Intro:

Since I get the assignment that I need to create some stuff and put it in a public space to collect a series of data, I decide to use a soft toy like Teddy Bear and put 5 sensor in different part of its body, for example putting one in the left hand, one in the right hand and the same with the legs, so in this case I can know where is the spot on the Teddy Bear that people usually want to interact with most.

But, there is always a BUT. Since a feather board has only one analogue input that it can actually grab the data from one sensor only. So I GIVE UP the five sensors idea. Instead, I put one force sensor in the Teddy Bunny’s belly, just to test if the passengers will like to press the the toy. And that is it~~~can you feel the breeze on your face when you just decide to give up on some big idea and you are still alive!!!

Working theory:
There is a force-sensitive resistor connect to an Adafruit Feather. The Feather polls the sensor every minute, and whenever the pressure measurement has a big change of over 200, takes the newest reading and sends it to AdafruitIO. There will be a feed flow shows up in the Adafruit IO.

Materials:

  1. ROUND FORCE-SENSITIVE RESISTOR (FSR) or SQUARE FORCE-SENSITIVE RESISTOR (FSR)
  2. ADAFRUIT FEATHER 32U4 BASIC PROTO
  3. CIRCUITS
  4. RISISTORS(1K, 10K, 330)

Challenges:
Putting the final work in a public space and hoping people to play with it is very difficult. People who knows your project will contribute some data. But I hope that people don’t know what’s going on there can also interact with it. So I put the Bunny besides the refrigerator, at the entrance of the building and the third floor of the building where the students have classes all day. The final data file (171 values in all) shows that the interaction happens once or twice per hour during the day time.

Future Iterations:
The Teddy Bunny I got is made for the pets only and when you press on it, it makes noises. So I am thinking make this sensor more durable and powered by a battery. And then I will have a record of the pets owners’ speech so that in future once the pets bite or press the Teddy Bunny, the record will be played. So it is a silly interaction between the pets and the toy.
