Analog input, serial output
|
|
|
|
Reads an analog input pin, prints the results to the serial monitor.
|
|
|
|
The circuit:
|
|
|
|
* Potentiometer connected to analog pin 15.
|
|
* Center pin of the potentiometer goes to the analog pin.
|
|
* Side pins of the potentiometer go to +3.3V (VCC) and ground
|
