Police Style Strobe Light Circuit

Flashing Police Lights Circuit

This Police Style Strobe Light Circuit using 555 timer ICs shows the familiar lights used on police cars. To achieve this Police Style Strobe Light effect, two groups of LEDs are used. Each group has four LEDs and they turn on and off alternately with like Police Style Strobe light. Whenever a group of LEDs […]

5 LED chaser with transistors

5LEDs Chaser Using Transistors

This simple 5-channel LED chaser using transistors can be used in any application requiring LED light effects. This circuit is build by using npn transistors, capacitors and resistors. 5 LEDs are blinking as shown in this video gif . you can connect more LEDs as this sequence by adding some more transistors.   Step By […]
