How to Build Electronic Circuits : How to Make a Schematic for Your Electronic Circuit Project

in what profession you have to be to know how to build a circuit board.

who the fuck cares if the door is open??? thumbs up if you agree

[TheDslide]

use 9v batterie with a resistance of 600 Ω for a LED of 15mA

[Probewitch]

It would be so cool to just draw the components, and have that be a working circuit. I can do this for resistors, anything else is tough.

yep its a reed switch....moody video tho...

[GreenAce92]

wait how does the magnet connect the circuit? is there a wire attached to the magnet?

BOOOOOOOORRRRIIIINNNGGGGGGGGGG­G

[cheezeheads]

you should use a normally closed switch or smthng

[warlord90210]

I'm not quite sure how this senario is being played out...

Do you have a magnet on the door or something?

How would you indicate that the door is open?

I'm trying to get into circuits... I'm curious.

[kaviaari]

You could mount the magnet to the door and when it's up (ie. open) reed would turn on.

Reed-switch is just two sheets of iron mounted in a closed glass container. When a magnet comes close enough the two will touch.

Elecric systems have three main sections: input, process and output.

Here input would be door being open, process would be turning on the led and output then be the led emmiting light.

may i ask what is that thing you magnetizing?

[Catkill666]

Looks to be a reed (or read) not sure of the spelling , switch

[sdcombo112]

Yes the correct name is a reed switch. It acts as a switch that completes the circuit when a magnet is near it.

You should put a link on this page to the first part of you this tutorial, and a link to the second on the first.
