74HC595 Seven Segment 2 Digits LED Display with decimal points for Arduino

When using shift registers like 74HC595 or CD4017B, how is it that you can define which pins you plan to use on the IC? That’s little confusing for me.. I don’t see how you can choose which or an exact output pin you’d want to use??

Hi Ahmad, thank you for another cool arduino video ;) Could you do one about extending the arduino nano to control several stepper motors , a display of values regarding motor behavior or position, and potentiometers to set motor speeds or to get them to move when you turn a potentiometer ? I know that's quite a project and i dont mind if you dont do it as i descibed it but now you see what kind of needs makes me wonder what is the best way to extend the nano's pins number. Anyway, i really appreciate your videos, take your time with editing the videos man ;) have a nice day !

i like 7segs, pls next project use bigger ones :)

why show the decimal point on the #2? it isn't needed to look like a #2

THANK YOU AHMED

hi there, im running a LED 5604 Display, may application is only start top timer with decimal betweem segment 2 and 3, my problem is to start the count down to 1 to 99.99 secconds, also I want to add a button for start and button for stop. Plus beep sound during the start button is pressed.
whem im using your sample the coundown starts at 100

It's working :DDDD

THANK YOU SO MUCH. IVE BUILD A FLUX CAPACITOR FROM THE MOVIE BACK TO THE FUTURE. IVE SPEND DAYS AND NIGHTS LOOKING/RESEARCHING FOR CODE AND SETUP FOR 2 DIGITS COUNTER TO DISPLAY 0-88MPH. THIS IS PERFECT.
" IT WORKS....FINALLY I BUILD SOMETHING THAT WORKS".....WITHOUT YOUR HELP I PROBABLY BE STILL RESEARCHING FOR CODE OR WRITING ONE !!! Thank You

Hey how can i make this work with a DHT11 ? I combined my DHT 11 code with yours and he displayed me the temperature and humidity value but also displayed some random characters . Any ideas?

Is exactly what I've been looking for! But need trim potentiometers the 2 7 segments should roll from 00 to 88. When it shows 88 it should output 12V current with a ticking relay for each digit

Another superb video, Would you please cover s topic about removing zeros in seven segment? and using Large seven segments. Thanks again for this wonderful tutorial :)

Where can I buy this display?

Everything worked great! How would you make the tens digit to be blank when I only display single digits - I dont want to see a zero in the tens digits when showing 0 thru 9 - Thanks

hi, i find error on " ShiftRegister74HC595 sr (DIGITS, SDI, SCLK, LOAD);"
" invalid use of template-name 'ShiftRegister74HC595' without an argument list"
how to fix it??
please help

Hi. Apologies if this is super obvious but where can I purchase one of these two digit units?

Awesome video, but can you help me with writing 10 digits insted 2 digits

How do these connect to the Atiny85 chip?

what is "invalid use of template-name 'ShiftRegister74HC595' without an argument list " mean?
I have download the zip. .

Is there any code for the 3 digit 74hc595d?

hi, can you help with the (AVR) assembly to control the SCLK, SDO, and LOAD pins? how to determine which digit to write to with the TZT 7 segment display (based on 74HC595) with only the three pins?
