Digital Port
The digital port on the PiSmart can control the high and low electrical levels though digital
values (1 and 0). It can also judge the high and low of the input voltage and transfer it to
digital value (1, 0). In the following experiment, we will use the button switch to turn on and
off of the LED light, in which we can better learn its working principle.
Turn on and turn off the light
In the experiment, when you press down the button (means the input is high level "1"), the
LED will be on. When there is no button down (means the input is low level "0"), the LED will
be off.
Similarly, you can also drag out the block under PiSmart and use the
block to set the input value of the digital port.
