Designing a Music Box Based on 51 Microcontroller Today we will design an interesting music box project that combines the LCD1602 display and a buzzer to allow our microcontroller to play music. System Design Block Diagram Note Frequency Table // Note frequency definitions (unit: Hz) unsigned int TONE_TAB[] = { 523, //do-low 587, //re 659, … Read more
unsetunset1. Module Introductionunsetunset The buzzer is a sound output device commonly used in embedded systems, capable of emitting alert tones or alarms through simple level control. In STM32 development, using a buzzer can achieve functions such as: User interaction feedback (e.g., key sound effects) Abnormal state alarms (e.g., sensor failure) Power-on indication sound Sound output … Read more
1. Project OverviewThis project is themed “Sports Data Assistant,” guiding students to comprehensively apply sensor technology, graphical programming, and mechanical structure design. Through phased tasks, students will create an intelligent basketball scoring assistant device with counting and prompting functions. The project deeply integrates the Doubao Classroom Assistant AI, providing students with real-time learning support and … Read more
<Click above Microcontroller and Microcontroller Development Community Follow this public account:)>Introduction:We will adopt the same layered design approach used previously for the button module and display module to design the buzzer module. Similarly, performing layered design on the buzzer module is a good practice that helps provide maintainability and reusability of the code.Below, we will … Read more
The GPIO port connects to the BEEP pin of terminal J2, allowing the buzzer to sound by inputting a high level on the GPIO port. Frequency: Pitch, kHz Duty Cycle: Sound intensity, 0~100% The duty cycle is the ratio of the time the high level is on to the signal period: Duty Cycle = (Time … Read more
In previous sections, we used the GPIO output function for the LED lights. This time, we will finally need to use the GPIO input function. The human infrared sensing module is quite simple to use. After completing our experiment, we will combine it with the previous buzzer to create a simple human detection alarm. 1. … Read more
The buzzer is a common device, which can be divided into passive and active types. Choose different types of buzzers based on project requirements. In a recent project, we used an active buzzer. As usual, we first designed the circuit board and then proceeded to programming. The schematic in the project is as follows: If … Read more
How did I come up with the idea of making a music box? With International Women’s Day approaching, QiuQiu said he wanted to give me a gift, and also a big present. QiuQiu made a small bag by himself and asked me to buy some chocolate online (he promised to pay with his pocket money … Read more
