Progress 1(TA Meeting)

Oct 1st

Met with TA to discuss our rough idea (as picture shown below) and current progress.

Problems:

• How to control the change of temperature and show its change
• How to control the change of light and show its change
• Do not have any heating devices

Solution:

• Use PID to maintain temperature float between a small range
• Use light bulbs (LED) to show change of light
• Use heating light bulb or hair dryer as heating devices

Others:

• Do not need to make sure the sampling frequency is at more than twice the desired frequency to be measured, since the frequency of temperature data is low.
