In this project I’ll make one of the easiest PNP and NPN circuit identifiers ever. You’ll see how easy It is to make one! I've also posted on my website a bit of the theory about PNP and NPN Transistors I would recommend you to read it  first.

This project is great to learn more about:
  • Transistors
  • Simple DIY Circuits
  • PNP and NPN Transistors

If you just want to see my project working you can see this video:


Step 1: Parts Required

1x LED
1x Pushbutton
1x 1k Ohm Resistor
1x 10k Ohm Resistor
1x Breadboard
1x 9V Battery (and Battery Clip)
Some Wires

Step 2: Schematics

Just follow these Schematics and you'll be fine! :)

Step 3: Optional Step

I've decided to Solder everything in a Stripboard and that's the result. This step is optional you might want to use only the breadboard.

Step 4: Final Product

hanks for reading I really appreciate you time and support.
Please share my work.
<p>Which legs are collector, base, and emitter?<br>Which resistors go where?</p>
<p>That is awesome</p>
<p>This was helpful for me. Thanks.</p>
<p>Just for other people, if the light turns on without you pressing the button, it is PNP. Otherwise, it is NPN.</p>
this is super helpful for me ..Thanks
Thanks for taking the time to leave your feedback! <br>I'm glad I could help. <br>
The slide swith on bread board on "opitonal step" <br/>Is to on/off all sistem?
