Background: The design that was created during the ARS X BME project was the jaw accessory, that would go along the jawbone. The vision behind the Arduino project to connect it to the art students project was to add a light into the jaw bone, that whenever the jawbone would light up, the LCD screen would print the color of the jaw that correlated to the light color. For example, if the light turns green on the jawbone part, then the LCD screen would read “The Jaw is: Green”. The light would oscillate between two different colors, based on what threshold was placed on the force sensor or what button was pressed on. For the force sensor code, the colors oscillate between blue and red. For the button code, the colors oscillate between green and red.

TinkerCAD:

In TinkerCAD, the circuit and code was all written around the inclusion of a Force Sensor that would control both the RGB light and the LCD screen simultaneously. How the circuit works is that when the force sensor pressed, at any threshold that was coded less than 200, the light would be blue and the LCD screen would simultaneously read “The Jaw is: Blue”. Once the force applied on the sensor was above this threshold value, the light would be red, and the LCD screen would simultaneously read “The Jaw is: Red”.

Physical:
For the physical circuit, the wires were rewired to include two buttons that controlled the light and LCD screen instead of a force sensor. How the circuit worked was that when one button was pressed, the light would turn red and the LCD screen would simultaneously read “The Jaw is: Red”. When the other button was pressed, the light would turn green and the LCD screen would read “The Jaw is: Green”.
