Thats the Spot!


Hardware Components Used




That’s the Spot! is an interactive game where the interactor controls a servo motor with a soft potentiometer. The motor head collides and bends a flex sensor. As the flex sensor bends, the LEDs will light up from yellow to green. If the interactor discovers the “spot” and holds the position, the piezo buzzer will play a jingle. After the interaction, the system resets and a new spot is selected for a different experience.

As they interact, the interactor should feel determined. They should feel the struggle to find the correct spot to complete the sequence. The personal value of the piece was the challenge of the flex sensor and the board design. Since the breadboard is small, I struggled to create a smooth interaction between the servo and flex sensor. Besides the design, the flex sensor sensitivity is short. I mapped and constrained the values for the interaction to work correctly.

Possible idea for the structure:

I envision this piece as being contained within an acrylic structure with one side being brass. The side of brass would be the interface with the soft pot and LEDs connected too. The rest of the piece would be a clear shell which will allow the interactor to view all the working parts interacting with itself. The style would be a mix of steampunk and sciFi.

To fill the negative space within the shell, there would be a mess of colorful wires. Example:
