5 PCS buzzer module passive LED control low trigger sound module 3.3.5V 3 PIN for projects

Passive buzzer without oscillating source inside, so if you use signal, you can t make it scream. It must be driven by a of 2K.5K. The sound frequency is controllable, and the effect of do re fa so la si do can be made. In some special cases, a control port can be multiplexed with the LED.
