We have carried out a teamwork exercise in which a PIC micro-controller is used. The exercise is designed on a key concept that we emphasize on teamwork and student’ s ideas that realize a unique performance of the PIC micro-controller. For this concept we devised exercise equipments, a method of presentation of the results, and evaluation procedure of grades. A hand-made circuit and a breadboard are used so that students can start to make circuits by themselves. Students make presentation of their result operating their circuit and program. We evaluate the grades emphasis on the ideas rather than techniques and knowledge. We also examine circuit elements that the students can use in the exercise. Our experience shows that less circuit elements make more various ideas of a circuit and a program.
