I have a fan motor that has two green wires. If I want to make a usb fan, the usb has 4 wires, which one do I connect?
Ok the usb has 4 wires-green, white, black and red. It says i'm supposed to connect the usb red wire to the motor red wire, and the usb black wire to the motor black wire. But the motor has only 2 green wires. Which usb wires do i connect them with to start the motor (make a fan)?
