Description: 实验箱的蜂鸣器是交流蜂鸣器，在BZSP输入一定频率的脉冲时，蜂鸣器蜂鸣，改变输入频率可以改变蜂鸣器的响声。因此可以利用一个PWM来控制BZSP，通过改变PWM的频率来得到不同的声响，以此来播放音乐。-Experiment Box AC buzzer buzzer is in BZSP certain frequency pulse input, the buzzer beeps to change the input frequency can change the sound of the buzzer. So you can use a PWM to control BZSP, by changing the PWM frequency to get different sounds in order to play music. Platform: |

Description: 定时器可以发出不同频率，不同占空比的pwm波。当蜂鸣器接收这些波形时，由于频率和占空比的不同，它会发出频率及声音大小不同的响声，即不同的音色和响度。这样就可以唱歌了-The timer can emit different frequencies, different duty cycle pwm wave. When the buzzer receive these waveforms, due to different frequency and duty cycle, it emits sounds of different frequencies and the size of the sound, that is, different timbre and loudness. So that you can sing Platform: |

Description: 本设计是以TI公司的MSP430G2553和LDC1000芯片为核心设计的一个金属物体探测定位器。采用MSP430G2553单片机作为系统控制处理器，LDC1000电感/数字转换器评估板作为金属物体探头对硬币及铁环进行探测，当检测到硬币或铁环时单片机通过反馈信息控制小车不动而实现定位。同时，运用PWM直流电机调速技术，完成对小车运动速度和运动方向的控制，并用蜂鸣器和发光二极管进行声-光显示是否探测到硬币或铁环。整机使用单电源同时对电机部分、芯片部分、显示部分进行供电。-The design is based on MSP430G2553 and LDC1000 chip of TI company as the probe positioner of a metal object core design. Using MSP430G2553 singlechip as the system control processor,LDC1000 inductor / digital converter uation board as metal objects on the coins and ring detection probe. When detecting the coins or ring when the singlechipr through the feedback information to control the car does not move and position. At the same time, the use of PWM DC motor speed control technology,complete control of the car speed and direction of motion, and sound and light whether the detected coins or ring buzzer and light-emitting diodes. The use of single supply at the same time, the electrical part, the chip part and a display part for power supply. Platform: |
