Diodes

Diodes were an interesting type of circuit componant.

I already knew a bit about them which helped me a bit through the subject.

Diodes are an electrical componant that stops power surges or just basic current flow from flowing back from its source.
Diodes only allow current flow go one way and this prevents surges stopping any electrical device to short out from Backflow.

Thats basically all i can say about Diodes as thats all they do.

The way I learnt this about Diodes this time was that the class told to make a Logic probe.

We had 2 LED's (light emitting diodes) Some wires, some heat-shrink, a brass rod, 2 resistors, 2 alligator clips and a plastic tube for insulation.

we soldered the LED's on the wires, one wire per LED and insulated some contacts on the brass rod with heat shrink the resistors were soldered onto the wires and the wires were soldered onto the brass rod. the alligator clips were attached to the other ends of the wires and then we were done. (A brief explanation on the build but you get the jist of it)

we tested the Logic probes on powered volt meters to see if they worked, thus they did, when theres a positive power source the logic probe lights up green and negative lights red.
