||W01 - Real-time 2D heat flow data as an introduction to what Arduinos can do in your lab
||One of the more useful applications of Arduino microcontrollers in the Advanced Laboratory is as interfaces to modern sensors. The Arduino can communicate natively with sensors using SPI, I2C, One-Wire, and most other chip-to-chip communications protocols. It can then relay data from those sensors to a computer via USB.
As an example of this capability, we've built a 100-point temperature measurement grid onto an aluminum plate. An Arduino tracks all 100 sensors and relays that temperature data to the computer, providing high-precision heat flow data in real time. In addition to providing cool gee-whiz thermal maps of the plate, the data can be used in conjunction with computational modeling of two-dimensional heat flow to provide an interesting Advanced Lab exercise.
The techniques used for this apparatus can be extended to many other applications also. A wealth of sensors exists for measuring just about any physical parameter you might desire. Although these sensors cannot generally communicate directly with computers, they can communicate with inexpensive Arduino microcontrollers which can then serve as data relays. This short workshop will serve as a functional introduction to the techniques necessary for using Arduinos in this way.
