on video 12v police strobe flasher led Circuit 🚨

A tutorial on how to make an Adjustable Flashing/Blinking LED circuit using 555 timer IC and a few other electronic components. This circuit toggles an LED or any output device ON and OFF at regular intervals of time. The duration between successive toggling of LED can be adjusted by using a potentiometer.

Watch the video above for detailed step by step instructions on how to build this circuit. Explanation of how the circuit works is also included in the video.

Components Required

555 Timer IC

LED or any output device

10uF Capacitor

Resistors: 100K, 1K, 220R

Breadboard

Few Breadboard Connectors

(5-12)V Power Supply

Potentiometer (Optional)

Relay Module (Optional)

Refer to the resistor table shown in the video tutorial for determining exact value of LED's series resistor (220R)

Circuit Diagram

The resistors R1 and R2, along with the capacitor C1 control the blinking rate. While capacitor C1 and resistor R1 influence both On and Off times of the LED, Resistor R2 is responsible only for the On time. So if you want to try out different resistor values and change the flashing rate, you can experiment by changing the value of resistor R2.
