle, (num == 2 || num == 3 || num == 5 || num == 6 || num == 8 || num == 0));
digitalWrite(bottomRight, (num == 1 || num == 3 || num == 4 || num == 5 || num == 6 || num == 7 || num == 8 || num == 9 || num == 0));
digitalWrite(center, (num == 2 || num == 3 || num == 4 || num == 5 || num == 6 || num == 8 || num == 9));
digitalWrite(topLeft, (num == 4 || num == 5 || num == 6 || num == 8 || num == 9 || num == 0));
digitalWrite(topMiddle, (num == 2 || num == 3 || num == 5 || num == 6 || num == 7 || num == 8 || num == 9 || num == 0));
digitalWrite(topRight, (num == 1 || num == 2 || num == 3 || num == 4 || num == 7 || num == 8 || num == 9 || num == 0));
}
void setup() { // Our setup routine
for(int i = 2; i < 10; i++){
pinMode(i, OUTPUT);
}
}
void loop() { // Loops forever
for (int i = 0; i < 10; i++) {
on(i);
delay(1000);
}
}
Used this without resistors and now that segment dosn't work
220 was very bright, 2.2k worked well though
you don$t need soending in a microcontroller for that. A very inexpensive IC can do the job
4 digits single of 7 segment? how do?
i got just numbers 1,2,3 and 7. help please
You have wrong sticks or the wrong 7 seggent.
There is no code for the arduino. plesae fix it.

@@abdelnacer7721 thank you, i get a 404 error when i go the site with the code
WHERE THE HELL IS THE CODE
404 error....
2012?
no code :(
404 error.. :(
Your code is too long for a good programmer, try to make it short. :)
Romuald KOUAMI TCHAMBA i saw this comment and agreed. what do you think of this?

do you have any codes for that? i need this as soon as possible
All this "tutorial" does is show somehow how to copy someone else's work. It doesn't show you anything but copy/paste. What a waste of time!
