AnalogReadSerial
|
||
|
|
|
||
|
|
Reads an analog input on pin 0, prints the result to the Serial Monitor.
|
||
|
|
Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu).
|
||
|
|
Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.
|
||
|
|
|
||
|
|
This example code is in the public domain.
