In order to make the mood lamp work, we needed to order thermistors to read the temperatures of our user's fingers. We decided to order three, and average the temperatures of the user's fingers in order to determine their mood.
While we initially thought we needed a pressure sensor to detect the presence of a hand, we decided to use a photocell instead. Similarly, we got rid of the wifi shield and stuck with plugging the device into a power source.
Finally, we knew we would need several LEDs to output the color that corresponds to our user's mood.
When the users interact with the lamp, they will place their hand on the top of the lamp, and the thermistors (located in the finger tips) will read their temperature. We initially wanted to place a pressure sensor beneath the palm of the hand, but decided to place a photocell there instead, and the change from light to dark would turn the device on, and being reading temperature.
