Let's Explore
A light-emitting diode (LED) is a semiconductor
device that produces light from electricity.
1 - ON or 0 - OFFPin-0 (P0), Pin-1 (P1) or Pin-2 (P2)
- Which pin is it connected to?
You can control an LED that is connected to the
micro:bit using [ digital write pin __ to __ ] block
from the [ Advanced - Pins ] category.
An LED is an example of a digital output device.
It has only two possible states - ON (1) or OFF (0).
It has a positive terminal and a negative terminal.
For the LED to work, the negative terminal
(shorter leg) must be connected to pin-GND but
you can connect the positive terminal (the longer
leg) to either pin-0, pin-1 or pin-2 of the micro:bit.
