There is no oscillator inside the passive, so if a DC signal is used, it cannot scream. A square wave of 2K~5K must be used to drive it.
Passive buzzer, need input oscillation frequency in the I / O ports, and the buzzer will sound.
The frequency of the sound is controllable, and the effect of "do re mi fa so la si" can be made.
Operating voltage: 3.3V~5V; The module is driven by a 9012 transistor.
Fixed bolt holes for easy installation. Uses 3 pin control port.
