What is blinker circuit?
The Blinker module turns a direct current input into a square wave output, allowing you to make LEDs blink and Buzzers beep. This circuit blinker has a green LED flashing in time with the output and a red LED to indicate if power is connected the wrong way.
How do you make a blinker?

What kind of circuit is blinking two LEDs?
Blinking Two LEDs Using Transistors. The circuit for blinking an LED using transistors is called an Astable Multivibrator. To understand this circuit you need to know how voltages and currents behave around resistors, capacitors and diodes (which is something you can learn in Ohmify). Here’s an overview of what happens:
What kind of transistor is used in blinker circuit?
The blinker circuit design is made using the LM395 IC. This IC is a short-circuit proof power transistor with special characteristics. This is sometimes called a “super transistor”. LM395 is used in this circuit as an alarm blinker for cars.
How is the blink frequency of a car determined?
This IC is a short-circuit proof power transistor with special characteristics. This is sometimes called a “super transistor”. LM395 is used in this circuit as an alarm blinker for cars. The blink frequency is determined by the R4/C1 combination which is dimensioned to give approximately one blink per second.
How to make a simple LED flasher circuit?
Simple LED flasher circuit can be designed by using timer IC 555, as we know the timer IC has internal voltage divider made by three 5KΩ Resistor hence the timer IC referred as 555. These devices are precision timing circuits capable of producing accurate time delays or oscillation.
