How to Identify PNP and NPN Transistors (with a Simple Circuit)
Intro: How to Identify PNP and NPN Transistors (with a Simple Circuit)
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:
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
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

Which legs are collector, base, and emitter?
Which resistors go where?

Just for other people, if the light turns on without you pressing the button, it is PNP. Otherwise, it is NPN.
