The flex sensor and MPU board had arrived by Monday, but when I went to the Electronics lab on Monday, a woman (lab tech?) named Chloe said that there were classes scheduled, and I could only go back on Wednesday to solder the pins onto the MPU board. Could only play with the flex sensor in the meantime.

The main reference I'm using for the flex sensor stuff is this tutorial from Sparkfun.
The set up looks fairly straightforward, but I realised I didn't have the 47KΩ resistor listed. Since I noticed that the level 4 students seemed to be done with their arduino experimentations, I tried to zip down to the loan store before my tutorial earlier today hoping I could find one.
Spent most of the tutorial time staring at resistor bands and learning about what each stripe colour means. Didn't manage to find the right resistor at the end, but since the tutorial says "Many values from 10KΩ to 100KΩ will work.", David suggested that I try arranging some 10K ones and see what results I can get.
The next step is to get the MPU sensor pins soldered to get some readings off it.
Added note: Met Ian today, who suggested this tutorial when I mentioned I wanted to work with flex sensors. Something to KIV if current stuff doesn't work out.
