The pin-out of the UM3561 is shown in figure 1. Pin 1 is the pin on the bottom left when the IC is held horizontal with the writing the correct way up. The little notch in one side also helps to identify pin 1, as does the small white dot next to this pin.
The IC's power supply (3V DC) should be connected between pins 5 and 2. The sound effect output from pin 3 can be connected either to a piezoelectric sounder or to a small 8Ω, 0.2W loud-speaker via a BC107B transistor.
In the circuit diagram of figure 2, pin 6 has been connected to the common terminal of an SPDT centre-off switch so that any of the three siren sounds may be be produced when the power is on. The machine gun sound effect can be played by pressing the Gun button when the power is on. Of course, should you only need to use one of the effects, you could hard-wire pins 1 and 6 as appropriate.
#UM3561Siren, #PoliceSiren, #Ambulance Siren In this video i am going to show you how to make 4 in one Siren Generator circuit using IC UM3561, it is a Melody generator IC and can be used to make - 1) Car reverse siren, 2) police siren, 3) fire brigade siren 4) Ambulance Siren 5) Machine Gun siren, 6) Car indicator siren, 7) Siren for Science project, 8) Warning Siren Circuit is quite simple and only minimum 4-5 components are needed to make it List of ITEMS 1) IC UM 3561 2) BC 547 / TIP 32C 3) Speaker 4) Variable Resistor 47 K 5) Resistor 100K x 2 6) Push Switch Circuit Diagram : https://electronics4ubymanmohanpal.blogspot.com/2021/01/ic-3561-siren.html
