Hello everyone! I hope you are all doing well. I recently have been interested in creating some RGB projects and wanted to start off with a 16 x 16 panel that I purchased along with an Arduino Uno R3. I have been having trouble finding a good tutorial on making this work. I have uploaded the code that I found on a youtube video, but have seen many different ways to wire the Arduino to the LED panel. I have seen all 3 of the red and black wires spliced together to a power supply and the green data in connected to the board. I have read that a resistor may be needed as well to limit the amp flow. I am a person that learns by doing and completing the project with examples and tutorials. Any advice or help would be much appreciated.
Look for Arduino example code for an LED matrix in general. Search for Arduino projects using the kind of LEDs You've got.
I have been searching YouTube, Pinterest, Google, etc.. I can't find any good content that shows how to wire the 16 x 16 LED panel to the Arduino.
Search in the Arduino form. This kind of project has been done many times.
"16 x 16 panel"
By this, do you mean using. . . WS2812 modules -- or what ?
From reading various projects, I am assuming that I can use a 5V, 15A power supply and connect those wires to the WS2812 supplied wire in the middle and to the UNO R3 on the 5V pin? Then connect the data in wire to the selected pin on the UNO (I chose pin 6), the red and black to the power supply? I am also thinking a 300-500 ohm resistor in between the power and LED?
Read about the 1000uf electrolytic capacitor bridging power and ground... have a read as you wait for it to arrive.
And here is a practice page for you...
No, between the Arduino 'output pin' and the module's 'Data In'.
What's interesting with these modules is how the chain goes - some have each row left-to-right, others "ox-plow" fashion (left-to-right, right-to-left,. . .).
You'll find everything out by running the various examples available (Adafruit, fastled, however, whichever).
