| - | Take a look at the DigiRGB example for more advanced usage. When using that example you must set your board type as Digispark (Tiny Core) for it to work. | + | **PWM Note:** While the red and green LEDs are connected to pins that support PWM, the blue LED is not - this is because the third PWM pin is used by the USB communications and we figure most will want to use the RGB shield with USB communication. See Examples->DigisparkRGB->DigisparkRGB or Examples->DigisparkUSB->DigiBlink for examples of using software PWM for pin 2 (blue LED). |
| + | |||
| + | If you are not planning to use USB communication: If you want to connect the blue LED to P4 instead of P2 - flip the shield over and you'll see two solder jumpers, one has a little trace connecting its two pads, the other doesn't - cut the one with the trace and bridge the other with solder. This will disconnect the blue LED from P2 and connect it to P4. | ||
