BC547 NPN Transistor as a switch - Arduino example with LED Flash

Описание

How to use the BC547 NPN transistor as a switch. The video will go over the use of the BC547 transistor to switch a bright LED Flash on and off. We will first switch the BC547 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 resistor, which is why a separate resistor is not needed.
