Hello everyone! I'm wanting to convert 40 fairy lights to USB and need to know what resistor I should use and where to place it as I am a noobie! I have 3 seperate sets (120 fairy total LEDs) of these that will plug into a 4 port USB outlet. Here are the specs of the USB charger outlet: total output of 5V/5.8A; quad (4) Type-A USB ports; up to 2.4A per USB port.
I bought three USB-A pigtails already with a two wire connection. Fairy lights are also two wire.
