| This is a sample app which drives a RGB LED using PWM. |
| |
| There are three LEDs of single color in a RGB LED. The |
| three LEDs will be driven by a pwm port each. The pulse |
| width for each pwm port will change from zero to period. |
| So, the brightness for each LED will change from dark to |
| max brightness in 11 steps. The three "for" loops (one |
| for each LED) will generate 1331 combinations and so, |
| 1331 different colors. The whole process will repeat for |
| ever. |

| Arduino 101 |
| =========== |
| You will need to connect the LED pins to PWM0, PWM1 and PWM2 |
| on arduino 101 via the shield. Depending on what kind of RGB |
| LED you are using, please connect the common cathode to the |
| ground or the common anode to Vcc. You need current limiting |
| resistor for each of the single color LEDs. |
| |
| The sample app requires three PWM ports. So, it can not work |
| on Quark D2000 platform. |
