Think of this like cats and dogs fighting- you have to keep the two lines separated!) (If your positive trace goes directly to your negative trace, then the electrons will not be forced THROUGH the LED. Does the positive circuit trace ever come in contact with the negative circuit trace? Make sure to leave a gap under your LED.It is important to note that electrons are lazy and if they find an easier way to close the loop, you will short your circuit and your LED won't light up! So this means if you are having trouble lighting an LED with this simple circuit template, you should check: With paper circuits, we say "Hello Light!" as that is the simplest thing that a paper circuit does… light up a light! We will first need to print out a template on a piece of paper. It’s a good way to imagine it is that you are taking the pulse of your project to make sure it is alive and well. In the engineering world, we like to type "Hello World!!” as our first line of code.
