- This is the final individual item in my Halloween AI playlist before I start assembling the project. The final piece is this 64x32 LED Matrix Display. Here's the parts list:
Parts:
Raspberry Pi 4 with power: No link
64x32 RBG LED Matrix: www.adafruit.com/product/2278
RGB Matrix Bonnet for Raspberry Pi: www.adafruit.com/product/3211
5V 4A (4000mA) switching power: www.adafruit.com/product/1466
Fame DC Power adapter - 2.1mm terminal jack: www.adafruit.com/product/368
To clone the github: git clone github.com/hzeller/rpi-rgb-le...

Note that this DOES NOT WORK WITH A RASPBERRY PI 5 (at least rn). The software on github hasn’t been updated to work on it yet, so go for an earlier model
Thank you for the contribution. I will pin this comment for the time being.
This video was a huge help in setting up my own pi, thank you!
I’m glad to hear that!!!
@@coleisfinagle this video was on TikTok?
@@BrandonJacobson i have a question. whenever i run my code I get a thingy saying FYI : not running as root which means we can't properly control timing unless this is a real time kernel. Expect color degradation. Consider running as root with sudo. Is there a way to fix this?
@@caxew i gotchu, type root before your code right before your execution type sudo, if your using an application like a code editor there is ways to run from root every time in settings it varys by app. aditionally if you set up your code file to be run on boot you can just run from sudo every time
Thank you so much. This is the only video that explains the raspberry pi software part.
I'm glad it helped!
Thanks a lot Brandon! I have the Adafruit RTC Hat instead of a Bonnet... Do they function with the same code or are there any adjustments needed?
Good tips!
I want to use a display to check the time.
You just have to find a good time API and it should be easy.
This may not relate to the video directly, but using the set up you currently have is it possible to add another module like a hall effect sensor?
thank you so much ! thats was really helpfull!
I’m glad it helped!!!!
Very illuminating. LOL. Been looking at LED matrices for a friend's project. He wants to use Arduino though. Thanks.
There's actually more Arduino support for Adafruit products than Raspberry Pi/Python support.
@@BrandonJacobson Indeed!
Thank you very much for your video, it helped me a lot. In case I want to run C language files, how should I install it?
For Python you used:
make build-python PYTHON=$$(which python3)
sudo make install-python PYTHON=$$(which python3)
and for C language?
Great help thanks. How can it run from boot? I'd like to display a message on the board at a show but don't want to take a monitor, keyboard and mouse!
Thanks for the video. For some reason, my text is all screwed up? Any ideas, sort of looks like a different language but not?
cool! saw this on reddit. doing a similar project (not with AI) but want to make a dashboard like tidbyt with mine. wonder why you use a raspberry pi 4 when you could use raspberry pi 0? seems like a waste of resources
The LED matrix is just one component of this project. Assuming the sound board doesn't interfere with the LED matrix with the pi 4, I'm going to be running Speech Recognition, Speech-to-Text, an M5 video recognition camera, and NLTK together. I'm actually thinking the the pi 4 might not be strong enough.
@@BrandonJacobson since the HAT takes up all the gpio ports, I'd probably run the matrix on a Pi 0 and the other stuff you have planned on a separate Pi 4 (i'm no expert so take my recommendation with a grain of salt). very cool stuff though, looking forward to stuff you have planned :)
If i made a python code that displays the time using tkinter can i run it on the led display?
Awesome! Do you know if an ESP32 would work for this?
Thanks! I just did a quick Google search and it looks like it can definitely work with ESP32.
is there a way to center the image instead of it being on the left?
Hello. I have Pi 3B v1.2 and i have connected my waveshare-p3-64x64 matrix according to the connection showed in github repository. But it is not working properly like it shows square in some lines then in middle some lines are off and that remaining sqaure is below those lines and it looks like it is skipping those lines in middle. Do you know any solution?
Hey bro I’m using the 64x64 with raspberry pi 4. My matrix is bugging out when I use it. Any tips? Did you figure it out? I have a school project with this due soon. Help greatly appreciated
@@user-ok1kc1yi6t what do you mean by bugging out. Can you please explain.
I'm having the same issue, Did you figure it out?
@@Hannah-RoseFleishman Yes, you have to change one variable value. But I forgot that variable for now.
@@AkashIsHere.19 please let me know if you remember! would be a great help
Do you have to do any soldering?
No, the hat sits right on top of the Raspberry Pi; however, be careful because it's not very stable. I think I broke my hat pressing down too hard on it.
Hi thanks for the vidéo, I'm trying to do the cabling without adaptator. I'm using a raspberry PI 3 model B V1.2. And it didn't want to display a single LED 🥺
Are you getting an error or does the program run successfully but nothing displays?
I dont see the python file on the github
Opshin? What is an opshin? What is installashin?
It's Data, not Data!
You should use a good microphone someday
Thank you for the feedback. I plan to get a real microphone this month actually.
Bad tutorial
