Transistor Flasher Circuit Diagram

Here is a one transistor led flasher circuit which will flash a super bright led.

Transistor flasher circuit diagram. It can work as well as the use of ic 555 or other transistor circuits. Can be used on roads for signaling purposes. The transistors do not necessarily have to be bc547 you may use 2n2222 or similar small signal transistors but it is recommended to always use the equivalent transistors. I have many ways but today you see this three of the lamp flasher circuits.

1 in above circuit can the blinker time be adjusted like on for 1sec and off for 1 sec. Power transistors may be added for handling higher current loads. The flash rate can be adjusted by changing the value of 1k resistor used in the circuit. We can create a dancing led circuit by combining many similar circuits which we can use for advertisement boards.

Both npn transistor you can use of bc547 548 or 2n2222. This circuit can be operated using dc 6 12v supply. Circuit diagram blinking led circuit. This led flasher circuit is very easy and simple and there is no ic used.

If you want one a lamp flasher circuit using transistors that flashing for general to use. In the second circuit a power fet is used in place of the npn. The circuit is using single transistor as driver which is taking flash rate from the led 2 which is a self flashing led. This circuit basically works on the charging and discharging of capacitors.

And instead of led how can i connect transistor which can act as a switch the transistor switch will be on for 1sec and off for 1sec 2 the circuit diagram is shown in the link below. The two circuits below are typical connections. The circuit is using 2n3904.
