Input / Output Coincidence Lab Assignment
Description:
SqueakySock is a medical device prototype that provides audio feedback to help PT patients limp less during recovery from ankle injuries.
Description
The Genie in the bottle begs you to let it out every few seconds. When you open the lid of the jar it celebrates its release and then plays a little melody. Putting the lid back on makes play a sad melody and resume begging to be let out again.
Based on the Melody example for K3, the code for the different states quickly got very complex and pausing the music, but still sensing light changes was also a challenge. I hope to clean it up (maybe splitting into classes) at somepoint.
Description:
The goal of my project was to create a level that signified an even plane based on the distance from the photocells. When both ends of the cardboard are equidistant from the photocell, the music would turn on. The only issue I had was that the values of the photocells differed in sensitivity too much, and it was too difficult for me to find the correct interval to make the music sound.
Material:
Arduino board
chopsticks
tape
cardboard
scissors
wires

Description
For this lab I sought out to combine the photocell with the piezo speaker to create a device that will change the pitch of a preset tune using the amount of light captured by the photocell.
Materials
- Arduino Uno
- Photocell Resistor
- Piezo Speaker
- 220 Ohm Resistor
- 10K Ohm Resistor
- Many Wires
Code
Description:
The 2-note Jaws Theme plays on the piezo speaker; the temp is controlled by the POT in an attempt to simulate Jaws getting closer. I tried to get it to where when the tempo got really fast, a sound file of a scream would play, and an image of Anne Hathaway getting eaten by a shark would pop up on my screen. However, I couldn't quite figure out how to do this.
Parts:
Breadboard
Piezo Speaker
Pot

Description
For this lab I designed a TUI that imitate the kitchen stove. The pot is used as the knob. When starting a fire, you need to push forward as you would do to the real stove. The push pressure is detected by FSR and a quite complex logic is used to calculate whether the fire can be turned on. While turing on the fire, the speaker makes a continuous clicking sound. After the fire is turned on, the LED represent the flame and their brightness is adjusted according to the knob position. Photocell is used to detect whether a pot is placed above.
Description
In this assignment, I created a radio. When you turn on the radio, it's not tuned to a right channel so that it makes noise. By rotating a pot on the radio, you can tune channel. And, once you get a signal, it plays music.
It has three channels. Try to find them!
