basic WS2811 string test pattern that runs through some color combos, then continuously sends a full-white (RGB 0xFFFFFF) signal to the chain every second. this is to allow for breaking the data or power connections somewhere on the chain during test pattern run time

| -------------------- | |
| pin 2: LED Strip #1 OctoWS2811 drives 8 LED Strips. | |
| pin 14: LED strip #2 All 8 are the same length. | |
| pin 7: LED strip #3 | |
| pin 8: LED strip #4 A 100 ohm resistor should used | |
| pin 6: LED strip #5 between each Teensy pin and the | |
| pin 20: LED strip #6 wire to the LED strip, to minimize | |
| pin 21: LED strip #7 high frequency ringining & noise. | |
| pin 5: LED strip #8 | |
| pin 15 & 16 - Connect together, but do not use | |
| pin 4 - Do not use | |
| pin 3 - Do not use as PWM. Normal use is ok. | |
| This test is useful for checking if your LED strips work, and which | |
| color config (WS2811_RGB, WS2811_GRB, etc) they require. | |
