China Active Buzzer Sensor Module for Arduino

Active Buzzer Module for steam education
Module description:
Buzzer is a kind of audio signal device. As an integrated electronic buzzer, it is powered by DC voltage and widely used in computers, printers, copiers, alarms, electronic toys, automotive electronic equipment, telephones, timers and other electronic product voice equipment. According to its driving mode, buzzer can be divided into active buzzer and passive buzzer.
The difference between the active buzzer and the passive buzzer: the source here does not refer to the power supply, but refers to the vibration source. That is to say, there is a vibration source inside the active buzzer, so as long as the power is on, it will ring, and there is no vibration source inside the passive buzzer, so it is impossible to make it ring with DC signal.
The buzzer described here is an active buzzer. As long as there is power. We output alternating high and low levels to make the buzzer sound.
