Lesson12.Control the MOSFET as a Switch
As MOSFET has a high speed response and high stability, we usually use it as a switch in some
application, this lesson will teach you how to control the MOSFET on/off. Connect the crowtail-
MOSFET to P0 interface and connect one LED to the output terminal of the MOSFET, then upload
the code into micro:bit, you will see the LED blink.
