Team Safe and Puzzles

Motivation:

The Players are told to steal the Prototype from the Lab. The Prototype will be locked in the safe.

General Idea:

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.

Puzzles:

Puzzle to activate the safe:

Switching levers in correct position
Find the correct resistor to generate the correct voltage

Puzzle to open the safe:

Riddle with numpad input

Protocol to control leds and piezo via mqtt

standart JSON message on topic 5/safe/control with data = "x:y". x is color and y is the mode.

LED_MODE_ON 0
LED_MODE_OFF 1
LED_MODE_PULSE 2
LED_MODE_BLINK 3
