Six LEDs in a row, left to right: GPIO5, GPIO6, GPIO13, GPIO19, GPIO26, GPIO21. Light every third LED and march the pattern to the right, one place every 0.4 s:
| time | lit |
|---|---|
| 0–0.4 s | 1st and 4th (GPIO5, GPIO19) |
| 0.4–0.8 s | 2nd and 5th (GPIO6, GPIO26) |
| 0.8–1.2 s | 3rd and 6th (GPIO13, GPIO21) |
Then back to the 1st and 4th at 1.2 s, and so on forever. All other LEDs are off.
Tip: LEDBoard(5, 6, 13, 19, 26, 21) lets you set all six at once with board.value = (1, 0, 0, 1, 0, 0).
