Analog input, analog output, serial output
|
||
|
|
|
||
|
|
Reads an analog input pin, maps the result to a range from 0 to 255
|
||
|
|
and uses the result to set the pulsewidth modulation (PWM) of an output pin.
|
||
|
|
Also prints the results to the serial monitor.
|
||
|
|
|
||
|
|
The circuit:
|
||
|
|
* potentiometer connected to analog pin 0.
|
||
|
|
Center pin of the potentiometer goes to the analog pin.
|
||
|
|
side pins of the potentiometer go to +5V and ground
|
||
|
|
* LED connected from digital pin 9 to ground
