The prop controller has 4 relays. You can connect indicator lights, magnetic locks or any other electric device to the relays. The relay functions are as follows:

Relay 0: Turns on when a scale is detected

Relay 1: Turns on for X seconds when a weight that is below the target weight is detected

Relay 2: Turns on for X seconds when a weight that is above the target weight is detected

Relay 3: Turns on for X seconds when a weight that is equal to the target weight is detected

(values for X are programmable and can be changed to best suite the needs of the game)

Audio function is also included and audio files will play for different puzzle states, including when a weight that is too high or too low is detected, and when the puzzle is successfully solved.

Please Note

• The maximum weight of this prop is 10 pounds
• A USB Flash Drive is required to load settings onto the prop controller
• The scale powers off after 3 minutes of inactivity. Making the turning on of the scale part of the puzzle avoids this issue
