Have you ever wanted to understand how to use transistors in your circuits?
Well now is your chance.
A while back I wrote about how to create a light that turns on and off automatically, and I wanted to send it to you:

If you’ve gotten the introduction to how transistors work this is the logical next step.
https://www.build-electronic-circuits.com/how-transistors-work/
The circuit shows you several basic electronics concepts in action, like:
how the transistor can turn something on and off
how a sensor works
how the voltage divider works
how the resistor helps the LED not to blow up
Keep on Soldering!

Can you pls. Tell me a transistor that switches on at 9v ang closes at 8v.is there a transistor that works that way??
Needed your help for my project..

8-9V from base to emitter? Not that I’ve heard of…
Best,
