Ponder – Adam Ahmed & Amixa-Ray Calzado

Ponder is a chair that encourages people to take time out of their day to ask themselves a mindful self-reflection question, that is printed on a ticket. We hope each person captured an essence of time and thoughtfully look forward positively. There is no particular situation we’re detecting, but rather the presence of a user. The self-reflection questions are completely randomized, allowing for people to be asked questions that they may not have thought about before. The point of this object is to allow users to reflect and be more aware of themselves and their well being. The novelty of Ponder is that it may not fully grasp the moment of every person, but it may inspire them to become better humans overall.

For detection, we used a Force-Sensing Resistor (FSR), within the cushion seat. When pressure is applied the resistance value (in ohms) to the Arduino. In our code, we are detecting values greater than 200 ohms. Which will cycle into the loop to triggering the Adafruit Thermal Printer, the actuator, to process a ticket. One ticket will print as long as the user is still on the cushion seat, once they leave the code will cycle through the loop and print again when someone else is seated.

#include <Wire.h>

/* FSR testing sketch. 

Connect one end of FSR to 5V, the other end to Analog 0.

Then connect one end of a 10K resistor from Analog 0 to ground

Connect LED from pin 11 through a resistor to ground
