Do you have a question ?
How can i do that? Put bigger LEDS on this TM1637 board?
What do you mean as LEDS? I don't see any at the picture.
It is a seven-segment indicator and I don't know a way to replace LEDs in it. You only can replace an indicator as a whole.
I note that you edited your post after I asked my question
Each segment on the board is probably a single LED that you could remove and make connections to a larger one situated off the board. However, if the segments are going to be larger you will need either multiple LEDs per segment of a larger light pipe to spread the light over a larger area
You would be better off by building a whole new display or buying a larger one
@UKHeliBob
I think that OP needs larger symbols, not larger LEDs.
Hence what I said
You are not telling us very much. We only know what you tell us. So far this I very little.
So what Arduino do you have?
What is the exact board do you have? A link to where you bought it would help.
By bigger do you mean physically bigger or more digits?
I mean bigger LEDS like this
I want to change the LEDS to bigger LEDS
So, this board TM1637 has 12 pins like so
But i am using 5v LEDS
How to replace? - desolder the existing lEDs and put a new one.
You need to know the nature of these new LEDs.
Are they the same voltage?
Do they take the same or more current?
You know that you are permitted to answer more than one of the questions asked? Your track record is not impressive at the moment.
The same voltage! i think so. Sorry, do you recommend another forum to discuss this?
No, because this is the right one. If you feel I am being negative it is only frustration at your lack of cooperation.
So I repeat:-
Unsolder the existing display. Use a solder sucker and de soldering wick.
Then use wires to connect the board to your new LEDs.
Who cares, leds operate on current, not voltage...
You need special chips to drive large 7-segment displays, because they require a higher voltage. Sparkfun has large digit drivers (click).
Leo..
Or build your own display with addressable led strips. You can make it big as your wall, and it's still easier than playing with your 7seg display.
Can you put a 3-4" magnifying glass over top of it? Might be an easy, inexpensive solution.
If it's in your budget, maybe just make life easy and buy the solution?
