Basic Electronics (Project Help)

[asad3man]

Okay. I am student of CS. And it's in our course.
I am about to complete Basic Electronic course. I am absolutely dumb in Electronics. Just have basic info of circuits. What i am thinking to do for my project is that to make a Diode Polarity Indicator. It's basic and i know it. I just want to get help from you guys. How can i make it. I mean. I am little confuse for what i am thinking. I am thinking :

To place 2 LED's which will show polarity. If the diode is forward biased it shows green if reverse then red. Well what i want is that a 'place' where we can change diodes everytime.
'''Jese aik circuit hai beech mei jaga ho jahan diodes ko rakh kr check kiya jae'''

^^ This is what i am unable to point out. What will be the circuit for it.

I don't quite understand. You can make the circuit but you can't figure out a place to put the diode at? What are you using for a circuit board? Breadboard? PCB?

yup I don't understand what the OP is saying either. [MENTION=38525]asad3man[/MENTION] can you make a drawing or something to illustrate what you what help with

can you please elaborate more? what are you trying to say? The thing is, LED itself is a diode so you would be using a led or mainstream diode that is used as current limiter?

If I understand you correctly, you want a place where you can remove and insert diodes in a circuit to check their polarity?

Pretty easy. Just use a breadboard mate, remove and insert as you like. If you want it on PCB, use female headers.

Why not simply use a single diode. If it lights up, battery is forward biasing it. If it doesn't then it is reverse biased. But then again this isn't much of a project. Remember to use a small resistance in series with the LED (around 200 to 1K ohms) to limit the current.

Project done. This can be close. [MENTION=39471]Blastwave[/MENTION]

BTW I wanted to glow up LED on both color i got bi-color LED though.
