Have you ever wondered how flashlights work? I have. And I didn’t figure it out until yesterday. The inside of a flashlight is exactly like the circuit’s we’ve been making for the past week. So the way to make a flashlight is to make a simple one LED light circuit, put it in a PVC pipe, flick the switch, and there you go, you have your flashlight. But are not taking a direct path to the flashlight. First we have to draw a diagram. I am currently working on my diagram and from what I can see it will actually be a working flashlight!
