How to use the TM1637 Digit Display with an Arduino (Quick Tutorial)

[@RyanChan]

Here is a function you can use to display integers on the TM1637: void displayNumber(int num){ tm.display(3, num % 10); tm.display(2, num / 10 % 10); tm.display(1, num / 100 % 10); tm.display(0, num / 1000 % 10); }

I love these TM1637 4 digit displays. I ordered some from China which come in various colors instead of the usual red.

[@3xAudio]

Great Vid. I love Arduino projects and the inspiration you get from other people.

[@CrazyCoupleDIY]

Very well explained, straight to the point without any knob-jhobs Thanks for the tutorial

[@mikeb1617]

Thank you for the tutorial, very easy and fun. l enjoyed this for the first time for me.

[@Eurus721]

Just received that display and this is very helpful. Thanks

[@nighttime9539]

Dude big thanks! I was messing around for a while and nothing was working because I was trying to use DIO and DCLK pins on my board (BluePill). Turned out I just had to use any other two GPIOs.

[@arif41man1]

Thanks for the vid, Can you display letters like U or L

[@Drxxx]

Great video!!!

[@NileshPandey13]

Very simply explained...

Hi, how can i change position and charakter value to temperature from else equal?

[@MrAlinkarl]

nice video! can you help me? when there is an input like sensor then give a time (ex. 30 min), and it display in tm1637 and countdown when the time is zero it will buzz. thanks

[@skmplanet9591]

I think you can simplify anything, Thanks a lot

How to display 3 temperature numbers on seven segment?

[@coroomchannel414]

How to display numbers with commas? For example 27.30.

[@rasmuswestergren6221]

Is it possible to use the tm.display function to generate other symbols, like the rest of the alphabet or a = ?

[@Eurus721]

Pretty sure not possible with that display.

[@SiddharthSingh-sk2md]

Can we use tm1628 and TM1668 ic

[@callumcrook7284]

how can you get 2 7 segment displays to work at once doing different things?

[@RyanChan]

You can get different displays to do different things by connecting their CLK and DIO pins to different pins on the Arduino, so for example you can connect one display's CLK and DIO to pins 2 and 3 on the Arduino, and another display's CLK and DIO to pins 4 and 5. Hope that helps!

Merci pour la video les kheys

[@loicplestan8518]

J'avvoue

@loicplestna moi aussi

[@ennohellmann8222]

Very nice video, is there a function to turn the 4 segments off?

[@avcimustafa7052]

thanks to you.

[@Eurus721]

I wonder if they can be daisy chained.

How to clear display ....can you please give me syntax

[@redenmoradz803]

How to clear the display

[@redenmoradz803]

Shoul I just use this? tm.clear();

[@EyEJ0E]

@@redenmoradz803 i have tried it doesn't work.

[@rostigerspieler]

I have used this :D void loop() { tm.display(0,18); tm.display(1,18); tm.point(0); tm.display(2,18); tm.display(3,18); } That deactivates the numbers. Not the best way, but better then nothing :P

Hi, i just loved your project and Channel #sparkbuzzer

[@jayc1983]

Hi Ryan, great tutorial video even for us noobs. i need help on probably very easy setup and coding. can i contact you somehow? email? would really help me out.

[@RyanChan]

Thanks! Also, you can post your question in the comments, I'd be happy to help!

[@jayc1983]

Ryan Chan hi. I think over messenger would be easyer but what i want to do is: Control a tm1637 display with a potentiometer. Showing numbers from 0:00 to 9:99. Components arduino nano, potentiometer with on off function, cr2032 coin as power source, step up module and of course the display itself

[@RyanChan]

@@jayc1983 That's a good question. I've made this function to make it easier to do that: void displayNumber(int num){ tm.display(3, num % 10); tm.display(2, num / 10 % 10); tm.display(1, num / 100 % 10); tm.display(0, num / 1000 % 10); } To make the TM1637 display a number, paste that function into your code and pass in the integer you want to display into the function. So for your project, I suggest mapping the value of the potentiometer and then passing that value into the displayNumber function like so: pastebin.com/Xi5T5H7B Thanks for bringing this up, I will pin that function in a comment so others can use it as well
