Hi ahve tried again this project using libraries from your package and all leds are turned on. I'm using 8x32 led matrix. It seems bluetooth is working correctly but once all leds are on I can't see any message.
Hi, first you need to go to goo.gl/RUpzQf. There, you will find 3 folders. The accurate code is in the folder Arduino_BT_to_LED_Display. However the other 2 folders are also needed to compile the Arduino_BT_to_LED_Display.ino code. They are actually the library files and need to be install into your PC to compile the accurate code. HC-05 works just similarly as the HC-06. Thanks!
Really it is very amazing project. when it is active showing here "welcome". After sending any kind of text via bluetooth, showing here different text(Like if sending "Bluetooth" it's showing " ÿô ". Anticipating your suggestion.
Thk u I tried today from moring 2 am .I failed nearly more than 60 times .And I passed in 61th attempt by modifying ur old code with MD_MAX72xx HARDWARE::FC16_HW MD_MAX72xx(HARDWARE,cs,maxdevice). And tantadan it worked.Actually I made my own matrix .Hence i was crying lot.And finally u came like god to me to show the path.
Greetings Nudge Me! I did all the correct procedure and connections but did not find the bluetooth device; I have the HC-05 and the HC-06 but can not find any - what can it be? The code is correct because it showed "Mula" in the Serial Monitor; Thank you
Daniel Fernandes Hi, i guess you might have missed the pairing step between your phone and the HC-06. Watch this video ruclips.net/video/MBs023AoHQk/видео.html and go to minute 2.17 to 2.33 to see the required step. This step is required one time only; once you have paired the particular BT module, it will permanently appear in the app each time you launch it until you delete it manually through the phone's BT setting menu. In this video I have skipped the step and that's maybe why i think you have missed it.
Thank you for answering my friend! I made the pairing! Connected succesfully But it does not send (SEND) the message; always stay at the Welcome! If you can give me any tips, I'd appreciate it; if not I'll try here; thank you
Yes! I'm suspecting that my module is burned or something; But the interesting thing is that the bluetooth is recognized on the cell phone and the module light flashes intermittently slower. Do you have any way to test the module? Once again, thank you.
There are types of Bluetooth modules that blink when not connected and keep blinking even after connected (with a slower blinking rate), and there are that light up without blinking after the connection is established. So I believe that your Bluetooth module is working fine, and maybe it's caused by something else. OK try to do like this: Connect USB cable between Arduino and your PC, open Arduino IDE, then open Serial Monitor on the Arduino IDE, then try to send any word/letters to the Arduino using the Serial Monitor, then see what happens. The Arduino should display those letters on the LED module once it receives the characters from the IDE.
Daniel Cunha What do you mean by display the message one time? Do you mean the message needs to be displayed for 1 cycle then it disappears? Because the matrix LED works by displaying the last received message that is sent once and maintains the display as long as it doesn't receive any new message. If the answer is yes, then the simplest way is to implement timer or counter that makes the particular message is displayed as long as the timer or counter does not reach a certain limit and when it does, then the Arduino will automatically display blank message. Hope this helps. Thanks!
Hey this is fantastic, well done! I have put together everything and have the words 'Welcome!' scroll across the screen. Also using BT Terminal, I have message in the big black window - 'Connected Successfully' - so the module is visible to my phone. When I try and send text it shows what I typed and says 'Sent:' - However it has absolutely no effect on the matrix words. Any ideas how to get my bluetooth talking to my display? Do I need to worry about having overloaded the Bluetooth or anything? By all accounts the Bluetooth Module looks okay, it has flashing red and blue light when not connected, both of these go solid when it says I am connected...
Mike Smith Hi, did you get any return text in big black window after the text is sent? The return text actually indicates that the Arduino has successfully received the text sent to it. So if you didn't, try to check the connection of the RX and TX pin between the Bluetooth module and the Arduino is correct, which TX of BT module should go to the RX pin of the Arduino and vice versa.
Thanks for the quick reply, sorry have been away. So originally there was no text return at all, however the next day it began fully functioning, sending text and all to the matrix! However yesterday it was back to square one, not working again. I have checked all connections including UNO RX to BT TX and vice versa, can find no reason it has stopped working again. Would you recommend trying another bluetooth module? I have a BT 4.0 HM-10 bluetooth module sitting around, would I need to adjust the Arduino code or app used to get that one working on this project?
Mike Smith Hi, sorry for late replying. Using HM-10 makes you utilize the Bluetooth Low Energy (BLE) technology, and it seems that it is a bit different from the Bluetooth Classic, as described by Martyn Currey at www.martyncurrey.com/hm-10-bluetooth-4ble-modules/: "BLE is not an upgrade to Bluetooth Classic, it is a different system with different intended uses. BLE works in a very different way to the earlier Bluetooth. BLE is designed for low energy applications and achieves this by using infrequent small packets of data. It is not really designed for continuous connections and large amounts of data. For this, Bluetooth Classic is a better choice. In essence, BLE achieves its low power consumption by not being connected very often, unlike Bluetooth Classic which maintains a constant connection." To learn more on this BLE matter, I recommend you to go to the above website as it explains alot there. I believe the reason for your inconsistent Bluetooth data transfer is caused by the BLE module, and if possible, try to use the classic HC-05 or HC-06 Bluetooth module and see the result. Hope this helps. Thanks.
Hi, I don't know why my video description above became truncated. Actually this is the full version of the description: This video demonstrates the steps to build a remote-controlled LED matrix display module, using Android device as the controller. The scrolling text on the LED module was written using BT Serial Terminal available on Google Play. The BT module used in the video is HC-06 while the display is MAX7219 based LED display module. You may get the Arduino code and corresponding libraries here: goo.gl/RUpzQf. Note that I did not build the code entirely by myself, but just modified the code from the others using Parola Matrix library to make this work with Bluetooth communication; many thanks to the original writer of the code. (Updated on 26 Dec 2017) Now you can have the connection diagram for the above circuit here: goo.gl/XzMkoG. Thank you. BT Serial Terminal: goo.gl/Nqg7rx
Hello, this circuit and code works with any boards of Arduino. You just need to change the Arduino boards via Tools -> Board menu and choose Arduino Nano. Be sure to select the correct COM port as well. Good luck!

Sekarang kamu bisa menggunakan pin A2 sebagai pin RX dan pin A3 sebagai pin TX. Maka hendaklah kamu menyambung pin TX dari Bluetooth module ke pin RX Arduino iaitu pin A2 manakala pin RX dari Bluetooth module ke pin A3. Harap itu membantumu. Makasih.
As far as I know, WS2811 is an RGB LED strip, which lights LED in red, green or blue. It is not a Matrix Display hence cannot display text on it. So the programming/code would be different.

Hi, yes. All you need to do is go to this line: int speed1 = 30; and replace the 30 with any lower value you like. Alternatively, you can use a variable resistor to do the scrolling speed control. Connect a variable resistor to pin A5 of your Arduino and comment 4 lines in the code and uncomment 3 lines as stated in the code given.

How to insert in the code, accented characters like Á, Ã, É, Ó, Ô, Ç, etc ... Thank you
