Avoid Regrets: Upgrade Your DIY Police Strobe Light :NE555-ATTiny

DIY police strobe light is a cool project.

Download the Code and Schematic:   / diy-police-light-111115447  

In this video, I am showing you how to make a police light circuit by using NE555 IC, transistors, and LEDs, and then how to upgrade it to a microcontroller version.

This circuit is a combination of the NE555 pulse generator circuit and BC547 transistors multi-vibrator circuit as well as the upgrade version is an Attiny microcontroller-based circuit.

In this video, Attiny chip is programmed by using Atmel studio and if you like, you can use Arduino also to program the chip.

Warning!
This video is for electronics education and entertainment purposes only. some countries may have legal issues with using this kind of light in public If you are willing to use this kind of light in public please use it at your own risk within your country's legal frame.

The circuit's component values are designed to 5 volts DC.
