DFRobot’s FIT0620 electric lock comes with signal feedback for easily checking the state of the lock.
It can be used with other controllers and fittings to add more functions, such as intelligent lock control and IoT(Internet of Things). DFRobot offers a helpful tutorial using DFRduino UNO for relaying the signals. For additional questions, the manufacturer also offers a technical forum: DFRobot Forum
