Press the button in the center to start the module. After this, the button will flash 4 colors each for half a second, with breaks in between.

Use the below table to figure out when to press the button. Use the first color flashed by the button as the column, and the first applicable row as the row.

The sequence does not loop. Pressing the button at an incorrect color or waiting for all 4 colors to pass will incur a strike and demand another press to restart the module.
