Aiming at the problems of large size,inconvenient carrying and power dependence of traditional e-lectronic organ,this paper designs a touch piano based on solar energy.The touch piano uses STC89C51 chip as the main control chip,equipped with anti-overcharge protection circuit,step-down circuit,51 chip minimum sys-tem,touch switch control circuit and buzzer sound circuit.It can charge the battery through the solar panel to en-sure the long-term power supply to the circuit,each touch switch will make the buzzer sound and achieve music performance.The solar touch piano designed in this paper has the advantages of simple circuit structure,easy oper-ation,high cost performance,small and convenient to carry,energy saving and environmental protection,etc,.It can be used to cultivate children's interest in music,instill the concept of green environmental protection,and has a high promotion value.
