2. Pinout
Pin
Description
A0
Analog signal output pin
G
Ground
+
Power(5V/3.3V)
D0
Digital signal output pin
3. Example
We will use three example to show the different function of this module.
Example 1 show you how to use the digital pin(D0), Example 2 show you how to use the
digital pin(A0), In Example 3, we can try to combine this two function into one experiment.
3.1 Example 1
This example shows you the digital pin function, connect Pin12(Arduino) to a LED light,
and connect this module as below, and upload the code.
