Capacitive Fingerprint Scanner - UART (AD-013) - OBSOLETE

Buzzer alarm to convert electrical signals into intermittent acoustic signals in robotic devices and Arduino projects

A buzzer with a pulsating tone generator, after connecting the supply voltage (DC) in the range of 3V -24V, the buzzer generates an intermittent signal with a frequency of approximately 1 Hz. Application example: as a reverse alarm system for a car.
