Electronics Help

Hi,

I'm doing electronics as one of my GCSEs options and i don't understand a piece of my coursework. I will have to draw 2 circuit ideas but i don't understand it. Why do i need circuit ideas for my project? and will i need to draw circuit ideas that i will use for my project?

Oh, i don't know if this will help or not but for my project, i am making a game buzzer. When the player presses the button, a LED and a buzzer is activated until the player realise the button.

If this is confusing, i try and edit it to make it simpliar for you to understand.

Thanks

You have to draw a circuit diagram(I'm afraid I don't know what a circuit idea is, so I'm going to guess that you actually meant diagram, if I'm wrong I apologize.)? (a bunch of connected symbols to show what the circuit will look like when it's actually made.) If so I can assure you that they are useful, they help you plan out exactly how everything is going to work, for something simple like a buzzer the use is hard to see, but when you start making a bunch of LEDs flash on and off in sequence you're going to praise the man who first came up with the idea.

As for how to make one, that's rather hard to say over the internet, but I'd assume you were taught how in you're course, were you not?

Thanks for the reply.

Well, we haven't actually been taught electronics properly. The thing is, we have a bad teacher. He thinks we know everything about it already and gets angry if we don't understand it properly. Also, he always talk to us in a complicated way so we don't understand.

Anyway, thanks for your reply and I think I need to do that for my coursework.

Thanks again

Here's Wikipedia's page on circuit diagrams. Assuming you know what all of the parts do, that should help.

Oooo. O_o. Thats interesting. Thanks for that link, i will use it for help.

Do you mean an actuall diagram or an idea as in drawing the components you will use? I also do GCSE electronics so I might be able to help.

For the two, you probably want:
A. a circut going from the battery to the switch, then to the buld then to the buzzer, then back to the power supply (battery). This is called a series circuit, if you need to know that. Not as efficiant as the next one.
B. a circuit that goes from the power source to the switch, then splits, and one line.wire goes to the buzzer and one to the bulb. then they rejoin, and return to the power source. This is called a parallel circuit.
I'll try to make and upload an imag if you want - for a diagram.

If you want both, the led and the buzzer, to work, then the two circuits are equally efficient. The parallel one is more efficient if you want your circuit to keep going even if some of the components fail. It depends on what you want your circuit to do...

Wow. Thanks for all of your replies. I will use all the help from you guys.

Yes please, if that is ok with you O.E.

I think is circuit ideas Mak.

nice sig ;0)

If you need any help actually drawing the diagrams, let me know. We could probably do something on MSN sometime.

I took a graduate-level electronics course (PHYS645) which was very useful. My final project was a MASSIVE circuit which used infrared (pyro) sensing to count people going in and out--both analog and digital designs.

Cheers BBD!!!

Well, i'd managed to complete that piece of the coursework thanks to you guys!!!

Cheers for the help and advice
