The Players are told to steal the Prototype from the Lab. The Prototype will be locked in the safe.
After Entering the Lab Room the safe will be deactivated (red LED light). The players first have to supply the safe with power by solving a puzzle (see section puzzle). This action will change the light color of the safes LED to orange and activate the second puzzle. This puzzle will ultimately open the safe to give access to the prototype.
- Switching levers in correct position
- Find the correct resistor to generate the correct voltage
- Riddle with numpad input

standart JSON message on topic 5/safe/control with data = "x:y". x is color and y is the mode.
Colors (x):
- LED_COLOR_WHITE 0
- LED_COLOR_RED 1
- LED_COLOR_GREEN 2
- LED_COLOR_BLUE 3
- LED_COLOR_ORANGE 4
Mode (y):
- LED_MODE_ON 0
- LED_MODE_OFF 1
- LED_MODE_PULSE 2
- LED_MODE_BLINK 3
- LED_MODE_PIEZO 9
For LED_MODE_PIEZO the color parameter is the time of the buzzer sound in seconds.
examples:
- "{"method": "trigger", "state": "on", "data": "3:0" }" => Turns blue LEDs on.
- "{"method": "trigger", "state": "on", "data": "4:3" }" => LEDs orange blinking.
- "{"method": "trigger", "state": "on", "data": "5:9" }" => Buzzer sound for 5 seconds (max value: 9)

- Close the safe
- Pull out the resistors and place them in front of the puzzle
- Put the safe datasheet (back) on the table
