Collin's Lab: Schematics

http://bit.ly/uBjkMR
Schematics are the functional diagram of electronic circuits. With so many designs available on the web, understanding how to read schematics can unlock a world of possibilities for the electronics maker. In fact, if you can read a schematic, you can build a circuit before even understanding how it works!

It's a nice guide, but I wonder why you'd use the physical electron current instead of the technical current to describe how diodes work.

I was about to say his Diodes explanation is wrong, but then I remebered about electrons and current convention, look it up on wikipedia : "Electric_current" then go to 6. "Conventions" and check by yourself.

@lotios611 Thanks for clearing that up

[lotios611]

@DavidLawton93 Even though electricity technically flows from negative to positive, in the real world it doesn't really matter which way the electricity flows. Also, it doesn't matter where the resister is in the circuit, it will have the same effect as long as the electricity follows the same path.

Make:Magazine YouTube account have contact lock so I can't message them :(

[DavidLawton93]

can anyone help me.... I have the tutorial book called Make:Electronics and on page 54, figure 2-48 it shows a basic schematic of electricity flowing from positive to negative and in the first paragraph it says "figure 24-8 shows the flow of electricity more clearly."

My question is, I thought electricity flows from negative to positive? I always put a resistor after negative because I thought if it flows from - to + then the LED needs resistance before it reaches it.

According to World of Warcraft:

A schematic is an item which you obtain, then by "using" it you crumple it up in your hands for 5-10 sec and suddenly you know how to make something by crumpling reagents in your hands in the same way for 5-30 seconds depending on the item.

Silly video games :P

@hellnawnaw in this video ,he is just describing how diodes work, he used electron flow to describe how the "DIODE" works which i think is better, this is basic electronics.. now we dont use electron flow when using logic or microcontrollers. ahahahaa.. now cheers!!

Thanks a lot!!! Very good guide!
