6/10-6/18: Following Jim's directions, I made improvements LabVIEW program. My top priority was to make it perform correctly, turning on the heater on and off when necessary. I suspected that the program developed during the spring semester would heat the air in the box to 72 degrees C and turn the heater off as soon as it passed that temperature. However, when the air started to cool, it would drop below 72 degrees, and the program would turn the heater back on. Thus, the program was designed to keep the temperature close to 72 degrees for as long as it was running.

Thus, the program was designed to keep the temperature close to 72 degrees for as long as it was running.

I tested the program by lowering the target temperature for heating to 35 degrees C and running it, and it performed just as I expected. Jim had told me that we needed the program to heat the air to 160 or 165 degrees F, then turn off the heater immediately and let the air cool to room temperature. I made changes to the program to make it let the air cool instead of keeping it hot, but I also added radio buttons to give the user optional control over the hot plate before the temperature reached the target. After the temperature reached the target, however, the program would turn off the heater and the user could not turn it back on.
