Make your own Arduino LED Matrix display 80x8px (DIY) Bluetooth Controlled (+Android app) 

This is really good and useful project...

Excellent project 👍

Congratulations, great project. I'm a beginner and I bought an Arduino nano module. would it be possible to have the complete sketc of this project? Thanks in advance. Antonio.

Do you work with FC16 modules? Or, what should be changed in the code? Thanks

This is my probleme: exit status 1 'class DateTime' has no member named 'dayOfTheWeek'; did you mean 'dayOfWeek'?

Hello, could you help me? The library of dht..I have error: "dht.h"...did you use old library? I find : "DHT.h"..thank you

sir, how to display two different text SIMULTANEOUSLY, in two DIFFERENT 8by32 max 7219, using SINGLE ARDUINO BOARD. please. in 1st 7219 i want to display name of organization. and in 2nd board i want to display date and time.

Hello I built the PCB I have all mounted the problem know that all the LEDs light up I have the arduino ver 1.8.13 IDE I do not understand why it does not work is there an SPI problem I connect CLK in 13 CS in 10 and DIN in 11 can you help me thank you

Hi,in PCBWay I can't find where to upload the gerber file, could you help me?Best regards

Great work... Can you use an image to be displayed on the matrix display rather than text? Thank you in advance

My display is scrolling vertically. What is the solution?

Can it be operated without temprature sensor and bluetooth device.? Please reply

Nice project sir 👍

Unfortunately, my display is not empty. Can I program in Arduino and then insert it into the board.

My dot matrix can't connect, I use 4 in 1 matrix ... please help

Hello sir this project is good. Sir plese send the Circuit Diagram

Another great project!!

Hello from Germany I have build this, very nice, THx for that!! I have make it longer 4x4in1 Dot Matrix and in German, All Super! My Question: I need the message text longer, is that possible? and what must i correcting Greets Volker

Excellent project... Plz give the pcb gerber file of main controlling board....all of them are well

how make this project with arduino nano or uno

pls share skematik led matrix clock 7219

One little doubt. What's purpose you used Ldr in this circuit... Please tell..

Quite handy, and useful...✔

The code has been uploaded, the schematic is correct, but the max7219 display screen doesn't want to show the clock, is there any code that needs to be fixed ... thanks

hi! how do you manage to get rid of all the jumper wires at 17:49 ?

I have this arduino R3 board okay? Then I have a block of 8 led matrix 7219 I have to add another two. How to make connections? Thanks. Very nice and interesting project so much that I subscribed to your channel. I launched the program and it gives me: dht.h Non such file or directory. How to solve it. I have 72 years and I apologize for these trivial questions.

Πολυ ωραίο..! υπάρχει περιπτωση να το πουλήσεις?!

Dimmer Arduino Ψάχνω ένα κύκλωμα, ας το πούμε Dimmer, με Arduino, γιά να ελέγξω την ισχύ μιάς βαττικής αντίστασης (220v 1600w περίπου). Ήθελα όμως η ρύθμιση να μη γίνεται με ποτενσιόμετρο, αλλά με ένα push button πατώντας το 4 φορές. Δηλαδή, ένα πάτημα 400w, δεύτερο πάτημα 800w, τρίτο πάτημα 1200w και τέταρτο πάτημα 1600w. Ένα δεύτερο push button να κάνει την αντίστροφη δουλειά. κάθε πάτημά του να ρίχνει την ισχύ από 1600w σε 1200w, 800w & 400w. Με αυτό το κύκλωμα θα ελέγχω την ισχύ της αντίστασης, μιας σιδερώστρας, γιά να έχω τις επιθυμητές θερμοκρασίες γιά τα διάφορα είδη υφασμάτων. Σας ευχαριστώ εκ των προτέρων καθώς και όποιον άλλο φίλο μπορέσει να με εξυπηρετήσε Το mail μου pane8486@yahoo.com
