LED lights, or Light Emitting Diodes, were invented in 1962 by Consulting Scientist Nick Holonyak Jr, at a General Electric Laboratory in Syracuse, New York. At the time, he predicted that they would replace Edison's standard incandescent bulbs. Now, they are indeed slowly replacing the inefficient, energy hogging, high drain light bulbs.
A few years back, at school science fairs, students would struggle to light one of those blasted lights with 5, or even 6, lemon batteries. Even then, they would only glow very dimly, NOT impressing the millions watching. Well, maybe not millions, but, you get the point.
Now, those mini heaters are mostly replaced by LEDs in science fairs worldwide, but still, it would require 3, or 4 lemons, to light one.
I, being a student myself, set out to change this, set out to change the world! I forgot the story of how I thought these up but oh well!
Anyway, here I will teach you how to make tiny batteries to power LEDs.
