Lab 4 - Sensors: Force sensitive resistors and photocells

Start Date: 
Thursday, September 20, 2007
Due Date: 
Thursday, September 27, 2007

Use force resistive and photocells sensors as input and use variable LEDs (build on the pulse width modulation exercise from Week 3) as output; consider multiple force sensors and photocells?


Create an interesting visualization on your computer that could be influenced by the input from the sensors you have (pot, photocell, FSR, or combination of them). You can use Processing (or any other language you like) in writing the program. Post your results on the course website.

Create a mechanical construction for your FSR that distributes or focuses physical force that is applied. Think about everyday objects (toothpaste tube, entrance mat, paintbrush, pipette, etc.) and how you measure the pressure or force applied to them.
