The Emotion Wheel teaches students how to use analog signals in order to control light and movement.
To make this happen, students utilized variable resistance and basic methods of how to use the servo motor with Arduino. In order to complete this project, students had to code using the map ( ) function. This math function takes numbers from one range (the variable resistor) and maps/relates it to the degrees in another range (servo motor).
Simply turn the variable resistor to make the LED light up when the arrow reaches the colored area of emotion you’re feeling. It’s a good way to let others know whether you are Happy-Romantic-Cool-Doubtful-Sad-Angry on this Valentine’s Day!
