Hello
I want to Scroll "Hello Word" on LCD Screen and same Scroll on LED Display, with using one arduino controller, it is possible?
Thanks,
In your mind... (so we are all on the same page)
What is the differences between the:
LCD Screen?
LED Display?
The LCD is the 16x2?
and the
LED display is......? what exactly?
From what I understand most of the LCD screens have a backpack on them so you can use serial or I2C...etc and wont need anything else outside of the library.
If your LED display is a bunch of leds set-up like a 7-segement digit....
I would use the MAX72xx library to send the individual character/number to and have it output using the library.
However what & how your LED display is set up will be the dictating aspect..
Look at parola.h library for the MAX7219 part of the project
ok,
thanks
i will check
I try but it was showing below error.
exit status 1
Error compiling for board Arduino Nano.
Invalid library found in C:\Users\lbss4\Documents\Arduino\libraries\max7219-master: C:\Users\lbss4\Documents\Arduino\libraries\max7219-master
When you install a library you should remove the -master bit from the folder name.

Same image was attached.
no.. it wasnt.
there were NO images attached in your first post.
an LED MATRIX display is what you have
I try, but some problem is there

I try, but some problem is there
That doesn't cut it here. What problem?
A compile error?
It runs but does not do what you expect? - if so what does it do?
my aim is "Electrical Department" first in LCD display and then LED display, and as per my aim working but after 3 scrolling in LCD display it was stop on Electric and then start scrolling in LED display.
LCD= 162 LCD display
LED = 88 LED matrix (MAX7219)
Almost all completed, but one new problem is there, anybody help me.
when i connect arduino with USB all working good, but when i connect arduino with other source, at that time only One LED (8*8 LED Matrix MAX7219) working.
thanks
this is my circuit

HelloI want to Scroll "Hello Word" on LCD Screen and same Scroll on LED Display, with using one arduino controller, it is possible?
Yes, both is "possible".
Just depends on your programming skills.
While scrolling on a 8x8 LED matrix is possible pixel by pixel, on a 1602 text-LCD you just can scroll character by character by character.
So no "soft-scrolling with 1602 display. It's more slip-stick scrolling on a 1602 LCD, what you can achieve at best.
You have no decoupling capacitors in that circuit. You need a 0.1uF ceramic on each chip and a 100uF or so across the 5V supply.
Here is why :- De-coupling
ok, i will try
i will put 0.1mf capacitor with each display, and 100mf for main 5V supply line.

No those values are micro Farads not milli Farads. The 01.uF must be the ceramic type and you must put it across the power and ground of each MAX7219 chip, not the display.
