PIC16F84 Multi Siren Sounds Circuit
16 different alarm sound circuit, after running the simulation of the fourth line of dip switches in different positions can run by selecting the 4 × 4 = 16 different sound Remember to press the reset button at the end of each selection. Original ASM file is available.
Example PICmicro Sounds: Police, telephone, IEP, buzzer,laser, etc.
