Example 2: Buzzer Gives an Alarm

Overview

To make the buzzer give an alarm.

Hardware Buildup

Same with【Experiment 1: Buzzer Makes a Sound】.

Mixly Programming

  • Adopt "For loop" to change frequency, with which you can change the tone. (The lowest frequency that human ears can hear is about 20Hz and the highest is about 2000Hz. )
  • Find "Loop" in "Control" item and drag it to the editing area.
  • Instruction for "Loop".

Debugging

  • Step1: Select the right board card(Core USB 32U4) and COM port(Recognized automatically by default).
Mixly board COM.jpg
  • Step2: The buzzer will produce different sounds continuously after uploading successfully, achieving the effect of alarming.

Experiment 3: Compose Music with Buzzer

Overall

To use a buzzer instead of an audio speaker to play music and generate sound with different tones.

Hardware Buildup

Same with【Experiment 1: Buzzer Makes a Sound】.

Mixly Programming

Let's firstly get to learn numbered music notation-Note.

Mixly yinfu 2.jpg
  • Here we adopt the way of array to play music, which is flexible in programming.
  • Drag out "Array" item.

Debugging

  • Step1: Select the right board card(Core USB 32U4) and COM port(Recognized automatically by default).
