| Apr 5, 2023 at 17:49 | comment | added | nmr | Yes, Resistor was very close to the LED and it was making the LED really hot. | |

I have added the schematic. I built the circuit in a perf board. The LED side and the chip resistor was about 4mm apart.

| Apr 5, 2023 at 15:33 | comment | added | Justme | Based on description something was wrong if a green LED damaged with 1k in series to a 3.3V supply. Maybe something was connected incorrectly. Please draw a schematic what you had. | |

| Apr 5, 2023 at 15:31 | comment | added | Jonathan S. | Could you draw a schematic showing where you accidentally put the second resistor? Additionally, was the failing resistor physically close to the LED? | |
