Introduction to Physical Computing
Week 3, Lab- Analog In

Here is the ITP intro physcomp link for the lab.

Step 1.

First I connected the breadboard to the Arduino.



Step 2.

Next I connected a potentiometer, as per the lab instructions. As you
turn the potentiometer up and down the green LED's intensity changes
accordingly.



Step 3.

Next I connected a variable resistor. I used a flex sensor and
programmed the arduino to send the reading from the sensor back to the
terminal so I could monitor change. What I noticed about the flex
sensor I was using was that it registered bending in only one
direction. I made a mental note to be careful how I integrate the flex
sensor into future projects.



Step 4.

Have fun! For the final step in this lab we were suppose to create a
luv-o-meter. My luv-o-meter works for guys only. It is a modified pair
of pants which was a flex sensor along the zipper line. When you first
put the pair of pants on, in an unaroused state, you press a button
which takes the initial flex reading. After an, um, change, a red LED
blinks on and off to indicate a high reading on the meter.

The main problem with this project, as with the the chimes, was securing
the arduino in an ungangly fashion. Next, there was the obviously
problem that the luv-o-meter registers a high reading whenever you stand
up.
