**Each group is required to get a protoboard and a PCM-E set, before the experimentation
date. Connect circuit that shown in Figure 5 without components: 1) P1(10K) and DC motor
from PCM-Mxx, 2) P2(10K) from PCM-Sxx, and 3) a K from PCM-Pxx. Read the procedure
carefully and answer the following questions.
