CJMCU 64 Bit 8×8 RGB LED Driver Board Stuck on One Color

[Shraddha]

Hey everyone,

I'm having a bit of trouble with my CJMCU 64-bit 8×8 RGB LED Driver Board. The LEDs light up, but they won't change colors like they're supposed to. Hoping someone here can help me out!

Here's my setup:
Board: CJMCU 64 Bit 8×8 RGB LED Driver
Microcontroller: Arduino Uno
Power Supply: 5V 2A
Library: Adafruit NeoPixel

The LEDs are stuck on one color and won't change no matter what I do. I've checked my wiring and code a million times, but still no luck.
I used example code from the Adafruit NeoPixel library to make sure my code isn't the issue. Swapped out the data and power wires just in case.

Here's my code-
#include <Adafruit_NeoPixel.h>

#define PIN 6
#define NUMPIXELS 64

Adafruit_NeoPixel pixels(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

void setup() {
pixels.begin();
}

void loop() {
for(int i=0; i<NUMPIXELS; i++) {
pixels.setPixelColor(i, pixels.Color(255, 0, 0)); // Red
pixels.show();
delay(500);
pixels.setPixelColor(i, pixels.Color(0, 255, 0)); // Green
pixels.show();
delay(500);
pixels.setPixelColor(i, pixels.Color(0, 0, 255)); // Blue
pixels.show();
delay(500);
}
}

It could be a faulty LED or board, or maybe the NeoPixel library isn't playing nice, or the data signal might be getting messed up!
Any tips or ideas would be awesome!
