This article describes the The simple LED Flasher (CD4011). The content is very simple, very helpful. Components in this article can help you understand better understanding of this article. For example, in this article, you can go to find and buy these components: CD4011.

This is simple a led flasher circuit that I would link to suggest you make it.But before you can use transistors,which difficulty when we learn about digital ICs. In particular, IC 4011, which has been very popular.
From this circuit : Easy Lamp Flasher by IC 4011 I apply to new stye display with a Single LED, by I use cool digital IC , GATE Flasher IC-4011 quad nand gate.
so the Flashing output frequency = 1Hz. The IC 4011 ‘s Input pin 1 use for Control LED ON or Flasher.
Logic = Low (LED ON) , Logic Hi = LED Flasher. I like this circuit because it is easy to make.
Detail more, Please read in this image circuit. and you can see the next circuit ofTwo LED Flasher

IF you want the small circuit two LED Flasher, I show this circuit.
The important part of the circuit is IC 4011 again, I used gate of IC 4011 (see image).
IC wired as an astable multivibrator generating a 50% duty-cycle square wave at about 1Hz frequency.
Two LEDs are flasher to alternate.
To change value C1 and C2 for other flasher ratio.
Detail more, Please read in this image circuit.

This is Easy Lamp Flasher Simple lamp flasher, I usesNAND Gates IC 4011.
Circuit is an astable multivibrator generating at 50% duty-cycle square wave about 1Hz.
The C1 – 47uF capacitors and R1 – resistors are determine the flasher rate frequency.
You must uses High current power supply for lamp only.
I use power mosfet for driver lamp because it have high power and easy than transistor.
please see part of circuit in image.
