Left to do a single light shifted to right, the hardware circuit as shown in Figure 4.4.1, eight light-emitting diodes L1-L8, respectively, then in the P1.0-P1.7 microcontroller interface, the output " 0" when the light-emitting LED light, the beginning of P1.0 → P1.1 → P1.2 → P1.3 → ┅ → P1.7 → P1.6 → ┅ → P1.0 Liang, repeat the cycle.
