On the Subject of Even Or Odd

Soloing this one is the way to go.

The module consists of a timer, a display, and two buttons beside the display.

To initiate the module, press the display. The timer starts at 30 seconds and will countdown after pressing the display and the display will show a random number between 0–9.

The number that appears will be colored either green or red. If the number is colored green, press the correct button label for that number. If the number is colored red, press the opposite button label for that number.

For the first number, press the correct button.

After answering the first number correctly, the number that will be used for the module is the sum of the previously shown number and the currently shown number. If the number is above 9, subtract 10 until the number is between 0–9. After answering the second number correctly, the number that will be used for the module is the sum of the previously calculated number and the currently shown number. Perform the previous steps about 8–12 times to solve the module.

Pressing the incorrect button or running out of time will cause the module to give a strike and the module to reset.
