Reading a serial ASCII-encoded string.
|
||
|
|
|
||
|
|
This sketch demonstrates the Serial parseInt() function.
|
||
|
|
It looks for an ASCII string of comma-separated values.
|
||
|
|
It parses them into ints, and uses those to fade an RGB LED.
|
||
|
|
|
||
|
|
Circuit: Common-Cathode RGB LED wired like so:
|
||
|
|
* Red anode: digital pin 3
|
||
|
|
* Green anode: digital pin 5
|
||
|
|
* Blue anode: digital pin 6
|
||
|
|
* Cathode : GND
