光耦隔离驱动继电器，隔离开主电路和控制电路-Optocoupler isolation drive relay, isolated main circuit and control circuit

控制电机岩石正反转 ，带延时 防止电机烧毁(Control motor rock positive reversal, delay to prevent the motor burned.)

通过单片机GPIO口控制继电器的吸合。带光耦隔离，安全可靠。亲自适用该电路参加电子设计大赛有效。(The pull-in of relay is controlled by GPIO port of MCU. With optocoupler isolation, safe and reliable. It is effective to apply the circuit in person to participate in the electronic design competition
