Device Prototyping Process Blog

Major hurdles

Sorting the littleBits pieces

To create a prototype, we first had to figure out how to use littleBits. We completed the tutorial and quickly learned the basics. It was much more difficult to learn how to accomplish what we wanted to do, in fact we were unable to have a button turn off the alarm as we wanted it to. We spent a lot of time rearranging sensors and outputs, learning through trial and error. However, in the end, we were able to accomplish our goal of creating a functional prototype. Here is my video submission:

One of the prototypes if an alarm system we created


We were quickly able to turn on an alarm, but turning it off was not so easy. We tried to add a button into the circuit but could not figure out how to make a press of the button turn the alarm off. If I were to do another project like this one, I would spend more time learning the basics of the tools I was using, because I did not fully understand how certain aspects of littleBits worked. I also learned how incredibly valuable prototypes can be, as this prototype revealed many flaws with our idea.

What did your prototype teach you about the product you were trying to make?

I quickly realized through prototyping how impractical our device was. The thermometer would need to be placed in the pot or pan for the device to work, and a wire would have to run from it to a speaker. I also realized that the system could not be desirable unless we figured out a way to turn off the alarm with the press of the button, as the simple timeout we were using could be very annoying. The biggest issue with the system we attempted to create is that we are expecting child who forgets that they are cooking something to remember to turn on and set up the system, which is not realistic.
