Construction continued on the solar box ovens. Once they were complete, we learned about Arduino microprocessors. We are using the Arduinos to make a thermocouple circuit so we know the temperature inside our ovens. After a lot of difficulty trying to connect the Arduinos to a Windows computer, a Mac, and a Chromebook, the Windows computer was the only one that worked.
Once the program was working, it was back to the soldering irons so we could make the sensors extend into the ovens. After breaking for lunch the fourth grade stopped by to visit and learn about our IL group. We discussed the process of making the ovens and how to solder.
After setting up the three ovens we were getting temperatures up to 150 degrees Fahrenheit. We will see how well the cookies and marshmallows baked at the end of the day.
The cookies were edible and the marshmallows were gooey.
