2N2222 NPN Transistor as a switch - Arduino example with LED Flash

How to use the 2N2222 NPN transistor as a switch. The video will go over the use of the 2N2222 transistor to switch a bright LED Flash on and off. We will first switch the 2N2222 using a push button, and then will transition to test with with an Arduino. *Note that the LED flash used in this example is a ready-to-use component with a built-in ...
