Sorry if this is a dumb question, I am new to electronics and was looking at diagrams of USB cables and wondered,
"Could you use the low voltage data wires on a usb and a MOSFET or something to control the voltage from the higher voltage wires to make an LED blink on and off?"
I have been searching online and could not find much (maybe that's a bad sign) I have a cable that splits the 4 usb wires and connected them to a bread board and can turn on the LED with the +5V and -5V wires, but I'd like to know if I can use the other wires to control it?
Any advice is appreciated! Thank you
