Good afternoon,
I am not sure if my error is somehow in the Blink example or if I accidently missed something in my attached snippet of my circuit design. My understanding was all I needed was a 300 Ohm resistor from the datapin of the Atmega328PB in series to the DataIn of my first LED (LED0). I have successfully burned the bootloader to use the internal clock (8 MHz) before anyone points out the lack of a crystal for the external clock.
With the code below (from the FastLED Blink example, I just removed the comments to not have it take up so much space here) I am able to turn on as many of the LEDs as I want (currently I have it back down to 1, but if I set it to 4 all 4 will turn on when I program this using a programmer via ISCP (and the Arduino IDE) however that is all that I can get to happen. It will not change colour, it will not turn off the LED until/unless I upload a new version of the code using less LEDs.
#include <FastLED.h>
#define NUM_LEDS 1
#define DATA_PIN 10
// Define the array of leds
CRGB leds[NUM_LEDS];
void setup() {
FastLED.addLeds<WS2812B, DATA_PIN, RGB>(leds, NUM_LEDS); // GRB ordering is typical
}
void loop() {
// Turn the LED on, then pause
leds[0] = CRGB::Red;
FastLED.show();
delay(500);
// Now turn the LED off, then pause
leds[0] = CRGB::Black;
FastLED.show();
delay(500);
}
