Are you using the transistor yet?

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.

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!
