Intro to Breadboard Electronics
1 Nov, 2009 | Posted by nancyperez | under Podcasting (Audio)
In this podcast, Bre Pettis shows you how to set up a breadboard for power and then play around with electronics on it Note: In the podcast, I mention Charles Platt’s article is from Make: volume 11. Its actually in Make: Volume 10.

It should be just in front of the first led. I did something like that in class and I just put it in front of the first one.

(the rest of it)
It is because they have an “on voltage” (you can see it at its current-voltage curve). One or two may have a slightly different “on voltage”, less than all the other in parallel with it. This will burn this LED, as it will draw a lot of current. You wil end up with a fried LED !…

No you don’t need to. Of course it still works. But you can even place this one resistor everywere you want in between (I mean in succesion to the LEDs, of course). You don’t need many resistors.
***BUT*** If you want to to power LEDs in parallel, YOU NEED A PESISTOR IN SERIERS WITH EACH AND EVERY LED SEPERATLY and NOT just one resistor in front of the whole bunch of parallel LEDs. This applies ONLY TO LEDs, because of their semiconductor behaviour.

1 question:
if i have a resistor and leds in succesion, do i need to have a resistor in between each led or just at the front of the first led???

hey are you saying that on the diagram this guy is showing that the current flows from right to left, because he is saying left to right as the derection the diode is pointing to is that way, i am just asking as you have said that the guys hand movement was wrong, but, to my knowledge he is correct, flows left to right, same way as the point on the arrow of his diode diagram, surely this is common sense, or am i wrong

Well done, except your diode symbol ( or your hand movement ) is backward.

4:38 “alright now you can see how easy it is to make a circuit on a breadboard as i hold up this overly complicated noise maker” lol

i enjoyed watching your video, thanks

Maybe both, you need something to drive the speaker!!

in technical terms, Ground is the lowest possible voltage that leads back to the source 0V (this is for one way current Direct Current(DC)) but for AC(Alternating current) the ground voltage is usually negative due to the two-way nature of AC.

Ground is the minus.

thx for the info, butyea just a tad confuzzled
gerjaison | November 1st, 2009 at 11:10 am #
Finished you ass?
Easy mate! Your project could just use a 555 timer!

Technically, the GROUND is the lowest potential for a system return path.
Practically, E.g. a 9V battery, the ground would be your negative terminal as it has the lowest potential point.
For your wall Socket, its alittle more complicated, becoz the ground could be either Active or neutral pin since it is an AC circuit (sine wave).
Some may say the earth pin have the lowest potential but it is mainly for safety purpose (leakage current) and it doesn’t affect the sys operation.
Confused?

You can get them at radio shack
snowman4839 | November 1st, 2009 at 11:10 am #
that’s not a stupid question. I don’t quite understand it either. Anyone have an answer?
InvalidUsername5 | November 1st, 2009 at 11:10 am #
this may be a really stupid question, but what exactly is ground?

were do i get a bread board
vladpuha | November 1st, 2009 at 11:10 am #
Hi where do I get your magazine and pdfs. Thank you for video, it is really nice and relevant - all of them.
sabri1rk | November 1st, 2009 at 11:10 am #
awesome , ,great ,
supersanchez1991 | November 1st, 2009 at 11:10 am #
where can i get those magazine man? especially that one the one you show in the video because i want to know about 555 timer i am new at this i i would like to know where the wires go and all that. please respond. i want that magazine so bad.
jegoll | November 1st, 2009 at 11:10 am #
its 3rd time today i stumble a vid from makemagazine
cycoslayer69 | November 1st, 2009 at 11:10 am #
Ive got an assignment in physics where i have to make a house alarm that sounds after 10 seconds , this vid might come in handy : )
