How to Make Police Police Strobe Light

About: Share diy projects to those who have the same hobby with me

Hii friend,

Today I am going to make police strobe light circuit using LM555 IC.

Let's get started,

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Materials Required -

Components required -

(1.) IC - LM555 x2

(2.) LEDs - 3V x8 (4-Red & 4-Green/Blue)

(3.) Resistor - 1M x2

(4.) Capacitor - 63V 1uf x1

(5.) Ceramic Capacitor - 100nf / 104 x1

(6.) Battery clipper x1

(7.) Battery - 9V x1

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.

Thank you
