Description:

Hi,
I was trying to put LEDs on my Helmet and I realized this issue occurs ar random, I have several ESP-01 and Node MCU lying around, and it happens with all of them at times, and some never.
The flicker seems to be very random, the only times I have fixed it is by using the USB port on the Node MCU to power it up, and if I use the Vin pins the LEDs behave very erratic at low brightness or patterns like Pacifica.
The setup I have is at standard ie. 330-ohm Resistor and 1000uf 10v Cap also is present, so far while using my Powersupply and 2A Samsung or any brand phone charger recreates this problem. Here's a video showcasing the issue.
Please note Before blaming the wiring or LEDs I have used a different NODE MCU to check the LEDs the worked fine even on low brightness. It's not the ESP or the LEDs cause the same happened even if I use 30 LEDs or 900 Of them.
I really need some help, I'm sure many others would have faced similar issues, I'm not able to use any effect on low brightness
