A tutorial on how to make a Police Lights themed LED Flashing/Blinking LED circuit using 555 timer IC and a few other electronics components. This circuits alternatively flashes between Red LED's and Blue LED's while blinking each of them individually similar to police strobe lights. Explanation of how this circuit works is also included in the video.
You can also club this circuit with police siren circuit, which is the next project in this 555 timer projects series. I add link to it as soon as I upload the video.

Components Required
* 2 x 555 Timer ICs
* LED's: 3 x Red, 3 x Blue
* Resistors: 2 x 1M, 2 x 68R (Resistors for LED's)
* Capacitors: 1uF, 100nF
* Breadboard
* Few Breadboard Connectors
* (5-12)V Power Supply
Note: Depending on the power supply used and the way LEDs are connected (series or parallel) you need to use a different resistor than 68R used in series with the LED's. Refer to the table shown in the video tutorial above for resistor to be used for basic scenarios. You may also visit [ Ссылка ] to calculate the resistor based on LED arrangements.
