So far what I learned in LED is.... that you can make a simple circuit. Also that you can light up to 4 LED lights to 1 battery. A resistor is used to not stop the energy flow but use less energy. Also with the LED light you can not connect a positive to a positive or the battery will run out. Also with a string of Christmas lights that with a wire cutter that you can take off a USB cable. Then I striped the cable and found the 2 wires that go in and out. The side on the left was bigger than the side on the on the right so I connected the bigger side on the positive side of the coin battery..... the lights light up!!!!
