My project is based on the idea of relaying an emotion of the user based on the input that they feed the Arduino.
The little monster expresses emotions that are directly related to the speed at which the user presses the button, and the intensity with which they press it. The ‘intensity’ is calibrated by the potentiometer connected to the board. On the setting with high intensity, the faster the user presses the button, the angrier the monster gets. The slower the button is pressed on high intensity, the sadder the monster gets. On low intensity, the faster the button is pushed, the more scared or nervous the monster gets while the slower the button is pushed, the more tired he gets. In both intensity settings, if the user pushes at a medium pace the monster will be happy.
