Buzzer Sensor Arduino Mixly Mind+Python Programming Tracker Robot Module

The buzzer is an electronic sounder with an integrated structure. It is powered by DC power and is widely used as a sound-generating device in computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers and other electronic products. .
The active buzzer can sound continuously when directly connected to a 5V rated power supply. This module can be used in conjunction with the Arduino motherboard to complete the design of simple circuits and achieve “plug and play”.
Passive buzzers can emit various sounds by inputting signals of specific frequencies, and can be connected to the motherboard to make various electronic keyboards.
