As computing becomes more ubiquitous in our objects, designers need to be more aware of how to design meaningful interactions into electronically enhanced objects. At the University of Washington, a class of junior Interaction Design majors is exploring this question. These pages chronicle their efforts.

Mosfet, Voltage and Button Problems // Stephen and Cami (Post #5)

When we began working on this project, we wanted to use a higher voltage 12 volt light and a n-type mosfet. When we tested it, the mosfte got very hot and the light barely turned on. We decided that the lights were too strong and needed to much power, so we decided to use LED strips and a different mosfet.



Also,  we  introduced the button circuit to our project. Unfortunately that led to us accidentally burning out our Arduino because the 12 volt power and the 5 volt power were on the same side of the breadboard. This made it so 12 volts went surging through the Arduino through a pin, and it isn't equipped to handle so much power through its pins. To avoid this issue, we split the breadboard in half and used one half at 5 volts and the other at 12 volts.
