Abstract

The invention provides a free pendulum Light-Emitting Diode (LED) display system used for practical training and belongs to the field of teaching experiment training. The free pendulum LED display system used for the practical training solves the problem that experiment instruments of the free pendulum is complex and not direct-viewing in operation in an existing experiment class. A fixed support is connected with one end of a swing rod through a rotating shaft, the swing surface of the swing rod is vertical to an axis of the rotating shaft, and the other end of the swing is in a flat plate shape. The surface of the flat plate is provided with a LED, an angle sensor is used for measuring a swing angle of the swing rod, and a second wireless module and a second microprocessor are placed on the fixed support. A wireless signal input end of the second wireless module is connected with a wireless signal output end of the second microprocessor, a swing rod angle signal input end of the second microprocessor is connected with an angle signal output end of the angle sensor and a light-emitting diode drive signal output end of the second microprocessor is connected with a drive signal input end of the LED. The free pendulum LED display system used for the practical training is used for a training of an electronic experiment.
