The invention belongs to the technical field of piano prompting equipment, and provides a control method and system for an LED water lamp of a piano prompting device, and the method comprises the steps: S101, storing a music score needing to be played through a storage module; s102, extracting notes, tones and beats in the music score through an analysis module, forming a running water lamp control signal of the corresponding note according to the sequence of the notes in the music score and the tone corresponding to the note, and sending the running water lamp control signal to a peripheral control circuit; s103, controlling each column of running water lamps to light up in sequence through a peripheral control circuit; the system comprises a piano prompt board and a controller, wherein the controller is connected with the piano prompt board through a peripheral control circuit. According to the control method and system for the LED running water lamp of the piano prompting device, the position of the next key can be obtained in advance, the difficulty of estimating the playing starting time by a user is reduced, and the playing accuracy of the user is improved.
Description
technical field [0001] The invention relates to the technical field of piano prompting equipment, in particular to a control method and system for an LED running light of a piano prompting device. Background technique [0002] A piano is a keyboard instrument in which the keys pull the hammers to strike the strings. Since the piano is the instrument with the widest range except the organ, it is widely used for solo, ensemble, accompaniment and other performances. At the same time, it is becoming more and more popular. [0003] In order to allow more beginners or music lovers to learn and play a piece of music faster and more smoothly, by installing a key prompter on the piano to prompt the beat or syllable of the piece, it will help beginners or music lovers memory. [0004] The existing piano prompting device indicates an operation button through an indicator light, and prompts the user to operate each button by turning on and off the indicator light. However, a light in...
