 This article describes the Simplest led flasher IC circuit (CD4026). 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: CD4026.

Today I would suggest a flashing light that is very simple. Because we use Numbers packages of IC LM3909. Advantage of them is used instead of the original circuit. Using dozens of transistors easily. By you add a capacitor and a resistor for each one. The LED is blinking fast.
In addition, it has very low power consumption, for example, a 1.5V battery could drive the LED flashes. And also current is only 0.3mA. you so use it many months.

Consider the following circuit.

Battery 1.5V or 3V Monitor using LM3909

We come to add LED Flasher for Monitor the electric current of battery 1.5V and 3V. By use the integrated circuit LED Flasher or Oscillator. By the rate something flasher equal to 2V. This circuit eats electric a little current poor age the work of battery long can’t be like be usable. If friends use battery 3V as a result liberate pin 1 float keep. I hope that a friend may apply with Battery 1.5V or 3V Monitor Circuit , please sir.

Fast LED flashing 1.5V

Fast LED flashing 1.5V
The Fast LED flashing circuit. that apply to AA Cell 1.5V. By add resistor 1K size between pin 1 and 8 pin of IC number LM3909. It will rate winking expansion 3 again times. When build capacitor 330uF sizes suit 1 pin and 2 adaptation pin modify by the tow electronic part outside. It make way for choose for resistor outside equal to 3K,6K and 9K. Other detail , see in the circuit.

LED Display for power supply 6V or 15V by LM3909

This circuit uses the integrated circuit LM3909 perform be LED Flasher and Oscillator. For Drive LED give Flasher on – off with Frequency 2Hz. For formed show of office equipment with Battery For battery 6V size Capacitors. CT be valuable 400uF, Rs be valuable 1000ohm and RFB be valuable 1500ohm. For voltage 15V size the value of , CT equal to 180uF Rs equal to 3900ohm and RFB equal to 1000ohm. The useful life of battery long because of the circuit uses a little electricity.

One LED display flashing low volt

One LED display flashing low volt
This circuit is LED display flashing with one LED. By when you press Switch S1 give wasp the circuit then to liberate. It as a result make LED1 bright about 0.5 second. By this circuit uses the integrated circuit of NS number LM3909. It is build the mono stable multi vibrator circuit produce low frequency. It uses low power supply 3V only just.

3V Lamp flasher High Current by LM3909


If you like to use the integrated circuit LM3909 build be Flasher Circuit. But may get into trouble about apply to Lamp at have the requirement Current tall no. I then introduce to see this circuit can apply to power supply 3V and apply to Lamp 3V 1A get. By use transistor help enlarge current tallly can go up for the rate something flasher of lamp can then poor Lamp stick bright can be unfinished. By the circuit uses the integrated circuit makes flasher get. By build transistor a kind NPN that durable Current 1A or tall more build stay the outside. This circuit can use to is Lamp warn at fine the frequency of something Flasher get. For use advertise or show the something. By lamp at have reflect large-sized stay within a darkroom will fine give wink with tall speed That will do see to is actor picture stops something K rumor can shake. Friends , may get circuit this idea goes to apply please sir.
