This weekly report summarizes the progress of a student group working on an engineering project. In the past week, the group shared work responsibilities for researching an interface rice cooker. Experiments showed that a rice cooker heats rice to 100 degrees Celsius to prevent sticking, and increases temperature to 134-140 degrees Celsius to release steam. The group is working on a triac circuit to control three coils, using isolation to protect the microcontroller. Next week, they will integrate all rice cooker circuits and perform calculations.
