|
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
