Introduction: How to Make Police Police Strobe Light
Today I am going to make police strobe light circuit using LM555 IC.
Let's get started,
Step 1: Materials Required -
Step 2: Circuit Diagram
This is the circuit diagram of this project.
Connect all components in IC according to this circuit diagram.
Step 3: Connect Both ICs
Firstly we have to connect both ICs by soldering it's pin-1 to pin-1 and pin-8 to pin-8 of both IC.
Solder pin-1 of IC-1 to Pin-1 of IC-2 and
Solder pin-8 of IC-1 to pin-8 of IC-2 as solder in the picture.
Step 4: Short Pin-2 and Pin-6 of Both ICs
Next we have to connect pin-2 to pin-6 of both ICs.(we have to short pins in both ICs).
Step 5: Connect 1M Resistor
Next connect 1M Resistor to the IC.
Solder 1M Resistor between pin-2 to pin-3 of ic.(Connect Resistor in both ics) as you can see in the picture.
Step 6: Connect 1uf Capacitor
Next solder +ve pin of 1uf capacitor to pin-2 of 2nd IC and solder -ve pin of capacitor to pin-1 of both ICs as you can see in the picture.
Step 7: Connect 100nf Ceramic Capacitor
Solder 100nf ceramic capacitor between pin-2 of IC-1 and pin-1 of both ICs as you can see in the picture.
Step 8: Make LEDs Like This
Make LEDs like this connect it's legs according to the circuit diagram.
Step 9: Connect LEDs to the Circuit
Next connect LEDs to pin-3 of both ICs as solder in the picture.
Step 10: Connect Battery Clipper Wire
Now solder +ve wire of battery clipper to pin-8 of the both ICs and -ve wire of battery clipper to pin-1 of the ICs as shown in the picture.
Step 11: Circuit Is Completed
Now circuit is completed so connect battery to the Battery clipper and see the light of LEDs like as Police strobe light .These LEDs will blink to copy as police strobe light.
This type we can make police strobe light using LM555 IC.
